At the moment, Hitec does not sell 2.4 Ghz equipment, so you cannot use a Hitec receiver with a 2.4 Ghz since they are not operating on the same frequencies.

I bet some people would tell you not to use those Tenergy batteries because of their low-price, but I've been using those exact same batteries in 2 of my planes with hundreds of flights total (for both of the planes) and they work fine.
