Flite Test - Differential - FLITE TIP

[@isoldemarangelis5096]

Great tutorial , always enjoy your humour Joshua.

[@dhdsracer]

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

[@hertzkot]

Excellent video & tutorial, pity about the distracting yawns.

[@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.

[@tonyantoniou2853]

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

[@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.

[@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!

[@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

[@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.

[@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.

[@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!

[@dennisrkb]

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

[@nordicskier93]

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.

[@shelviahall]

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

[@belro17]

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

[@purefantastic]

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

[@bongose]

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

[@TwilightCompunction]

FPV in that terrain would be fantastic.

[@what_on_arth]

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

[@chrish3witt35]

flitetest and djmedic are the only rc channels to watch!

[@grahamlwilson]

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 .

[@austntexan]

The good ole' days.

[@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?

[@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...

[@sheko2000]

is that affects rolling ????

[@RichieMann5275]

were are they filming?

[@FreddieKerner]

great vid!

[@vanepico]

why does it produce more drag when it is downward?

[@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.

[@tbvdb]

wohoo new flite test!

[@NeroAD64]

Bless his heart, Ya'll

[@MichaelEllisOfTenDeg]

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

[@blueguy12345]

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

[@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. ;¬)

[@RosesForTheDead7]

What plane is this.. is want one..

[@GaryJLoder]

What happened to Scott Joshua ?

[@Danielaragon1251]

Somewhere in Utah, I think.

[@jay37010]

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

[@BaDlYbRUiZeD]

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

[@MrSpectacularMan]

the description says southern california

[@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.

[@MrCpuclocker]

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

[@rcsuperflite]

The bixler!

[@PHeMoX]

Beware that borderline hotliner!

[@fantasiiio]

@lbchuma Some airplanes doesn't have rudder.

[@RoboTekno]

"Differen-sial!" ^_^

[@sundown798]

@MrCpuclocker and?

[@youtwoba]

Should have tossed it! :0)

[@qiangchen4417]

Differensy’all

[@billstewart5421]

Les intro more subject

[@Airomaster121]

NO NO DONT THROW IT!

[@Rocketryman]

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

[@Canoodlan]

Davis windesTIAL!

[@MrCpuclocker]

My bad Between 0:14 and 0:15

[@lbchuma]

why not just learn how to use the rudder?

[@AxelTiger]

That prop looks very sad...

[@wordreet]

No flying in this videoi y'all.

[@Isthatafactnoitisnot]

18,843th!

[@johnkennedyk522]

why does it have to be southern ?lol

[@falconeaterf15]

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

[@i0.0t]

19,006th!!!!!!!

[@TomReed95]

19582th

[@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.
