BTW the 20" upper wing tube will work! I measured mine last night and it is 20". I then measured where the hardwood blocks were it was no problem. So I went ahead and drilled and mounted everything last night. I will be flying mine tomorrow on the 3rd with a new DA-50. I 'm really excited about it. I put JR 9411 servos in the wings, a 8611 pull-pull on the rudder and 2 8411 servos for the elevators, and a JR 770 pcm mini reciever. Also using Smart-Fly switches and regulators with Fromeco 4400 mah Li-Ion batteries. I will also post some pics over the weekend.

P.S. in the instructions it said that you were to measure in over 9 inches to drill the wing tube bolts. That is an error. I measured in 8 3/8". It is not in the middle of the hardwood block, but is in more than enough. I even counter bored the block so that the wing bolt sits down flush.
