Thanks, Larry this will work for me. I was going to set mine at 3/16 toe in
but will go with dead ahead. In the piper gear we try for 1/4 or better per
wheel toe in but that's piper gear. Cessna's we try for a little less but
still toe in. The 20 and 20/22 pipers are a little squirlie so we seem to
have better luck with a little more. Of course you have to do a gear spring
or bend to accomplish this as usually its caused from a ground loop or near
so and precision is a little hard to achieve. Again, thank,

That is true and I was using that to make a point.  The Diehl gear, 
in my opinion, has very little fore / aft movement, or at least not 
enough to be a factor.  I think that Mark Langford's and my slightly 
longer than standard, slightly reinforced, Diehl gear with over 1000 
hours of combined flight time would indicate that zero toe-in / 
toe-out works well.

While I don't question your statement "(Just apply your brakes and 
apply power and see how much they flex, mine move back about 6mm)." , 
that is not a condition your gear sees on most hard surface takeoffs 
and landings.  Rough sod could cause fore and aft movement but the 
effect on directional control has less effect with less tire to 
surface friction.  Any roughness causing the gear to flex aft will 
probably  call for immediate and aggressive rudder input to maintain 
directional control anyway, independent of gear alignment.

I think this subject is being over analyzed.  Go with what has been 
flight proven and move along.  Zero toe-in / toe-out on the Diehl 
gear works well and, if I were doing it again, is the setup I would use.
