Hi Simon, I had similar problem a few months ago, I broke the RH front arm, internal accident. hit the wall and she dropped onto the corner, broke the carbon fibre tube quite cleanly and two props too. No other damage, so I did a temp repair, external splint, made from a large clear nylon hypodermic syringe tube, I cut a slit long ways and I cut the end cap/tube off, it was undersize and quite grippy/springy, so it held ok, but to be sure I used a couple of lightweight jubilee type clamps, the test flight was as normal, level and stable, and the repair was hardly noticeable, so I then purchased a piece of carbon fibre the exact size to fit internally, it meant taking the motor off and undoing a few wires, only one wire (gps signal) needed unsoldering, I fixed the new tube in with epoxy adhesive (very small amount) and assembled. Perfect repair, only noticeable on very close scrutiny, I know I will maybe void warranty, and my mishap was pilot error, so I think I must have saved £400 and not lost my Bad Bird! That was a few months ago, she till behaves herself, and so do I, nothing teaches like a mishap, I've got some CF Tube left over, who knows I may need more one day ........regards stu. Lincoln
