I am in the process of putting one together. A couple of the guys at my field also have one and the problems they had were that they put in brushless motors and tried to make hotliners out of them. They learned the hard way that the wing needs to be pinned in at the leading edge, they both had the wing pop out of the fuse. One of the guys got another one and after gluing the wing together and attaching it to the fuse he then drilled thru the securing mount and then glued a carbon rod in the wing so that it would then be secured in the fuse even in a strong dive pull out.

BTW I got a chance to fly his today. It has two HS 56's in the wing and this one only has one servo for the tail ( he noticed that using rudder on this bird tended to slow it way down and that was a problem), while it still has the brushless motor and a 3s1p battery I think that my bird with the four servos and a 2s1p battery wil be about the same weight and the speed in a thermal will have to be watched for.

I was handed the bird at a pretty good altitude and after about ten mins later I used the throttle for the first time to climb back up to altitude. I did notice that it would tend to spiral fairly easy, but with, for me, a change from the way I fly floaters to this bird that needs the speed to stay up it was not real hard to gain altitude. I was not trying to core thermals as much as figure eighting across the front of the wind and then doing some fairly big circles in lift.

I had been a little lax on wanting to finish this bird until I go to fly this one today and I am not ready to go for it.

I also think that I will have to get some color on this transparent yellow bird, for visibility at altitude, maybe some sky shine.
