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?

I dont know BUT does reversing the servo /switch do anything ? Also try messing with the end points to see if that dose anything . I seem to recall reading similar issues with other people . Let us know if u get it worked out as I have one as well . I just reread your post and I wonder if you could mix it with the throttle on a spare channel . Cheers

I have tried mixing as this was my intent from the start. When that didint work I tried it driectly on another channel with no joy either. I havent tried to reverse the channel but will try that as well.

Okay, so I managed to get it to work. On the Hitec system you have to reverse the channel off which the glow driver is run (like The Pope said). I did notice that every time the glow driver is switched on, the telemetry system complains about the receiver voltage. This was just a bench test but I will run the glow driver from a 2s lipo with a BEC module and only use the receiver to provide the input signal, similar to how retract servos are run. This is very important because if not connected like this, the glow driver may cause a receiver brown out in flight, as has been noted by some people on the Hobbyking webpage.

If you use a good 1400-200 LIFE 2s pack you can use it for both receiver and glow.
Reversing with these glow drivers is required no matter what radio because the Chinese designers did not understand that we want glow assist on low throttle and off on high throttle.
HK also sells a servo reverser so if you had a Y off the throttle you can have one branch to throttle servo and the other to servo reverser and to onboard glow.
Servo reversers are cheap and work well.

Note I would caution against a 2s LIPO as the "glow" may be a bit hot!!(oops I see you say with a BEC)

These onboard glow only draw about .8 amps at 6.6V because they knock it down to 1.2 or so for the plug so I am surprised your battery would go low. Using a reasonable LIFE pack voltage drops from 6.6 to 6.4 typically.

Thanks 4*60
I just reversed the channel on the Tx and that solved the problem. The battery i am using for the receiver is a regular 1000mah NiMH and i think when the glow driver switches on, the battery doesn't have enough amps available resulting in a dip on voltage and subsequent brown out.
