The DX7 appears to be based on the newly released JR 7202 which is a midrange airplane/heli radio with no specific sailplane programming. The Hitec Optic 6, in this same class, has much more sailplane programming, by comparison.
As far as I can tell, neither would be able to handle a 4 servo wing. So I would not expect the Spectrum DX7 to be able to handle a 4 servo wing or have any sailplane specific programming. Hitec is coming out with a plug in module for the Hitec Prism, Optic 6 and the Eclipse 7. They say they will also qualify it in the Futaba 9C and 9C Super. So I will wait for that to turn my 9C into a 2.4 GHz radio. :-) Best Regards, Ed Anderson RCSE-List facilities provided by Model Airplane News.
