I am a big fan of Fred Weick and his wonderful Ercoupe including its remarkably simple wing structure, but not everyone likes the twin tails or the lack of rudder pedals in a "true" Ercoupe.

Back in 1946 Aeronca tried to get in on the all-metal (with fabric-covered wings) light aircraft business by license-building the Ercoupe but quickly came to the same conclusion and so revised the design with a conventional tail, much more spacious cockpit, and rudder pedals. Of course, that was a horrible time to introduce a new light aircraft and the project died on the vine.

Still, looking back at the Chum today, it seems like a great foundation or at least inspiration for a modern light sport aircraft that would emphasize comfort, ease of access (for a low-wing design), docile handling, and the ability to operate from dirt or grass strips. A lighter modern incarnation ought to get the empty weight down to 750-800 lb leaving a useful load of 520-570 lb given the LSA maximum weight of 1320 lb for a landplane.

Essentially, you'd end up with an "off-road" version of the RV-12. Does anyone else like this idea?

I like it ! the classic looks are spot-on for the period. Definitely looks kinda roomy!

But the truth is that there's not much about it that is unique or (more or less) unavailable elsewhere however. I'm guessing the Zenith CH-601 HDS will do the off-road stuff better because of the big thick hi-camber wing. The little Aeron-Coupe is much prettier than the Zenith, and perhaps a tad faster.

Mooney M10 if it’s the configuration that you love. I don’t think it’s any tougher or better than a RV12 or any other this size like a Thorp 211, Zenith. None are made with it in mind.

A friend in an Ercoupe followed a buddy that was flying a C140 into a pasture. When they left, the C140 dumped a bunch of flaps and was out of there easy. My friend in his Ercoupe through the tall grass could not get the plane off the ground and wing into ground effect. Fence coming up he yanked it into the air and cleared the fence by inches. Maybe off road in the desert southwest. Rocks on the bottom of the wing not so good.

I know someone who just bought an Alon one and I almost bought a 46 D project in high school. First GA airplane ride. Cool planes. Grass runway would be about as off road as I would want with one.

To be clear, when I said an "off-road" version of the RV-12, it was with tongue in cheek. I simply meant that it would be good for relatively rustic dirt and grass strips, not for exploring sand bars with the souped-up super-STOL Cubs. That knee-action gear and big tires look like they would do well in that sort of environment.

I like the Aeronca 12, looks like a good airplane.
The knee action gear on the Ercoupe makes every pilot look good. Never liked the alon, added to much weight to make it look modern. Have owned 2 Ercoupes. Serial # 24** , don't remember for sure. Fabric wings, no rudder pedals and C-85. Serial #4854, metal wings, rudder pedals, C-85. The lighter early one was the best flying. Have flown 4 other Ercoupes.

Yep, I like it.
