RE: 2.4 GHz... Will one transmitter work with other brand recievers?
It is important get a good Warranty and good Service when you buy a Radio. If you have a problem with your radio and the manufacturer Repairs or Replaces it, that is worth the extra bucks. There are a variety of reputable RC Radio manufacturers to choose from. If you go too cheap, you may regret it.
I do not like crashing any airplane, even the foam ones. I want a radio that is Reliable, Feels good in my hands, and has the features I like.
