Well I am about to start a new project (Skybench Big Bird w/ electric power and flapperons added) and it is time for me to move up from the trusty Futaba Attack 4 AM radio that has served me for more years now than I care to remember. An entry/mid level computer radio seems like a good investment.

Question: it appears that each model and brand I look at has aircraft and helicopter versions, yet they all seem to have the same programming features for each type of aircraft. I see no reason why the H version of a particular radio cannot be used for for AP as well as the AP version. What's the difference?

The reason I ask that in looking at the used market, I need to know whether or not a good used H radio will do just fine for my sailplane, electric and gas flying or not.

Thanks,
Bill
