Just wanted to clarify the useful load scenario with the Cleanex (C model) airplanes with the Corvair conversion. I have a useful load of slightly over 500 lbs. Of course that meant bumping the gross ~8% to 1250. Tested to that and it handles like an airplane at gross. If you went without the extras I have (paint, dual landing lights, etc) you might build a polished legacy model C (Cleanex) at an empty weight of ~700 lbs. Set the gross at 1200 and you still have a 500 lbs useful load.
I typically carry myself, full fuel, a bit of baggage, and a passenger (sometimes the wife) and I'm still under gross. Many of the Jabiru 3300 models are set to a gross of 1250 lbs and others can confirm the airplane has no bad habits at that weight as long as the CG & weight & balance are correct. Being a little guy or having a little wife is a wonderful thing. I'm only a doughnut or two away from 200 lbs most days. If my passenger weighs more than I do then it starts to get a bit crowded in there anyway.
I believe that Mike January & I are the only ones on the list that have flown both the Aerovee and Corvair conversions on this air frame. I really do get a LOT of off line inquires concerning the Cleanex and Corvair engines in general. I personally think it's a mistake for any company not to endorse and make a path forward for any engine that can reasonably be used. Zenith does that with their product. They will assist in any way they can to help the customer put whatever FWF package on the airplane that will work (within reason of course). While Dan Weseman designed many parts for the Corvair and built his prototype Panther with a Corvair engine, he was wise enough to offer mounts and cowlings for a variety of engines that he perceived his customers would be using. The fact that he used the Corvair to launch a brand new airplane concept should not be minimized. Dan is an incredibility intelligent individual and isn't known for taking foolish chances. What he did speaks volumes about this engine.
All this being said ... I'm not anti-VW engines at all. I'm just of the persuasion that what it's being asked to do on this air frame is slightly beyond what can reasonably be asked of it and keep it within the realm of high reliability. It does work on a very light tail dragger but will require dilligence on the maintenance (heads & valves especially).
Just one man's experienced opinion. YMMV but I doubt it!
