I soldered the esc leads direct to the motor with thick gauge wire and changed my battery to esc connectors for TRXs I ran down to a 8turn motor with very little heat on a 9.6v pack its a small size esc too so you can move it outround that tight chassis to help stop interference.

Or just spend a lttle more and grab one of those EZERUN bl system from ebay for around £70 that way your not spending loads on replacing brushes every 10 or so runs,i went through a load on that 8t every 5-7 runs i noticed the performance drop even on 7cells[]
