You might want to check some reviews on FlySky radios. I understand they are not bringing rave reviews. Two brands that you might also want to check out are FrSky (not to be confused with FlySky) and Tactic, both of which have better reviews, I believe. I don't have personal experience with any of them so check it out before taking this as gospel. One of the radios that I use a lot is Futaba 7C which I would highly recommend and can be bought used on Ebay or RCG for $100 to $150 for a 2.4 version and less for a 72 Mhz version. If you were to buy a used 7C (or any Futaba) in 72 Mhz, you could then buy a crystal for the receiver already in the plane that matches the transmitter. If you chose a 2.4 Ghz system and it did not come with a receiver, you can purchase a FrSky FASST compatible receiver for less than $25.00. I presently have about 15 or so of these receivers and have never had a glitch with any of them, FrSky is making good stuff.
