I am building an ULTRA at the moment and I have the following questions...


1. If I install the flap servos per the manual ( written for the classic lightning) The output arms hit the underside of the top of the wings HOWEVER If I mount them so the output arms point towards the wing bottom they fit better. IS this the correct way for the ULTRA?
2. The CG method in the manual says it is 45-50 mm in front of the center of the spar tube with the wings off, with the fuse balanced on the spar.. IS this OK for the Ultra version? THANKS
