This is the transmitter and a typical receiver with shrink applied. The three pins plug into your electronic timer like the eMAX using the pigtail wire that is normally ordered with the timer when RDT is used.
This is the charge cable for the LiPo battery in the transmitter. You use this with your standard LiPo charger set for a 1S battery and 0.2 A charge rate. The three pins plug into a socket on the side of the transmitter.
This is a Velcro wrist strap I use on my transmitter. Keeps the transmitter handy, yet out of the way. Prevents accidentally pressing the RDT button. I can do this for you if requested. Cost is $15.00
