Glow plug driver advice please

[Paul Williams]

Hi I just bought a glow plug driver that can be switched either manual on-off or using a separate channel on tx. I am concerned that should I forget its on it will drain rx battery and you know the rest.

it draws it power through the rx. Can I change this but still use the rx to switch it on-off? If I take the red pin out of the plug and wire it to a positive on a separate battery, then take a negative and wire that to engine and separate battery will that work?

Try this, I've used it successfully. **LINK**

Try and look at the SM20 Glo switch. See what you think.

The Fast Lad one looks identical to the HobbyKing one that is even cheaper. I bought two of these and have fitted one to the model I'm building. Works fine on the bench, not used in anger yet, however these are both just for engine starting, not for in-flight use.

I have a couple of the HobbyKing ones in use (on 50 sized glow Helis). They work well using a single flight/glow battery, but then I'm using a 3700mAh 4 cell "C" sized pack (which are my std pack size for std digital equipped Helis.

Yours should work OK wired as you say like a UBEC/Opto ESC paired system of connection, but it's easy enough to test.
