Yeah, 3000 kv is the top as far as 3s is concerned. Good points SKelly, thank you for giving it a go. I just picked up a DESC10, and you can bet I want a 3s system in this. I will run 2s for awhile, but nagging all the way(think Christmas carol.) The DESC10 and Teknos beg for a 3s system. I see carpet tracks in the same league as indoor tracks. You don't run 4s buggies either, so why bother us with this. We are mainly concerned with outdoor tracks that also run 4s buggies.
