I agree with jet, and from what I have heard from other people that own one, The third channel is a pain and placed where you can barely get too, and its a momentary on/off meaning you have to hold it in place to work, like reverse. It also isn't set up to accept a battery pack, so soldering would be nessecery. Trigger throw can not be adjusted. I think the big seller is that you would be on your own different frequency. But for the price, its a great deal with 2 recivers.
