I don't fly anything under about 10:1, so I don't have data on that. 3:1 seems really low though. Scary low. YMMV, but I wouldn't expect any problems aside from some black soot on the lower bracket.Have you ever flown any rockets with a low thrust / weight ratio, say 3:1 or 4:1, where the tower would be subjected to the heat for a longer time ?
Has anybody ever cloned one of the trussed towers like in Stine's book? Those looked so awesome that I really want to build one but I realize it would be a lot of work.
