Another vote for the Osprey IIIn the good old days before so many kitplanes there were several. The Pereira Osprey II, the Volmer VJ-22 (I think that's right), the Anderson Kingfisher, the Spencer AirCar, the Taylor Coot, and probably more. They used to show up regularly at fly-ins. Googling them will no doubt turn up sellers of plans, and if not, maybe someone here has a stash of them in their basement somewhere.
I met John Jeffries, the other guy who was involved with the original Enterprise model. He had rebuilt a truly show quality Aeronca Chief and a matching Ercoupe here at my home airport. Survived getting his head darn near chopped off hand-propping a Cessna Cardinal. At one time I think I had heard Volmer was based here at Whiteman Airport (the photos of him standing in the VJ-23 glider were taken in the hills behind the airport), maybe some of the model was built here too? As Spock might say... one can only theorize...Wow, that's quite an Enterprise.
That’s pretty well a reality of any amphibian. Look at it the other way: observing gear up or gear down is an easy procedural thing you do once before landing, you recognize the dangers of getting it wrong so use that respect for the consequences to drive you to never land without knowing the position of the wheels. Not guessing the position, or trying to remember it, or making an assumption, but knowing where those wheels are before you touch down, all the while being prepared to fly an overshoot if you don’t like the answer.If you accindently left the wheels down in an amphibian(like the volmer..etc) ...does it have the same potential to flip like a float plane?
Yup. But the temptation most builders face, and many succumb to, is to add an electric motor or hydraulics to do the grunt work. That adds weight, cost, failure points and the need for an emergency gear extension system.Not for the first time, I'll say that what we really need is an original design homebuilt amphibian inspired by the Shavrov Sh-2 complete with the simple hand-cranked, cable-operated landing gear.
