Re: [Titanaircraft] Re: tail wheel

I think it would be a challenge to design something that would
effectively and repeatedly absorb energy directed perpendicular to the
tailboom without being heavier, larger and more costly than the existing
design.

The only thing I can think of that would not be larger would be a spring
steel skid. You'd have to reinforce the boom at the skid attach point
and you'd lose the ability to roll the plane around on the hangar floor
easily. It would be heavier.

Not saying it can't be done, but I'd probably direct my energies towards
something else that "needs fixing." If you've already built the
tailwheel as designed, I'm not sure why you'd bother changing it.
