GAS Stearman Model 75 and Super IB75A Updated 13 May

[Daube]

Yes, a bit strange that it prevented the startup, but indeed after reading the manual and performing that pre-flight check, I could start the plane normally and do my first full test flight... with a catastrophic landing due to my poor rudder setup (twist axis of the joystick, with too much sensitivity...)
I'm still puzzled about the turns on ground. The aircraft is very reluctant to turn at very low speed... I still haven't fully read the manual but I haven't seen anything in the checklists regarding the tailwheel, excepted the tailwheel lock of course.

To be able to turn in the smallest possible radius, it is necessary to use the differential brakes by small pulses and the throttle in order to turn very short
Tailwheel lock is only used when on the runway for take-off so that the rear gear remains well centered so that the aircraft can roll in the middle of the runway.

the airplane can be taxied well enough using full rudder deflection, full differential braking (the * and - keys on the numpad by default unless you've mapped them) and careful use of the throttle to maintain momentum. Without much prevailing wind, which wreaks havoc on any taildragger,
you'll be able to swing the tail around to a workable degree. In my video previous page at around the 28:30 mark I have to swing the plane around at the end of the runway to taxi to parking and then again to park and shut down. You can see that it takes all you can do to get the results you want - but
it can be done. Is this accurate? I've never taxied a Stearman in real life so I don't know. Is it as easy as other models in flight sim where the airplane goes exactly where you want it to with a simple touch of the wheel brake or the least little rudder deflection? no - it isn't.
As to the landings - I was all over the runway and scraping the wings to death every time in the Super. Then I tried just doing main wheel landings and letting the tail settle until I could manage the rollout better, Then I did 3 pointers with the tailwheel locked for a while - finally I can manage 3pointers without dragging one or both wingtips or kicking the dog - (I don't kick my dog - figure of speech)
