Hello ! My name is Ray I'm fairly new to the hobby....Have thought about trying to build and fly for several years.Finaly took the plunge ! What a rush to see something you put together actually fly! Well here's the question I have, I'm looking to up grade my radio, my old FUTABA Conquest is not going to cut it any more. If I purchase a new one how many channels do you recomend (looking to be in this hobby for years to come) and can I use my old receiver in conjunction with the new radio (freq. #46).Any help is appreciated.
