What about the for sale column here or Ebay. Could pick up a nice T6xas or something that hold multiple planes. If price is a factor, going cheap now could cost you later. You get a basic six channel but what do you do when you start acquiring a hangar full.
* Make an attempt on a computer radio which holds several planes. If all your planes are on the same channel as mine (9planes) If something goes wrong, I can rake out a receiver from another plane for an immediate fix, and replace it later.
