RE: Twist broke in half...pictures at 1100...
I would not plane the plane on this. I have one and I have well over 150 flights on it and have a few hard bounces . Not once has my plane broken like this. The worst was ripping out the gear and that was only once. I know of too others that were way over powered (Saito 100's on both with 14x8 props) and the worst was loosening the firewall.
I am puzzled as to why you would hand launch a Twist.
Larger diameter, less pitch = more pull
smaller diameter, more pitch = faster speed
As with most ARF's, you get good ones and bad ones. I have a Funtana90 that I had to repair/reinforce every rib on both wings. I did it myself since the wings are on back order for 3 months.
