RE: Ziroli P-38
Chris:
The best advice I or anyone else can give you about single engine operation on a scale P-38, is don't.
The only insurance policy anyone will write on the plane is your check for two rate gyros, as strongly and repeatedly recommended by Twinman. One on the rudders, and one on the ailerons.
With the engines running adjust the sensitivity until the surface starts to jitter, then back it off a little. At this setting the gyros will fight you in flight, but in the direction of more stability. You can back them off a little at a time until you have the control authority you want, but remember less sensitivity also means less assistance when/if an engine quits. And they wont save the plane, they will just give you more time to save it.
And the first step, regardless of altitude, is cut the throttle. Then nose down to maintain or regain airspeed, and get the plane right side up again if it went inverted.
But still the best advice about single engine flying on the P-38 is don't do it.
Bill.
