DO NOT run brushless motors at full throttle with no load. It will cause them to over rev and heat up very quickly - as you know. That spark is caused when the capacitors on the controller charge when you plug the batteries in, its nothing to worry about. Still makes me jump every time it happens though :rolleyes:
OO, thanks for the info!
Won't do that anymore.
OK, then maybe I don't have an issue. :010:
Thank you for the information. I feel much better now. :027:
