Never thought of it, but by golly, that's a good idea!

I just bought a Sullivan Dynatron a few months back, but had I thought of it, I would've tried it with one of my deWalt 18V drivers. Those suckers have torque up the wazoo. They drive 3-1/2" drywall screws easily into SYP without a pilot hole. I'm sure even my old 12V gun have enough juice to start a 1.20.

But the reality is that unless you already own a drill driver and then just do the conversion, buying a good size gun with enough cahones is going to cost more than a heavy duty RC starter.

Another problem is that most HD drill drivers are pistol grip. Because your trigger hand is offset from the rotating axis, you'll have to hold it two-handed to start the engine. This means you'll have to have someone else hold your plane.
