I'm sorry for your loss.

I saved the plane. Motor just lost power/magnetism due to heat. Oh and the solder on the plugs melted(!).
I knew it was just a question of time before it could not stand up to the increasing abuse anymore, but as I have a identical replacement motor (with a bent shaft from a unfortunate landing - just need to swap the shafts now) I wanted to see how far it would go.

I just upgraded from the standard FJ to the ultra, and I'm wondering if I should order a cheapo hobbyking 36mm inrunner just to test it. If all is OK I can always exchange it with a better one...
