Q:also how are you attaching the wire to the comm??
A: using a 60 watt soldering iron with silver solder.
Q:are you epoxying the whole arm after it is wound??
A: Havent used epoxy yet, but i do wrap the windings with kevlar thread, just below the communicator. that works well to keep the last winds from going to the outside, or fron being thrown.
Q:are you using fresh blanks or unwrapping wound motors??
A: I was just unwind motors. so far an epic 27t, orion rush 17t, and a peak 17t
Q:if youre unwrapping arms to get blanks how many you wind stay together or dont short and smoke??
A: none so far, i just make sure i take my time, and clean the wire good before soldering. i have noticed alot of brush wear on the epic though im not sure why. maybe it came with softer brushes and wasnt meant for that kinda rpm.
hope this helps.
