This is sort of funny, I have been flying gas for years (14) and have never owned or wanted to own a magneto ignition engine. They are great for lawn & garden equipment. I think they will have an important role in sUAV's. In my hangar though if it is heavy, I don't want it. Magneto's are heavy.

I think going home without injury should be the number one factor in all we do!

Although for electronic ignitions the power gains from a timing advance are minimal, the ability to hand start easily is very practical.

When ever someone at the field is having a starting issue, air, fuel, or spark are missing. When they come together the engine runs (that is all engines that are mechanically sound)

That has been my experience.

As for large electric starters, when someone asks me to hold an airplane while they try to push with 50-60 lbs of force on a 35% airplane because they are afraid to hand start or have a bad shoulder or lack arm strength. I have to refuse for safety concerns. Even if they point out that I will not be hurt, I can't participate in something that just seems unsafe to me.

20 inch APC, I flip with a 1/2 inch heater hose with a wooden dowel through halve of it (home made chicken stick). Larger or wooden I hand flip wearing a glove.

I will use an eighteen volt hi-torque on my Zenoah 20cc ei sometimes in the winter because I can hold the landing gear and push against the prop by myself safely (the carb is dry the first start of the day and this is quick and easy).

When all this fails, it is time to fly electric.

I'm not sorry about the redundant safety line, no mater how hard it makes my post to read.
