[NSRCA-discussion] WOW - Brio maiden

[Dean Pappas]

Hi Stu,
Yes,  it's easy now, but back in the eighties Nat and I were discussing this same experiment with a P8, as a fair number of P8s trimmed beautifully, while others had this canopy pull with right rudder and a belly push with left rudder. I've never seen a plane where it was the opposite, but with a reverse pitch prop, a left-thrust adjustment, and two swapped wires we may be able to tell once and for all.

Kelly,
What Dave wrote has worked more than once.
What I believe Don S wrote was that if you are carrying left aileron trim for level flight, then twist the wings to eliminate the aileron trim.
This may help or eliminate the slow left roll on power-off vertical dives. If you don't have that problem to begin with, then never mind.
The different pull-push with rudder may be affected, but before you try either approach, look carefully for wing-to-stab twist as viewed from the front of the plane.

Doesn't help your Phoenix 8 but how about a pusher prop on an electric?  You
can change direction on the electric motor and see how that affects the trim
problems.

Nat,
You're absolutely right! That's why you should pick up a copy of February's
Flyng Models.
I still wish we'de had a backwards crank for an OS FSR to test in a Phoenix
8 with the same issue.

Kelly
Contra rotating props would solve the knife edge trim needs. Congratulations

you have a straight airplane.  Nat
