I will be flying Spectrum. It is working flawlessly for all pilots using it in the local clubs I belong to. Not only that, the 'feel' of the control is remarkable. Gone is the 'jerky' proportional movement of the servos. It is more like the cable feel of a full scale. More positive, instantainious control than we have ever had. Add to that, that nothing on board the aircraft can interfear with it, which makes it a perfect choice for controlling gas and electric aircraft, IMO.
