Tips for RC plane flying in strong winds

whiteboard died McGee and everyone loves

whiteboard videos here's another one the

equinox is coming the that's the

transition between summer and winter or

winter and summer it's the time of year

when the length of daylight hours is

about the same as the length of

nighttime hours so it's also the time of

day when weather systems start warming

up we have the the the warm and the cold

start mixing we start getting some

really powerful weather systems which

means wind lots and lots and lots of

wind about this time of year it's called

the equinoctial gales and some people

just prefer to sit inside and watch the

trees wave around but me no no I

actually prefer to go flying and today

on the whiteboard I want to talk about

flying in wind because it is for some

people one of the scariest things they

ever do but for people like myself it's

one of the most fun things to do now

flying in wind you might be would be

dangerous but tricky but difficult no

it's it's not actually it's a lot of

myths about flying and wind I'm trying

to spell some of those myths today and

i'ma show you some of the basics of how

to fly safely and wind without Rick in

your model and without endangering other

people so here are some basics tips did

start with a first step the first thing

is your choice of the model you need to

choose a suitable model if you've never

flown in strong winds before if you want

to get used to and learn how to fly in

strong winds you need to choose a model

that's suitable that means probably not

a Spitfire not an EDF jet not a biplane

you want something that's simple

something like an ax n or a Bixler or

something like the if it is super easy

which is my choice for this particular

video you want a model that is

predictable that has a wide reasonably

wide speed range has a good power of

weight ratio and something that you've

flown quite a bit before something you

feel comfortable flying because flying

is strong winds especially if this

tubulin surround can really test your

flying skills but it's like everything

the more if it something requires the

more reward the more fun the more

pleasure you get from doing it nets

we're flying in wind is so good right so

you need to choose the right model right

moral choice and I don't mean Claudia

Schaffer or whatever her name is Choi

said his book choice today is pellet so

number one model choice choose the right

model and that will go a long way

towards ensuring that you're flying on

winter successful now the next thing is

number two check your model flying in

the wind can put a lot of stress on the

airframe because you get things wrong

things happen a lot more quickly you may

find yourself pulling more G's and you

may find yourself let's face it

crashing it's going to happen you're

gonna crash so you need to check the

model make sure the linkages are secure

make sure that the the wing is firmly

mounted if it's oh and I recommend a

conventional layout model for learning

to fly flying wings is not so much fun

they get thrown around more for a start

they till gets thrown around around a

lot in strong winds it's a conventional

layout like an ax in AB X or if it me

super easy whatever much better choice

but check the model make sure there's no

linkage is about to pop off make sure

the hinges are secure so you're not

gonna lose an aileron or an elevator

with obviously unfortunate results and

make sure the wiring is good so you want

to be able to rely on this model you

don't want unexpected things happening

just at the moment you most need full

control so check your model right

next thing is check your flying area

number three flying area is important

why is it important because there are

two aspects to flying and strong when

the first thing is you're gonna have

wind okay wind is easy to handle wind is

not a problem turbulence is a problem

hariom so let's assume that you are out

here here's a flat field here's you and

don't I draw you world ego and here is

your model let's draw a little plane

here the wing and a propeller and wheels

Matt preps there you go you've got a lot

of wind blowing along here that's fine

because believe it or not once your

model leaves the crate once it leaves

your grip or the ground it doesn't know

there's any wind it really doesn't know

there's any wind once the model has left

the ground wind no longer exists because

all relative I'll talk about that a

little bit more later but these your

model flying great if it's a steady

constant breeze it's piece of cake

pace okay but what often accompanies

strong wind is turbulence and that is

really far more exciting far more

difficult far more fun to fly and so if

you're just learning you don't want the

turbulence you want a nice steady breeze

you can cope with it very easily so you

want to make sure if you

to fly in a strong wind stay away from

things like houses trees or anything

else that's going to cause the wind to

become turbulent and gusty because

that'll make your flying experience much

more difficult so you want to stay away

from these things you want a nice open

