Look up the Jumper T16 - it’s a multiprotocol transmitter that supports most of the major brands, which means you’re not tied into any brand receiver.

The Jumper T176 is amazing, if you're going to get a good TX you want to last you a while, get that. If you want a cheap, small one with not too many capabilities but that a child can use, get one of the cheaper FlySky ones.
