I'm glad to here that. I was reading a post the other day where they were talking about putting .60's and larger on smaller planes.. I'm not sure but I think that sometimes you have to use some common sense and say - "hey, that might just rip the plane apart". And like I stated before I have 2 of these with just ST .45 on them and they are plenty fast. I guess my eyes are just not fast enough to watch a 50" orange plane tear through the sky at 150 mph or faster. So I guess I'll enjoy my less than 100 mph racer and hopefully have the wings attached after a few more races around the track. I was flying here sat (even up north it was 60, go figure) but breezy and had a blast with it. It goes verticle far enough and falls over on its back nicley into a smooth power dive...
