I know what you are saying. I already did the math but I just don't feel like pushing these motors too hard since no rebuild kits are available. I would hate for one of the rotors to let go and then it become a fancy paper weight.

I have already tried the 1520 on 8S for about a minute and it was awesome but I didn't want to wind it out anywhere near it's full speed. Also ran the 1717 on 8S too for couple of packs but that was crazier than two story outhouse. I just wish I could get rebuild kits for them so if something was to go wrong then I could rebuild them.