expanse with nothing upwind of you if

you can avoid it that gives you a clear

understood if flow easy to fly and even

a strongest one makes it much easier so

there you go flying area is important

also you want to look downwind take a

look at the winds come this way take a

look down this way because if you do

lose control of your model and he gets

blown downwind where's it going to end

up you don't want it disappearing in

over a busy road or something so you

need to have an area that gives you

enough room to get a model down if you

decide well it's got too far away I need

to dump it dump it in a safe area so

your choice of flying spaces until

you're really good at flying when a

strong wind becomes a little more

restrictive you're got to make sure you

choose the safe options and these are

the safe options there you go now

assuming assuming you've got all that

sorted the next thing is what you need

to do is your basic flight procedures

the first thing is flying in a strong

wind you want to get your model off the

ground or out of the launch as quickly

as possible you don't want to Delia

around near the ground because the

ground is the only thing that's gonna

break your model so the sooner you get

away from it the safer you're going to

be which means if you're flying

something with wheels take off climb

reasonably steeply don't risk a stall

but fly steeply upwards so you got a bit

of separation you've got a few mistakes

of altitude because altitude is your

friend you make a mistake you've got

time to recover if you're flying at 10

feet and you make a mistake

you've only got time to pick up the

pieces so you want to climb quickly so

from the takeoff

you want to climb quickly there you go

get up get some safety get some safe

altitude under you and that gives you

more room to move now I'm gonna draw a

picture here we are here are you I'm

gonna look down on your head here we go

that's you here there's your feet

well here's your transmitter so we're

looking down onto you this your head

press looks a bit better and here's the

wind direction that's blowing this way

right so here comes the wind now here's

your model let's put your model down

there's propeller you take off into the

wind always take off into the wind

directly into the wind if you take off

with a crosswind your model might tip

over on take off or if you're launching

it may get caught by the wind and

flipped into the ground so always take

off directly into the prevailing wind

and that means that you you'll be much

more stable out of the launch of the

take off product so take off now the

next really important thing I cannot

emphasize this too much because I've

seen so many people get into trouble is

imagine a line along here right your

course

I know I've crashed much my markup in

you always want to be flying upwind of

this line you do not want to fly back

over your head you want to be upwind and

preferably you know quite a way upwind

and why would you do that well I've just

mentioned being a few mistakes hi they

say got room to recover if you make a

mistake now one of the problems that

most people face at some stages they

might get disoriented put a wrong

control input in and with us if you're

flying on a calm day it's not that much

of a problem because the model you know

you just recover it and keep flying but

if you're flying in a really strong wind

and you're up here and you make a

mistake

it only takes a very short period of

time for the wind to blow the model

right back over your head and then it's

behind you and then you're in trouble

because if you still can't get

orientation it's just going to get blown

further and further away until it

disappears or you dump it on the ground

so stay upwind so if you make a mistake

because you get disoriented it's just

gonna blow the model closer to you so

you get a better look at it it gives you

a more chance to make a recovery and

keep flying

so always fly in front of yourself into

the wind never behind yourself and that

can involve initially if it's a strong

wind you might find that you don't

actually have to do any circus takeoff

and you can just fly to the right to the

left to the

if to the right so you can do an East

you can fly Anna and it is pattern and

because you've got the wind constantly

bringing you back

you'll fly in front of yourself even

though you're going from side to side

and forwards you'll end up sitting in

roughly the same piece of airspace it

gives you time to get familiar with how

the models handling in the wind and get

a feel for it get the nerves to we're

off because it is quite nervous the

first few times so you get rid of your

nerves that's fine now if you want to

fly a circuit and I recommend you do

left and right in silicates to get used

to it then again don't fly around

yourself fly up then fly back around

like that

so you're still always in front of

yourself always in front of that magical

line

so if you make a mistake here and I went

the wrong way and you come back you're

still going to be in fronting that's

going to blow the model towards you if

you fly around a circuit like this and

