<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> I would like to talk with anyone using a trim tab on the ailerons due to a  wing heavy condition on a CH-701. I've tried twisting the wing via wing struts,  checked rigging, slats all within required tolerances. The trim tab seems to be  the only option left unless one of the 701 Guru's can come up with another  option, thanks

Roger,

      If you mean  a adjustable trim tab why not try just a piece of aluminum riveted to the  trailing edge of the aileron on the low wing and put a little bend in it.   If that's not enough bend it a little more after each flight.  Of course if  you carry a passenger you would need an adjustable trim tab.  I was warned  that my XL might need aileron trim so I am going to install an adjustable as I  build

I changed the bungee on the elevator cable to the other cable and that cleared up my left wing heavy condition, simple fix.

Hello Roger,



My 701 flys hand off once in cruise,  is a little heavy to a side only at power (climb) given the engine torque.



In your plane has to be something with  the rigging or the assemble  of the wings...   

I note in your address that is a Savannah... Probably is the same or very similar construction in the wings as the 701, given is a pirate copy of the 701.



Start with the most easy:  messurements of the wings with the fusselage perfectly level.  and the stabilator level also with the fuselage.



Then find a way to see if the wings are not twisted when assembly, I dont know how to do it installed...  This is checked in the assemble table before installed in the fusselage.



Depends the amount of  "heavyness"  of the wing when flying, is how dangerous could be to continue fly it now the way it is. 



Saludos

I think you will find that rather than add a trim tab the  prefered method is to bend the trailing edge of the aileron  for roll  wing heavy'

 a similar fix for pitch trim is adjust the trailing  edge of the elevator
