I can't say, enough good things, about Rotorgeeks. I can only add, that in my over 60 odd years of shopping and buying ( around 50 yrs in RC.)
Dave of Rotogeeks was and is the most helpful of any...
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'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....
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...
