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...
If you live in Canada, this is the best place! Super fast shipping compare to any popular US store and no duty bill!
RotorGeeks is my go-to for just about everything FPV. Their RG20 ESCs and PZ600 mini FPV cams are probably the best on the market of their sorts. Customer service is great, I've left goofy comments in...
Great guy and very helpful ,+ he has all the good stuff and he is in Canada
Communicate really fast when you did a mistake in your order. Fast shipping. Open a package is always a pleasure :) great gift every time (stickers and straps).
