RE: Is toe-in good to have on a Ziroli Stuka used on asphalt ?
Ed, toe in is always good. On my Zerioli Corsair I had 5 degrees of play in the wheels (that’s each). So I set the toe in at 6 degrees to always give me a toe in. while it will make the plane more manageable I don’t think it is your problem. I think you may be the victim of rudder and tail wheel out of sink. I normally fly off grass but would go to contests on pavement. First noticed this on a P-47, when it would transition from tale down to flying of visa versa it would veer hard enough that I would over correct, ugly. The solution is next time out turn the radio on push the plane down the runway then move the tail wheel so that it tracks straight by adjusting the rudder to tail wheel linkage. That should calm it down along with toe-in.
