Yes these true 2.4 ghz radios are so cheap I am not sure why people stay with the proprietary factory radios, when you can buy a full featured radio for less.
Tell you the truth I like the plain and simple futaba skysport. I've seen too many people on the sidelines of a battle trying to remember what endpoints, throw %, rate, etc they need to get up and going.
I do have a DX8 for all my aerial toys so not scared of programmable radio's, just don't see the need on a tank.
