Do NOT get the 2.4, you will regret it if you want more than 2 planes an rx is $100, go with 72mhz and you can get rx's for $35, My tx went whacko so I got the newest 2.4 for too much and regretted it, traded a friend a model he wanted for his tx and had to have the channel changed ...another $90!!......dont get it...Rog
