BuddyRC is always a pleasure to do business with!

Very nice radio. I'm coming from years of Spektrum DX6i and DX6 and the 10 additional channels are awesome for like $100 less! It's taking me some time to get used to the new user interface, but it seems very capable. I've just not been able to spend much time with it. I did get two of my quads setup and bound to it and have no complaints at all :) It's about 1/2" narrower than the DX6/DX6i, meaning the sticks are about 1/2" closer to each other in the X direction if that matters to anyone.

I ordered 4 of these little receivers and they look great. I'll probably order more. They came packaged very well and was shipped out super fast!!!
