the 1410 is pretty good. why do you want to change it out? I have the tekin sc4x and it is fine, but it lacks the snap power of the 4 pole. So if I dont carry my corner speed some jumps can be harder for me. Otherwise it is fine. The pro4 4000kv seems alright. Nice snap and easier to gear than the 4600. But a few people run the 1410 with great success at my track. Even the heavy losi truck fly with it.
