There is no universally accepted answer to this; many different opinions. Do a search on this forum for Wheel Alignment and you will get some good discussion. Since the Grove gear has the axle mounting pads machined after the gear is bent to shape, it is quite accurate at neutral toe-in/out. Many guys, including me, just stay with that and have good results (Kitfox SS7).

Thank you for the advice, I'll try it neutral and see how it goes for me.

I checked the toe in on my Model 5 and found it was perfectly neutral. I like the way it handles, wheel landings feel good.

Thanks Phil I appreciate it!

Toe in is used for tracking on vehicles that steer from the front. I.e. Four wheel autos and some motorcycle trikes. If you have a tail dragger you want either neutral or toe out. If the aircraft starts to turn, weight shifts to the outside tire toed out (away from the turn) and tends to track straight. If you have toe in the tendency to turn would be increased.

If you have a nose wheel, there is no other front tire and thus it has no toe in. When the aircraft starts to turn, weight shifts to the outside main tire which is already aft of the nose wheel and aft of the cg. Thus a nose wheel aircraft has a natural tendency to track straight and does not require toe in or out.

When setting toe in or out remember it doesn't take much. Just 1 degree would track 1 foot off for every 60 feet traveled. That's a lot of scuffing. Typical toe out is about zero to 0.25 degrees.