you make mistake here you might end up

way back over there because the winds

blown you so we stay in front of the

magic line absolutely important so I

recommend that you do figure eight so

you fly around there then come around

and do a figure eight that way and just

you know get again get familiar with the

model to see how it handles and then

gives you plenty of wiggle room your two

mistakes hi and your a mistake or two

upwind and then the mistakes won't

matter quite so much and now I want to

talk about a few of the myths there are

a lot of myths involved and flying them

when one of them is the fear of a

downwind to know people who say if

you're flying into the wind and you turn

down when do you risk stalling the model

may stall because suddenly it doesn't

have the same amount of wind going over

the wings which is utter rubbish excuse

my french

it's utter bullcrap know the model as I

said earlier on doesn't know it's flying

in wind if you think about what wind is

imagine the model is flying around in a

circle

when does simply the fact that the

ground is moving underneath it the

ground is moving in a general direction

the airflow is constant apart from

turbulence so the model is if you fly in

a in a full-size aircraft once it leaves

the ground you don't know there's wind

apart from a little turbulence you don't

know which way the winds blowing unless

you look out there and and work out

which way the your general drifters once

you're in the air the only thing that

moves relative is the ground and and

when there's no such thing as stalling

on a downwind because the wind is so

strong what happens is what tends to

happen is that if there is a lot of wind

it's a the winds coming this way like so

and your model is flying into the wind

just accuse it that's a crappy - excuse

for a model isn't it you're flying into

the wind like this okay the model will

appear to be flying quite slowly because

obviously the wind is coming right so

the ground speed will be lower than the

air speed so flying in a normal air

speed the model will have quite a low

ground speed with a strong wind so

you'll be flying up here and you might

think I'm going to turn back downwind

and then what happens the reason that

sometimes people tend to stall their

models when they turn downwind is

nothing to do with the the

wouldn't blowing over the wing or

anything like that what happens is here

you might have a ground speed so your

airspeed is a hundred kilometers an hour

but it's a 50k wind okay that means if

you subtract the wind speed from the

from the ESP you get a ground speed so

this is ear speed you get a ground speed

of 50 ground speed so the model appears

to be traveling at 50 kilometers an hour

okay because well that's traveling at

100 K through the air the wind is 50 K

so it looks like it's flying quite

slowly now when you do this turn here

suddenly the model is going to

accelerate quite a bit because you have

100 K of air speed plus 50 K of wind

speed so now you're going to be doing

150 kilometers an hour relative to the

ground so the natural tendency when

people see that if they're flying in

wind they're flying slowly into the wind

they do a turn the model speeds up

nothing oh so they cut the throttle and

pull on the elevator to slow down and

that's when bad things happen because

the model itself is traveling the

exactly the same air speed as far as

it's considered it hasn't changed speed

it hasn't changed speed but when you try

to slow it down to the same speed you

were doing into the wind suddenly if you

want this to do 50 kilometres an hour

going downwind then you've got 50 K wind

it will stall and fall out the sky

because they'll have no air speed so you

need to realize you need to appreciate

that wouldn't model Goes Down when it's

going to travel much faster than when

it's traveling into the wind so don't be

surprised when it starts speeding up

down wind and don't try and compensate

for it don't try and slow the model down

or you'll stall it because you'll run

out of air speed hope this so

understandable but yeah and that's why

some people when they fly and they tune

down wind and hold on the elevator to

slow the model down it stalls and falls

over the ground and what death what they

mistakenly think is gosh it's stalled

because now the wind is blowing behind

and there's not much when flying over

the wing nothing to do with it you've

slowed the model down to the point where

it stalls so that's why I recommend

doing those circuits in front of you to

get a feel for how fast the model is

going to go up and down wind and don't

play around the elevator too much just

keep it level don't try and slow it down

and keep a constant

fawful sitting don't try and slow the

model down on the downwind leg or you do

risk stalling and again that's why I say

use a nice predictable model if you've

got something like the FMS super easy

they don't really stall they just mush

and you'll be able to see well what's

going on I've got it's getting all

wobbly there's no control response but

it's not falling out of the sky so

something with a nice constant cord wing

