It didn't crack the frame because every place that cracks is already cracked I have a new frame but decided to try 3d with the busted one. I have a piece of carbon fiber in the same place you have your blocks. What I overlooked was the fact that the lipo tray can bend up now that its broken. That's how the top of the lipo got against the motor. At least I learned something from this and have a solution that involves a slight rerouting of your wire mod. It'll now hold the tray from going up or down. I found that the wires coming out of the Telebee are bare. I'm going to shorten the wires and replace the remote gain wire while I'm at it. Then I'll use some hot glue to reinforce this stress point. Damn, think I'll have a beer.
