What torque pulses? Today was the first run
with the complete engine in flight configuration, meaning engine - psru - prop.
No vibration out of the ordinary. It, off curse, is shaking at 1300 RPM idle,
just as my Soob does. Once it goes over 1700 running like an electric motor,
almost.
Sounds great Richard. What prop are you
running?
A couple thoughts come to mind about why you might not have
the same torque reversal problems I have. One is the damper in the Hirth
gear box. It might just be that it's exactly right for the
job.
The other possibility I've mentioned before is that maybe
you're benefiting from one of the PP shortcomings. As I understand it, PP
engines tend to have less power down really low in RPM's.
Perhaps this lack of torque is what's keeping you from having the torque
reversal problems. I don't see a down side to this, and it would
be THE reason to go with PP for me (if indeed it has anything to do
with it).
Cheers,
Rusty
