I have been fighting with the flap actuator motor on my XL and come 

up with a strange set of design conflicts.  The deflection called for 

on sheet 6-S-3 calls for 30 degrees maximum deflection, but the 

design shown on 6-B-19 can only produce about 20 degrees of deflection.



I spoke to Caleb at ZAC today and he promised to look into this issue 

and get back to me.  I also wanted to ask list members if anyone has 

run into this problem already.  What flap deflection have builders 

who finished their XLs  get?  A related question (according to Caleb) 

is whether the elevator trim can neutralize the pitch changes with full flaps.



I would appreciate any information related to XL flap deflection.



Thanks,



Paul

Mine deflect about 27º and I can't trim out the plane with full flaps.

Do you have the elevator trim tab that spans half or all of the elevator

side? Michael Heintz told me that they went to the full width trim tab to

meet a SLSA requirement of being to able trim with full flaps.
