It is 100% compatible with Turobrix systems. AJ
I was sort of suspecting that it might be. The transmitters look a lot alike, same case with different stickers, and both use a 6 channel receiver.
What might be interesting is if the 4 channel HobbyKing transmitter can be programmed or not like the Turborix transmitter. Not sure if it is worth the effort or not, but what the heck.
