Awsome Motors, no question about it!
8x2 last me about 7-10 runs before I even open it up.
10x1 last me about 12 runs before I took it out from my Yokomo SD and put back right in my 1:12 scale and ran for 5 packs and it still in there. Will be running the same comm, brushes again this weekend.
When they said Enduro brushes will last about 10~30 runs... They really mean it!
