I have a Hangar 9 1/5 scale cub with an inverted magnum .61fs. It did not want to idle when inverted but would run at half to full throttle. No amount of needle twisting could sort it out. So to solve this, I built an onboard glow system activated from the throttle servo. This worked but is cumbersome. I then bought a Hobbyking 2 way onboard glow driver. The driver works when pushing the button in manual mode, but does not work on the receiver. I am using a Hitec Optic 6 with a 2.4G module and a Hitec Optima 7 channel receiver. What am I doing wrong? Anybody with experience on these Hobbyking glow drivers?
