The gp plane has very small control surfaces. I don't think you could modify the elevators as the hinge line is already very close to the spar tube. The ailerons are very small as well, although they could prolly be modified. The kit is also pretty short compared to other 3d ready planes as you have noticed. I am sure it will make a great imac, or scale flyer, but for all out 3d look for another airframe. I thought about getting one of these as well. As I am sure a lot of others have too, as they are very cheap. I have watched a couple fly, and both looked to fly well, but no 3d was attempted. Also after talking with the guy flying it about it's 3d ability he stated that he would look for another airframe. I am sure it will hover, and TR, but will fall short when you try to harrier, and rolling harrier the plane. Like I said I thought really hard about getting one of these a while back, but I do not think I would be happy with it at all. I still think about it every time I get one of them 50.00 off coupons from tower. as you could buy the kit for 225.00! But I will not be buying one as tempting as it is. Now go back to the CA extra thread, and get you one of them!
