I agree with the theory, but the practice proved otherwise.
As for the increased RPM turning circle, we did try it both ways and yes it
was less of a turn in the unfavourable direction, but not by all that much.
Interestingly enough, I have now had chance to try it on grass (very wet
grass though, so some skidding may have hampered us) and the turning circle
is just a bit less than the standard tailwheel, with our new setup. This was
down at Chavanenage with Martin Stoner where we are trying to convert to
type, but having real problems with the weather. Only 1 hour flyable in 3 days.
