I bought some EDF-40H fans for my hummingbird elite because all other motors kept on burning out. I'm having a little bit of trouble figuring out how to install the damn thing.. I've drilled a hole in the EDF and slotted the tail boom through, CAing it to the motor heatsink and the small bit of the boom which touches the casing of the EDF.... VERY VERY flimsy.... It's okay for hovering, but I feel that if I put any more rudder into the heli, the EDF will fling off the tail boom..

Any suggestions? I bought the EDF carbon tail and fin set from the net, but that's only for looks, it doesn't actually support the EDF. Is there a mounting tool I can use? Any procedures I should do?

Any help would be much appreciated.

Thanks
