I wish this thread was on the replica board instead of buried here on the pioneer board. There would be a lot more views and comments there.
Castoring nose wheel system. Need to be as simple as possible, yet sturdy enough to handle the less than perfect taxiways at some airports. Here are some random thoughts.
Why not start with a tailwheel off a Cub, Champ or such. Benefit of having both locking and castoring modes. Would make taxing in a straight line, or in a crosswind a little easier. Add a couple of clip on pushrods from the rudder pedals an you add steering capability.
Maybe weld up a modifed A frame with the castor at the apex. This would place the castor ahead of the nose wheel. The base legs would have some tubing welded on that is split lengthwise to fit over the forks of the nose wheel. Use the other half of the split tube as the clamp. Weld on a couple of ears on the upper and lower clamps for bolts and wingnuts to hold the assembly in place. Line the clamps with felt or leather to protect the paint on the forks. Just might work!
I flew several cross country flights in ultralights over the years. Never had a chase crew, but wished I did once. 2 biggest concerns were fuel availability ( 2 stroke oil/mogas mix ), and miday thermals. My Cub rides turbulence like a Mercedes car, compared to how my ultralight handled it!
I'll have to find a way to make a few of those shows. Sounds like way to much fun!
