What? What does a Kadet Senior with a turbine and glow engine have anything to do with the subject of the opening poster?
To the opening poster, Aladinbama, if the old Hitec radio works and you've tested it with a good range check and it has a new battery, use it. My Hitec Flash 5 that I've been using for 15 years, works fine. Just used it last Wednesday. If you just need a new radio, I'd suggest a Spektrum DX6i. I've got one and it works great, and it wasn't too expensive. Turbine? I'd pass on that. Succinct!
