Finding the CG on a RC Plane

[FesterBable]

I have an easier way of finding the GC: Look at the plans that came with the plane. It is marked on there.

Well I agree a tail heavy plane is the worst to fly and almost impossible to land. I had my 1400mm P-47 way way way too tail heavy on the first flight. The trick I used that kept it in one piece is when you land, land almost completely with throttle control. The reason is that when your plane is tail heavy the elevator will drastically affect the plane. So, if you use throttle, and a tiny tiny amount of elevator, you might be lucky enough to keep it relatively unharmed. not guaranteed but helps.

Hey Antonio

How about on a delta style ing where the thickness is pretty even and flat. I do use KF2 airfoil on my deltas, but always have a hard time finding the CG.

Can you help?

I have a J3 cub 1800mm wingsp. Havent had maiden yet, but will it be an idea to have it a bit nose heavy?

Great vid - very informative.

30% of the wing tip is CG

thumbs up so nitro planes can see

[Lithonion1]

As some stated this is one type of wing and does not apply to all wings. If you want true CG for all types of wings just google CG Calculator for accurate CG.

Swept jet wing... the hard part is finding "MAC"

(won't let me put in link to picture... nsrca org technical tip_tricks mac_cg )

CG will still be appx 30% MAC for conventional (most airplanes) configuration or 15% for Delta or flying wing.

Consider a plane with small horizontal stab, close to the main wing as being a flying wing.

For "canards"... it gets even more complicated

Now can you make a video like this one for swept jet wings?

I looked around for a long time trying to find info on Cg as it related to RC airplanes. Great to have this video out there!

Hey nitrorcx i bought the guanli j3 cub. from a different store but i think they are all the same . anyways i think its a good plane only problem is the motor hasnt got any down and right thrust(offset) to counter the torque from the motor. not a big problem when u hand launch but it wont go straight on the ground. i fixed this by drilling a hole thru a button and using that to make some down and right thrust

[Fryingcows]

@11adijoshi start at about 25 to 30 percent of the mean wing cord

Thanks for the good info.

[easycretor]

It's a good tip thanks Tony. And keep it up.

[Pilotsofer]

Very good video!

[roberttreboranita]

very good video....Gracias Antonio!

[n1tmtu37]

It would've been nice to see various types of wings. The three you displayed are all fairly similar. What about a swept wing or a delta wing, for instance?

[connickjoseph]

Tony, Thanks a lot. I needed that lesson. And keep em coming I need all I can get, Half of all my planes come from Nitro.....Thanks again.....Joe Connick

[SubatomicMD]

Great Video Antonio!!

[anderman72]

Thanks Antonio!!



[ddrlankyj]

the phrase I've always used is "A nose heavy plane may fly poorly, but a tail heavy plane flies once"

[MegaGuitar87]

great tips.

[kdknitro]

just from my pov, not that informative, bes thing you did was hold up the yellow plane and show its cg, first timers wont get whats behind cg'ing a plane

[optimistONE]

Very informative. I like these type of vids because I think sometimes RC flyers overlook CG and the like. I know I did when I first started out. Nicely done!

[bigdoghaveit]

great thanks that helped alot :o)

[rotorwash46]

Thanks tony great tip,happy flyin.

Your not Tony.. Tony's asian! :D

Great new intro :)
