There is a Playmate in the EAA museum, but AFAIK, not on display except that it is rolled out of storage during AirVenture. This one has an O-290. A Spotter’s Guide to the EAA Aviation Museum Aircraft Around the Grounds scroll down.There was a guy near show center at OSH 20+ years ago in a Stits Playmate (I think; 2 seat version). Whenever anyone stopped by to talk, he'd fold a wing and then unfold it.
I think FPV quads are the way to go. I always hated having to think about control inputs as the aircraft makes it's circuit of the field. Video in goggles just lets you fly by ground reference, the way it's meant to be. Plus, indoor racing through an obstacle course is a blast that can't be replicated, even with the pylon courses they have now.He was unsucessfully trying to build airplanes for the last 15 years, and never flew any of them :-/ He bought us both quads at the same time after I got stoked on them, and now he flies almost every day too. I like to think, he's tickled pink now, but wait until we upgrade to something more cutting edge, immersive, punchy, aerobatic, and banging...
Why couldn't it be just a manual fold system? An EAB wing weighs a lot less, and we don't need a complex synchronized scheme for the wing movement. Add in the idea that the wing only needs to fold up to be less than the span that's street legal, and the hinge can move outboard on the wing, which reduces the weight of the folded panel, and the forces acting on it.to do something similar in an E-AB, would be complex to build, heavy, would requires hydraulic (or electric) power, and would complicate the fuel system.
For VFR navigation, with capability I don't use for weather/ADSB in, and virtual instruments, I use an Ifly GPS 740B. I also use the ifly app on my Android phone and Ipad, which gives me a neat split screen with EFIS/moving map onscreen with synthetic vision (including labels for nearby airports that you can click on for plates and direct to nav. Super useful). The Ifly hardware isn't very expensive, and the app is cheaper than the more well known software out there.Once you add much more that that, however, and especially if you want any kind of electronic navigation tools (still just VFR), then the price points start to merge and then electronics come out cheaper. MGL and GRT in particular have packages that challenge traditional instrumentation on price if you want any kind of moving map.
Why hasn't the old Grumman folding system where you fold the wings along the fuselage, caught on?
It didn't seem as if you has to disconnect the aileron controls. Is that because they were cables?
Complicated to build?
My comment was in reference to “the old Grumman system”.Why couldn't it be just a manual fold system?
