Since this thread seemed to have been orphaned, I thought it might be useful to use it to compile a collection of pictures of other nose wheel leg designs. Whether or not these can be adapted to the RV-?A, people have been interested in what other aircraft designs have done. If anyone has any pictures, especially without the pants and cowling, please, share. I think the Grumman, Cirrus, and C-162 would be interesting.

How is the nose gear mounted on the various Pipers? They all seem to have a nearly vertical oleo strut from what I remember.

I'd love to see a picture of a 7A or 9A similar to the RV-10 in this thread, just to compare the pictures side-by-side.

I will try to locate a picture of side by side two seater RV-xA with modified nose gear mount. RV-10 style. Was so much work involved that Russians decided it's not worth.

RV-7A vs RV-10:

The Jabiru looks nice - ridged, light weight and not likely to stick a non-moving piece into the ground. But it would put the the wheel in an entirely different location. Then the RV-10 looks pretty good too. Am I correct in assuming it's made of tubing? Presumably the design is intended not to flex and would hopefully completely fold up on failure rather than snapping back and causing the airplane to pivot on it. From what I can see of it a new builder (me) would do well to utilize a design similar to the 10.

The -10 design looks so similar to the -7A design that it might be pretty easy to change. The pivot on the -10 sits below the lowest bolts though, and on the -7 there isn't any extra room there. So there are still challenges, but it doesn't look insurmountable.
