I ordered a new airplane tonight , at $119 its not a bad price . I'm not upset about the crash only the fact that I dont understand why it happend. I would have gone full throttle going down the runway but it was traveling at quite a good speed to begin with. It was moving faster than the 40 would move it but yet it winged over. I am going to install a super tigre 51 on the new one this week and see what that one does. Im just a little leary of putting the 72 back on the new one since it torqued over 2 times in a row with the second crash being the killer of the 2. I dont believe takeoff speed is a issue here but more of a torque issue once the airplane gains altitude. I have other planes in my hanger that have no issues and no flight problems running 4 strokes and 2 strokes alike. Everything from the rascal 110" to the Agwagon and Giant stuka. I even overpowered my T34 mentor and it never rolls like this one. Im trying to get some info because I have the 1/4 scale GP spacewalker and I dont want to make this mistake with the bigger more expensive one.
