onboard glow driver
I go the easy route on this.
If I run onboard glow, I just use 2 4500MaH D cells and hook the neg to ground and the pos to the plug. When I am ready to fly i connect the glow plug, when I land, I unhook it. No electronics to foul up and nothing to set or maintain except the batteries. The 2 cells will light a glow plug for about 4 hours, so you get a days worth of flying out of 1 charge.
