Excellent thanks I will join in on that thread 2, well I am new to rc and electrics is a whole new world for me lol I do, do my research tho but also rushing a bit lol cuz wana use it, I brought it second hand but later realised it had a 4800kv smaller boat motor and cheap 120esc and overheang issues, long story short after a few spurs the esc caught fire, lucky to have fire estiquisher lol.. I have 32dp 49t hardened spur ready and ordered 15,17,19 hardened pinions to try different gearing, also it said on website 2s-4s lipo..but Manuel's say esc can handle 4s but the motor Manuel says only 2s and 3s so I was planning on running 3s also.. thanks
