i have now decided to buy the Turnigy xk 3674 - 2200 kv [ leopard copy ] going by a reviwe between the leopard and the turnigy on r/c groups, cheaper price, and run the 180 esc plus an abc h7 prop. if i want even more speed i can easily swap motors over to the Turnigy 4074 - 2200 kv. then maybe a neu , what do you think ?
