hi,getting back to the bulldog thread,i maidened mine yesterday.first flight was a nightmare as it did not want to rotate on takeoff.once off the ground i was holding in about half elevator to keep it level.managed one curcuit and landed.i had set the c of g to around 70mm to be safe!! lesson learnt.i then reset the c of g to 75mm and it flew better but i think it could still bite the unwary especially on steep turns.(it flicks quite badly if you pull full elevator)i now plan on putting the c of g to the recommended 80mm so will get back here when i ve flown it again.
