Throttle mixing for on-board glo driver

[KoalaDave]

Hi All

I am trying to mix an on-board glow driver into a Channel 7 on my RX, rather than connecting it with a 'Y' lead to the Throttle channel (1).

I have set up a curve that take the output for Channel 7 from 100% at position 0 to 0% at position 3 of a 5 position curve. I have switch SF set up as a throttle override / kill switch

What I am trying to achieve is that when SF is in the override position the Throttle servo is disabled in the fully closed position and the glow driver it disabled by taking it to what it thinks in 100% throttle. With SF in the active position I have normal travel on the throttle and the glow driver starts at full power and is taken to the 'off' position as the throttle passes 50%

I have attached the eepe file so you might be able to figure out what I am talking about and where I am going wrong

Thanks in advance
