REFLECTOR: Main gear toe-in

Whoops - I hit the send button too quickly - here's the Aviation Consumer article:

  I used a pocket laser pointing along side the outer edges of the tire, projecting onto a card board box on the floor abeam of the nose gear.  By the way, I left my Velocity on the ground but did pull it forward so that the gear would be in the same condition as when rolling out on landing.  After doing all of this, I still had some quicker wear on the outer edge of the left tire - right tire was pretty much even. So I added a shim to the left tire to point it outwards.  I feel the ultimate measurement is tire wear - i.e.. get it as close to the 1" toe in as you can, then monitor tread wear (I used the depth gauge of my dial caliper) and measured depth on the edges and middle at three places then compare readings over 25 or 50 hours.

  By the way, considering new tires - our Condors are not the best tire for tread wear.  Aviation Consumer tested a number of tires and the best tread wear per cost is the Goodyear Flight Custom - twice as good as the Condor.  And the extra tread depth of the Goodyear does not equate to a larger diameter tire - it is the same as the Condor.

    Laser and welding are great ideas. Thanks

    Landing toe was ok to start with but was two inches out with wt on gear.

    By what Velocity told me and what we did on my XL FG at the factory was to set toe in and camber with no weight on the wheels. It has not resulted in unusual tire wear. I do not pretend to know about SERG, but ask Scott B. about it. I think he will confirm my approach. 



    The laser , which was my adaptation as I wanted to avoid tire removal etc., cost about $25 or so -----money well spent and a whole lot easier than removing tires over and over. Have to trust that the axle stubbs are square on the end as you have a base of only 2" to use instead of the whole tire/wheel combination.
