I run the 2.5D on 5S and it would still have plenty of power on 4S. Next time I get batteries I will be trying it out with 4S. Alot of people on here run it with either 4S or 5S. Are you looking at getting the Neu or Tekno motor?
Motor and batteries is the only thing I like to buy, just want to get the right things first. But want to go with Neu or Tekno Neu, is there a difference in these 2 motors?---Jerry
