September is not likely for me with the kids school schedule, will look at anyway.
Phil,
Likely your problem is that you need to fly the rudder more.
Until that head has some stiffness it just won't have a lot of
control. Mine with cyclic pusher or tractor don't seem to have
the problem that the wallis does. But they both have
fairly rigid heads with lots of control.
Did you ever get your TREX parts?
