hi guys,
the reason one surface moves for than the other is down to the wood not being strong enough to handle the the emuff from the servo,also when using the down to align two elevator halfs is never a good idea,BUT, THE MODEL DOES FLY GREAT AND I HAVE WRUNG IT OUT AND IT ALL STAYS TOGETHER,AND EVEN IN THE HARRIER THE MODEL COMES DOWN DEAD STRAIGHT AND DOES NOT FALL EITHER WAY WHICH IT SHOULD,DUE TO ONE SURFACE MOVING MORE THAN THE OTHER!!.SO YES EVERY ONE IS CORRECT IN WHAT THEY ARE SAYING!!.but if i where to have another one out the box i would change and have two servos on the elevator and place the rudder in a alternative postion.GO ENJOY AND DECIDE FOR YOURSELF!!.THE PROOF IS IN THE FLYING AND NOT MOANING!!! LOL.

REGARDS
STEVE
