What one person does isn't really indicative of the rest of the sport though. If the gas engines become feasible you open up the market a bit.

ZDZ-40 RE starts to look interesting as does possible new engines from a couple well respected manufacturers. Overall initial cost would be a bit less than a YS 1.40 DZ, with a lot more power, and a $2/gallon fuel cost, saving you a lot of money over the season in fuel alone. Then there is the ease of use. Set the carb and basically forget it.

The increased power available offers up some very interesting design possibilities too all staying within the 2m box. Especially if we get a slight weight increase to play with.