really relatively lightly loaded now

some people do say if you're going to

fly on wind you gotta put ballast in

you're gonna make a heavy model flies

better and wind not true not true it's

been my experience that heavy models

because they stall at a higher speed or

actually sometimes harder to fly and win

because people will pull back on the

elevator as it speeds up and because

it's a heavy model it stalls a high

speed force out the sky so a nice

lightly loaded model that's flying in a

wind speed which is less than its

maximum speed can be flown quite easily

and it's less likely to have this

problem so don't let people fool you

into thinking that wind fixed the model

once it's in the air there's no effect

whatsoever

now one skill you should have before you

start flying in strong winds is the

ability to fly towards yourself line of

sight

a lot of people you know are not really

comfortable flying towards themselves

they gotta think about which way do I

push the stick to correct it you know

turbulence or whatever you need to be

able to do that without thinking you

need to have that sort of wired into

your brain so keep flying keep flying

keep flying until you don't even have to

think twice about which way to push the

stick when flying toward yourself and

that is because you're gonna have to fly

towards yourself to land it's you can't

get around that you always have to fly

towards yourself to land if you want to

land within close proximity to yourself

so in that respect wind you know

depending on what you've got upstream I

had the houses and the trees you're

gonna have some turbulence even on a

perfectly flat field you're still gonna

have a bit of turbulence and why is that

well it's because here's the ground and

here's the wind and because of the

roughness of the ground you're going to

get a thing called wind here so the the

one near a ground is much slower than

the wind up here the higher you go the

stronger the wind because down here the

ground is slowing it down it's actually

getting dragged from the ground so you

might have might have say 10 kilometres

an hour here you might have 15 here you

might have 20 there so as you come down

the wind speeds gonna drop it's gonna

drop

but what happens here is because you've

got these layers of air sliding you do

tend to end up with

a little bit of rolling turbulence like

this the because this is going faster at

this opportunist to roll around guns

release so you will get turbulence near

the ground

you know generally speaking it's not bad

on in wide open space but you will get

rid of turbulence that means on approach

your model is gonna be wiggly wobbly and

you have to be able to correct that

immediately don't you can't wait and

think now which way do I push that stick

because by the time you've worked that

out it models upside down on the ground

so practice on calm days flying towards

yourself get really used to it mike has

an incredibly valuable skill but

speaking also of this wind shear now

you've got your model flying along you

need to approach with a fair amount of

speed on know I've been airspeed not

ground speed airspeed the model needs to

be flying quite comfortably not right on

the stall because let's imagine your

model stalls at a certain speed and say

you up here

here's your model and if you're flying

it say you're flying it 15 kilometres

above the stall speed right great and

you're looking at it from the ground and

it's moving a certain right let's find

your 20 K of wind blowing over the thing

so you've got five K X s over stall beer

right if the model was even if it was

just sitting motionless as you come down

however the wind speed drops so if your

model is traveling at the same speed

relative to the ground it's actually

flying slower through the year because

the wind is lower sorry I'm facing the

wrong way

this should be the propeller and this

should be the tail the gun that's why

right as you come down the wind drops so

the air speed of your model will drop if

the ground speed remains the same so

expect as you come in for the model to

actually pick up a bit of ground speed

because it's going through

listen list went and if you try and keep

it at the same speed then when you get

to here you may find that suddenly it's

actually below the stall speed and it

will just fall onto the ground again

it's all about judging that difference

between ground speed and air speed

that's just down to practice you just

gonna practice one thing as I said you

are going to have rough landings when

you learn to fly in the wind it's gonna

happen that's why you choose a model

that's robust and resilient like the axe

in or some other similar trainer my FM

is super easy he said so many

topsy-turvy landings and apart from the

occasional broken prop and a bit hot

glue she's good as gold so you gotta

appreciate that don't do this with you

best model don't do it with your $5,000

scales

you know chorus Cal Spitfire some

no choose an old model you can you've

been flying for years and you know how

it flies and then when you dork it when

it ends up no space in the ground you're

not gonna cry about it but you've

learned something along the way so there

you go be aware of the wind shear and

which means as you get close to the

ground you have to speed the model up

relative to the ground to keep it flying

if you try and hold it at the same speed

it could stall and fall on the ground

simple stuff so those are the basic

things to be aware of and that's really

yet when it comes to flying in the wind

just keep your common sense about you

one other issue which I should raises or

just go back or just change

jump cut here we are back at the magic

line scenario winds coming this way is

the magic line what's going to happen at

some stage is you are going to lose

control you're going to make a mistake

and even though you're one mistake

upwind you might make two mistakes in a

row which means the model will suddenly

disappear over your head and be downwind

here right and facing and hitting the

wrong way so it's going downwind at

quite a bit of speed because it's the

flying speed plus the wind speed and so

you're gonna do something then you

couldn't decide what you're gonna do if

you are lucky you'll be able to spin

around turn it round into the wind and

fly back but that doesn't always happen

sometimes you get a bit flustered or the

model it's a gray day and the models

hard to orient and suddenly you realize

things are going wrong it's just going

further and further downwind and it's

getting a smaller and smaller speck in

the distance you have to make a decision

at that stage what do I do most people

unfortunately will fight the model all

the way to the horizon and it will

disappear and you'll never see it again

because you're thinking oh I could just

get it back I can just get it back not

always a wise move I recommend to people

once you can no longer tell which way

the model is going just cut the throttle

and let it land because all you're doing

is increasing the distance you have to

walk and making it harder and harder to

find the model if you can no longer tell

whether it's coming or going you are

never going to fly that model back so

cut your losses put it on the ground so

once the model starts appearing is a

little dumber yeah well before the

improver ibly as far as when it's

further away than you want to walk land

it and even if there just needs cutting

the throttle and getting it glide

whichever works going it's better than

you know having it disappear miles and

miles away

most people who fly and when at some

stage you've lost a model because they

just haven't been able to bring themself

to admit that they can no longer fly

them all it's too far away

important point if you want to keep your

models be prepared to buy Oh be prepared

just to cut the throttle

let it guide which again choice of model

you want a model that's got some

stability if you have a EDF a4 Skyhawk

or something and you cut the throttle

and you can't tell which way it's going

it's going to crash but if you have if

it miss super easy and you cut the

throttle will glide gently to the ground

and again choosing your flying area is

important because as long as there's

just grassy fields there nothing's going

to happen if it's gliding gently onto a

freeway or a motorway but then things

will happen so that's why I say one of

the first things check your flying your

you make sure you're flying in a safe

area there you go I think that's about

it

for what is perhaps a complex subject

but once you get the hang of it trust me

you will look forward to the equinoctial

gales every year because it is some of

the best fun you can have any pants on

it's like the turbulence you're going to

be right on the sticks you've got a

thing and when you do it it's such a

buzz to have flown a model and I've

flown models in in winds which are

possibly only 5 to 10 kilometers now

slower than the maximum speed of the

model so it takes forever to make

doesn't send to the wind then you do

those downwind passers whoa really fast

those the throws you can't get any other

way and it's cheap cheap cheapest model

and you can have a ball of fun in the

relatively small area because sometimes

you can take off you can do an entire

flight without making a turn if the wind

is close to the flying speed of the

model you can back it in for a landing

that's the only time you don't have to

be able to fly towards yourself if the

winds strong enough you can fly upwind

and you can just basically slow the

model down and bring it down and then

descend and land in front of you I've

done that many times it's a real buzz

doing this so there you go that's it

questions comments in the usual place

please I'll do my best to answer them

comments especially because I'd like to

hear what other people have felt about

flying and strong winds do you like it

do you hate it do you just sit out the

equinox or do you really and the

wonderful fun that can be heared from

flying lightweight models in strong

winds there you go thanks for watching

stay tuned bye for now

stay on the grass they don't break a

prop these days inverted takeoffs don't

work Neil

we've tried nice

Tyko frog sounds good

I came in this way
