Hello to everyone! 

  Has anyone changed or experimented with the 16mm (by the

plans) difference between the outer and inner flaperons as measured at the

trailing edge. I understand that this distance can be adjusted for leveling the

plane side to side, or for hands off flight. What other results could be gained by adjusting the

measurement between the flaperons??

Thanks,...Don B

As I understand it, the purpose of the step between the inboard and outboard 

flapperons is to provide a washout effect during stalls.  If you reduce the step 

then you will reduce the ability to keep the wings level during a stall using 

the flapperons.  Also, the stall might become more abrupt as it will happen over 

the whole wing instead of building from the inboard to outboard.

 there are very few bad ideas in experimental aircraft,but this is one of them,it would rank alongside intentionally being outside you cg.

Thanks, Doug and Mike



  While I currently do not have any flight issues with my plane, I was curious to find if anyone increased or decreased - equally -  away from the factory setting of 16mm. While checking my 701 I found one side slightly less than the other, (previous owner), which did improve hands off flight.

  I was curious if anyone deviated or experimented from the factory settings for what kind of problem and what was their result. Thanks...Don B
