Is this not an effect of P-Factor?
Hi Ryan,
Spiral airflow has much more effect to our flying, when it comes to line tension issues.
There is more P-factor in level flight due to out-thrust and flying yawed outward than there is during all but hard corners, with a flapped ship.
That's because flapped ships fly the rounds with the wing centerline
almost tangential to the loop.
On the other hand, that constant out/right-thrust induced p-factor is trying to bend our motor shafts into a bow, all the time.
The bow is canopy-ward or wheels-ward depending upon the rotation.
Take a metal rod, bow it and make it rotate, and eventually it or the bearings supporting it will fail.
Anybody out there remember the old Pontiac Tempest with Rope-Drive?
take care,
