Hello, I purchased the combination TX/RX, and i found that i could not use the GR-18 for fixed wing aircraft. no documentation helped, and everything I experimented with was unhelpful. At one point I managed to make my motor turn on with the pitch control by accident. I was wondering if there was any way to connect the GR-18 to a fixed wing (Simple Storch) or if there was another type of receiver i could use with my existing MZ-12. Thank you.
