Flysky FS-i6X 10 Channels RC Transmitter and Receiver FS-iA10B 2.4GHz AFHDS 2A Radio Control System for FPV Drone Quadrotor, Fixed Wing, RC Car and Boat (Mode 2 Left-Hand Throttle) Black

Works great. Easy to program once you download the full manual. Very efficient on the batteries. Great distance handling.

Excellent RC Transmitter and Receiver for entry level enthusiasts with up to 10 channels, and programming for up to 20 different RC vehicles, and very affordable price.

There are cheaper radios on the market but they are trash. This is feature filled and up to 10 channels. I really love these flyskys and have 2 of them. I also buy the 4 channel receivers on AliExpress for $4 for my small flite test planes. One downside to this radio that could be a big bummer for those building larger or more complicated planes is that you are limited to something like 3 mixes. But if you are able to afford a more complicated plane than you definitely should be able to afford a more expensive radio.

Great controller! Easy to use and works Great! Would love to test out one of the higher end models

I've used this for planes, trucks, tanks, and even FRC robots! The ten channels work amazingly for anything you need to control, and the reciever can easily be powered from the ESC of the model you're operating, though more complex models may need a voltage regulator to power it.
