I have a Graupner MZ16 and a MZ24 I want to use a Gyro in two of my scale planes. And the Igyro1e and Igyro3e come highly recommended. But I am not sure if they will work with my Graupner radio. They say the they have and signal input PWM. Is that compatible with my radios. I know the Igyro SRS works with the Graupner radio's but that's a lot more gyro than I really need. Any help you could provide would be greatly appreciated Thanks for your time
