"Wing bolts are usually a much better, gives you a no worry solution. The wing never has to come off anyway on these small planes, just put a charging cable for the battery."
True, but if they take a hard knock, something breaks.
"With rubber bands you have to use several of them, and make sure that they are fresh. At high g-forces there is always the risk of the wing moving a little and giving you a sudden change of angles..."
There would be an alignment dowel up front at the LE, so it's not going to move.
I still haven't decided on what engine to use. The MP D , or Cox .049, would be ok with rubber bands, but for the Webra 1.8 speedy, maybe bolts all the way around.
