What kind of transmitter do you have or are planning to get? If you are looking at the Parkzone or eFlite plane or heli, then a DX6I, DX7 or DX8 would be fine. The specification for the model would indicate that. I have a DX7 with the BNF Parkzone Corsair and the E300, the eFlite Trojan and E300 Extra 3D. All are easy to bind. They come with DSM2 compatible receivers, and instructions on best settings for the model. Lol at the HorizonHobby web site for information on those and other BNF models.

If you are planning on growing with the hobby, then BNF is the way to go. One transmitter for all models. I made the mistake of buying RTF (ready to fly) models and ended up with 3 transmitters that can't be used for other models because of their limitations. But I never thought I would enjoy the Hobby that much.
