I ordered the wrong item and requested a change. They emailed me promptly with detailed instructions and voila! Bobs your uncle ;3)
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...
I'm in the process of assembling my first quad. RG has been my one stop shop for my parts: they are always well stocked, great prices, extremely fast shipping and most importantly offer great support....
Dave has always shipped faster than any other supplier, has great gear and provides the best customer service. I've moved to pretty much only buying gear from him and his shop.
Super helpful and very friendly. I just recently joined the hobby and they helped answer a lot of my questions. I purchased a BNF drone and they even helped install a self-powered buzzer on it.
