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...
Easy to communicate with and provides excellent customer service. One of my parts had a factory defect and they had a replacement on the way the next day. They've earned my long term business.
I really can't thank the guys at Rotorgeeks enough. Well it seems that I can with money (haha!), but in exchange for that money I got service, patience, and most surprisingly excitement. I don't know ...
Awesome shipping. Great products. Great Prices.. RG20 ESCs are the best, I'll will be using them on all my builds from here on!
Amazing customer service even help out on closed day when in the shop amazing, they just want you flying.
