So, don't be afraid of smaller size motors. Fo r heavens sake, don't use an auto starter type motor; way too powerful.

Works excellent. On Sat, Apr 11, 2020 at 12:42 PM wrote: > > > Hello all > > > I=99m looking at building a 12v battery operated aircraft tug, not a ride > on just a walk with.

Nuckolls, III" Subject: Re: AeroElectric-List: Re: Revmaster R2300 Ignition I've been pondering this topic for a few days. The ignition system on this engine is really rather clever . . . manipulation of 4 switches in pattern gives you a 100% check on condition of ignition components! I think I'd try to avoid adding to the complexity of this already 'optimized' switching philosophy. If it were my airplane, I'd craft a shield and gang bar (magenta and blue) to give me single-stroke shutdown of all switches. Mounting the switches on 0.8" centers makes for a compact cluster that goes to choreographing the toggle-switch-tap- dance during preflight run up.

Thanks for all the feedback and above all, thanks for serious consideration of my excursion into unnecessary complexity. I think it's safe to say I've been "talked back from the ledge" and will be installing 4 switches.
