I have designed my own "soft start technology" glow driver which works an absolute treat for DZ engines. I would say it is almost a must and you can go flying on your own.

You can use it as a conventional glow driver by using the ON/OFF switch or you can simply press the RED button which turns the driver OFF from anywhere between 1-10 seconds by adjusting a pot. It uses switching regulator technology which is more efficient and can deliver up to 5 amps which will burn of excess fuel in any flooded engine.

The analogue meter is also a must because it tells you exactly how wet the glow plug is. For example when I prime the engine I expect the meter to sit at 4-5 amps until the fuel has burnt off and then it should settle at just over 3 amps when he plug is dry. I know if it isnt drawing 4-5 amps after a prime then I know that no fuel has got to the engine.


I have built a number of these for friends and they are most impressed. I have no plans to manufature but I could be tempted if there is enough interest.
