You sound like a man after my own heart Phil. Once I have everything is working perfectly I get bored and have to find stuff to tweak and upgrade. My new project related to the 700X is to rewind the already stupidly powerful Align BL850MX motor. When I got my spare airframe it came with another BL850MX installed. I'd assumed that the motor like the airframe was new but the seller conveniently forgot to tell me that the motor had been transferred from his previous trex 700L. It's actually in excellent condition apart from the shaft which looks like someone has taken a Dremel to for some reason
The shafts aren't expensive but do require an Arbor Press to remove, so I used the excuse to buy both the shaft and the press! Application of brute force and ignorance successfully removed the shaft.
Then I got to thinking that while I had the motor apart I might have a go at the mystical art of brushless motor re-winding
So that involved buying some 1.5mm copper magnet wire and other bits and bobs. I've re-wound smaller motors before but 1.5mm wire is hard to bend and I discovered needs some specialist tools to get tightly wound on the stator, so I've ordered those too.
Anyway, at the moment the motor is broken down to it's component parts, original copper windings removed and awaiting the special tools so I can start winding it again with the 1.5mm wire:
The jury is out on if I can ever get it working again but the attempt will keep me out of mischief for a little while.
