I'm in the process of welding in the axles on my super ace, and am wondering about the toe in/out alignment. I've think that I have decided on a toe out, but how many degrees from datum should the axles be toed?OCB________________________________________________________________________________

Bob: As nobody has yet responded to this post let me give my two centsworth. In an article by Marvin Hoppelworth in an old edition of SportAviation discussing this matter Marvin recommends 1-2 degrees toe out.The theory (and it holds true in application) is that when you turn tothe right on the ground the ground pressure on the left wheelincreases. If this wheel is toed in it will be pointing slightly inthe direction of the turn (to the right). This wheel now has moretraction and thus more directional influence and will tend to pointyou tighter into your turn. The result is what is called oversteer inthe automotive world, and makes something difficult to control. If onthe other hand the wheel is toed out it will tend to pull you backtoward straight which results in a positive stability. This applies only to tail draggers. On nose draggers thesituation is reversed just as steering in a vehicle with rear steeringis reversed.... I hope this helps understand the matter. I personally would usevery little toe out... just enough to be sure that toe in did not-----Original Message-----
