I got the rotorgeeks 12A ESCs (v4) and they work flawlessly on my 4S quad. I didn't even have to calibrate them. Hit the mark right off the bat.
Service and delivery from Canada to Massachusetts...
THIS GUY KNOWS IT ALL....REALLY!!! IF NOT HE WILL FIND OUT
David has great customer service, always includes stickers and few times I got a free lipo alarm. Fast shipping and great products make rotorgeeks my go to outlet for all my gear.
Thanks David
Great service is the main thing. They even sent me a tiny e clip for free, to JAPAN! I think the postage was more than the clip.
Great guys to deal with, purchased a few items for pickup and generally can order in the morning and pick up that afternoon. Good pricing for quality equipment.
