Flite Test - Differential - FLITE TIP

[@dhdsracer]

Remember guys, you can't use differential if you are using a Y-harness on your aileron servos. Thanks for the video!

[@tonyantoniou2853]

Differential is cool but what % more on the up aileron?

[@isoldemarangelis5096]

Great tutorial , always enjoy your humour Joshua.

[@hertzkot]

Excellent video & tutorial, pity about the distracting yawns.

[@kevinjulievan]

love your videos. educational and funny at the same time. my eight year old and i both love them!

[@promitchakraborty]

That's a great video, y'all!

[@Gumby1974]

Bernoulli's principle is what causes this effect. The pressure on the bottom of the wing is higher than on the top (which is what creates lift). This is even more evident on high lift wings with a flat bottom. The aileron that goes down will have more yaw effect because of the greater pressure under the wing. That is why differential is more important on high lift wings.

Hey thanks for the video! I have several RC EPO planes and I am a competent flyer,but I am looking to get into basal and fiberglass. Would you suggest this plane to start? Are the flight characteristics such that I could learn and progress with this plane? I noticed that HK sells it as a kit and I love to build, thanks a bunch.

[@purefantastic]

They're definitely filming at Vasquez Rocks, just north of Los Angeles, CA.

HI Josh x 2, I always enjoy your videos. Thank you for passing on you knowledge and experiences to us. Can you tell me the set up you are using on ths 1.5Mtr Fox? What engine and speed conroller, servos etc. Thanks .

[@aeropoke26]

@vanepico Kind of. a spoiler's job is to purely reduce lift by "spoiling" the airflow over the wing. an aileron works on the principal that it is increasing or decreasing the effective camber of the airfoil/wing section thus increasing or decreasing lift. So the aileron is essentially causing an increase or decrease in circulation around the wing where as a spoiler will merely disturb the Lifting pressure on the upper surface of a wing. I hope this helps.

[@bongose]

like the real deal! keep it up guys, great work!

[@dennisrkb]

Is this just to counter adverse yaw, or to ensure the plane is strictly rolling around the fuselage also?

[@belro17]

@dhdsracer You can set mechanical differential though by putting the arms slightly forward or back on the splines

[@vanepico]

@aeropoke26 Thanks for the very indepth reply, i didn't think of that! so the upward aileron works like a spoiler, reducing the lift of the aerofoil reducing the drag, you learn something new every day!

[@aeropoke26]

@vanepico This phenomenon occurs because Drag is proportional to Lift. This is called induced drag CD=CL^2/(Pi*AspectRatio*efficiencyfactor). when you deflect an aileron down it creates lift thus creating more drag. Because there is more drag on one wing than the other, the plane will tend to yaw.

[@NzAviator]

@vanepico its because the downward aileron is is causing more camber on the wing therefore increasing lift. and an adverse effect of lift is drag. hope this helps

[@TwilightCompunction]

FPV in that terrain would be fantastic.

[@MarioBotelho]

I believe it is missing details for mechanical instalation, we also can have the diferential action mechanical with one servo or two servos with Y extension, just need to shift the position of the links on the servo arms, I mean installing the link like 30 degrees shifted from the servo central position.

[@what_on_arth]

Doesn't the drag act on both the ailerons ? Shouldn't the moments cancel out ?

[@kevinsraydatme]

great.. now I know what they are. any chance you can show how to program on Taranis?

[@TakeshiM]

how much time was actually between the shooting of this video and the one where the fox crashed?

[@RichieMann5275]

were are they filming?

[@tbvdb]

wohoo new flite test!

[@austntexan]

The good ole' days.

[@FreddieKerner]

great vid!

[@MichaelEllisOfTenDeg]

So we still don't get to see the Fox fly? I mean without annihilation after 2 seconds... ;-)

[@NeroAD64]

Bless his heart, Ya'll

[@chrish3witt35]

flitetest and djmedic are the only rc channels to watch!

[@vanepico]

why does it produce more drag when it is downward?

[@GaryJLoder]

What happened to Scott Joshua ?

[@shelviahall]

Loved the yawn, y'all. Great video! :)

[@jandirks]

One thing that should be mentioned, probably, is that your need 2 servo's to achieve differential. Maybe obvious for most of you, but not for all.

[@wordreet]

I think I had Bernoullis the other night. Ah no, they were Burritos. What flavour are Bernoullis? A side order of Rogallos could be good too. ;¬)

[@jay37010]

what kind of plane is that!?!?!?!

[@sheko2000]

is that affects rolling ????

[@salvadori007]

This model also has an angle in elevator, that is probably wrong... when you decrease the attack angle of elevator(3 to 5 degrees), the flight become a lot more easy and pleasant...

[@BaDlYbRUiZeD]

lmao Scott, men you said differential with perfect Portuguese accent lol you would blend in perfect in Lisbon talking like that! :-D

[@RosesForTheDead7]

What plane is this.. is want one..

[@blueguy12345]

here is one Josh to many in your videos...

[@MrSpectacularMan]

the description says southern california

[@Danielaragon1251]

Somewhere in Utah, I think.

[@rcsuperflite]

The bixler!

[@FPVSpace]

Wait so you have a hot liner/glider, on a windy day on a big hill, and you DONT want to fly it? That is the exact place to be flying it, catch some sick hill lift.

[@fantasiiio]

@lbchuma Some airplanes doesn't have rudder.

[@MrCpuclocker]

Did anyone notice that in the intro at 0:15 his finger is scarred.

[@PHeMoX]

Beware that borderline hotliner!

[@RoboTekno]

"Differen-sial!" ^_^

[@youtwoba]

Should have tossed it! :0)

[@sundown798]

@MrCpuclocker and?

[@qiangchen4417]

Differensy’all

[@falconeaterf15]

You should have a hot girl in a bikini eating bananas in the background.

[@billstewart5421]

Les intro more subject

[@Rocketryman]

Do you know what this video is missing???? A reach around.

[@lbchuma]

why not just learn how to use the rudder?

[@johnkennedyk522]

why does it have to be southern ?lol

[@Canoodlan]

Davis windesTIAL!

[@wordreet]

No flying in this videoi y'all.

[@MrCpuclocker]

My bad Between 0:14 and 0:15

[@AxelTiger]

That prop looks very sad...

[@i0.0t]

19,006th!!!!!!!

[@Isthatafactnoitisnot]

18,843th!

[@Airomaster121]

NO NO DONT THROW IT!

[@TomReed95]

[@Woski27]

Please ignore ritzerinaustralia, he makes Australians look like assholes but in fact most of us aren't. By the name I'd say he's German anyway, which should make him more gay tolerant. The vies are amazing, I just wish I had of thought of it first.
