You can either use a receiver that delivers a single-pulse-train signal (buy one or convert an existing receiver), or you can use a thing called “Rec-Enc” (, that generates a single-pulse-train signal out of any standard receiver. I noticed that there seem to be many definitions of the expression "single pulse train". If you are not sure about this, or if you would like to avoid potential problems, use a Rec-Enc. Using a Rec-Enc might result in a short time delay between your commands on the transmitter and the reaction of the tricopter.
