Hello all.

Couple friends of mine are building a rookie and we can't seem to agree on how to set up the surfaces.

Here are the options we came up with:
a) Inner and outer CS working together aka. Flaperons.
b) Working seperately. Inner are elevators and outer are ailerons. (my choice)
c) Outer surfaces are ailerons. Both inner and outer work together as elevators.

What do you guys use? What do suggest/think? What are the pos and cons?

Thanks...

I am using one servo per side and running elevons. Not sure if the split setup will work, the elevator work be kind of small.

Erez,

The elevons are two small to use the inner ones only as elevator. You will not get enough pitch response during lower speeds (such as landing flare). The rookie is designed to use the control surfaces as "Elevons" and it flies the best this way. You will find it is very lazy in both pitch and roll at the lower end of the flight envelope using the control surfaces separately.

Hi Todd,


As I understand the surfaces do not move all that much. Couldn't we move the inner surfaces more?


Vincent,

Thanks but I'm scared of loosing a servo and therefore the airplane. 4 servos give you redundancy.


Thanks for the help guys.

I molded the two together and use one servo per side as Vincent did. Actually all of the Rookies that I know of are set up this way. It is powered with a P-120 and has never done anything to make me believe that I should have used two servos on each wing. It just seemed like over kill to have two on each wing.

Todd is correct when he said that it is lazy at lower speeds. I will end up using full up on the elevators just before it touches down.

Erazz,
Just use a good servo in each wing like an 8411 or 5945 and your good to go. I have lots of single servo elevon experience to draw from and never lost a jet due to a servo faliure.Its always something else that bites you in the a** !!

Using 4 of those

O.K. I get the point. We'll use them like flaperons. Thanks.
