Not sure if this is a true "how to" but I guess the info may be useful. Fisrt time I have done this, so not sure if it is the correct way or not. Here we go.
So I decided to wrap the magnet of my hacker b50 5s motor with kevlar thread. I will be using this motor on 3s lipo in my speed 10th scale, so magnet reinforcement seems like a good idea.
I scoured ebay for kevlar thread and found some. The seller also had something called vectran, which is supposed to be superior to kevlar, so I bought it.
Heres the link :

When I received the package today I had a look and the vectran is thinner than the kevlar, so I decided to use it as the air gap between the magnet and winding is tight on the b50 motor.
Heres a pic of the rotor before:
Heres a pic of my supplies, 30min epoxy, 80 grit sandpaper, vectran thread, shrink tubing, and paint stick:
Rotor after light sanding:
Rotor after application of mixed epoxy and wrap of vectran, I wrapped it as evenly as possible, but the vectran is very fine, and not woven together so it was difficult to make it overlap much:
Heatshrink applied over rotor and heated up to hopefully hold it all together while drying. Also hoping it forces out any excess epoxy.
I will cut the heatshrink off tomorrow and see how it looks. I will also balance the rotor, not really sure how to do that, may have to sand some of the epoxy off...
