im running the kyosho 46t spur/15t p with a CC 2200kv on 6s I think its geared for around 65mph. I could easily put a 12t pinion on there. I had to put 2 shims on the rcm mount side bearing to move the spur out a tad and its perfect. Run 8 packs through it jumping off skate ramps and general wheelies and flipping and high speed chases through parks and neighborhoods, nothings broken..... yet.. though I did thermal my Monster lastnight driving wot in grass for 25 minutes last evening.
