Light sport aircraft are limited to ground ajustable propeller but....... If there was a 2 speed transmission with a governor to keep prop speed around 2700 rpm
In low gear with a ground adjustable prop over piched you could run up to Max rpmand have power to spare
Once up to air speed your automatic transmission would shift to high gear letting you back off on the throttle or cruise at 139 miles an hour
Transmission like this could be built to be about 25-30 lbs and remove your gear box that is from 21- to 40 lbs just a thought
