Yeah, I was thinking that. But, if he could get reasonable performance off a 4-cylinder like an IO-360 it might be preferred. Or we just ask Patey to throw as more money and horsepower as possible and now you have a toy for a limited few. RV10 is nice, but again, I don't like the nose gear and the composite top half is not as appealing as the traditional RV construction... to me, anyways. I think the Murphy line or the S21 meet my thinking the best.pipercrusin, Van already has your design; the RV10. Unfortunately, it'll get off quicker and cruise a lot faster than your wish list. ;-)
I suspect that an all-aluminum Bearhawk (pick any model) from Van's would just about suck the life out of Bearhawk sales, except for the hard-core 'working' guys that needs to be able to field-repair the fuselage with a sledge and duct tape. Probably 90% of all of the 'STOL' designs being sold rarely see grass and likely never see dirt/gravel anyway; just like all the 4wd Jeeps, pickups, etc running around on the highways.
