Just look at how many people are flying 24-25% SA on glow power. Look at all the airplanes that are readily available for cheap money in this class. Big glow engines are cheap too. The numbers are probably ten times the 33-42% on big gas.

I think it would really take off if properly advertised. Set the limit at 74" and no limitation on weight or power. I think this could effectively limit the aircraft cost to $1000 or less. Sure guys will build flying bricks with 50cc gassers. It won't be a competitive advantage though.

I believe it could eliminate or reduce the intimidation factor and change the image of IMAC as a rich man or second mortgage sport. Sure, I can fly my electric 32" GWS Extra and beat a gigantic Aeroworks (with enough practice), but who would really be interested in trying. Not me.

Like I've said before, people are most interested in participating if they are doing so with their peers. That means similar airplanes, budgets, and personal investment in the hobby.
