A lot of work is done.
Cleaned all stators. Removed all stock windings. All bells, with the exception of five of them, had stock magnet rings and glue residue removed. Five stator are wound with 0.35 and 0.4 mm copper enameled wire.
All ready for new magnets.
Surfing the web for DIY ESC project. Got two of them, with board layouts and controller software. Unfortunately, the only shop which makes custom boards refused to build mine, for low number of boards. The minimum is 20. Will try another approach with them.
If it fails, I'll buy a cheap one just to test my motors, and build mine, again in DIY.
While waiting for magnets, I'll try tu build first trainer, a Blue Baby 42.
