Wow!  Bunch of answers in few hours.  We all have those nuggets of wisdom, don't we? ;)

My two pennies:

In real life flight, I found that even when I assumed I was climbing and maintaining a correct heading, etc, I was still drifting left of the runway because of P-torque.  It's an irritant, to be sure, but very correctable.  What I tended to do was adjust my heading by about 3 degrees to starboard as I took off (your twist, my rudder pedals), and slowly let that out as I get up to pattern alt.

Travis: I've noticed that drift, and an almost gyroscopic effect while flying and trying to maintain a steady course, until now, I thought it was the wind pushing me around, (lots of bad weather in the world here lately)

This particular aircraft might need looking at.



Here is the link to the plane, paints, & paint kit. :)

Sorry, I meant the aircraft that Travis flies in real life. If it's trimmed properly it shouldn't have this problem.

In my experience a properly trimmed rudder will pull left with throttle open and pull right with throttle closed

In an aircraft with a fixed rudder trim tab, the goal is to usually have a trimmed aircraft at cruise speed. 

As for locking tailwheels, the P-51 and the T-6 to the best of my knowledge do have locking tailwheels whenever the stick is pulled back, and is released when the stick is pushed forward.

Fact is all aircraft of a similar gear geometry exhibit these same torque/P factor characteristics on takeoff.

I could be wrong but don't think most single-engined WWII fighters had this feature. Certainly not the Bf 109 & Spitfire.


Must admit, Hagar, I was thinking of FS models rather than the real thing -and all high-performance aircraft rather than just the 109........

Not sure about using brakes on a typical WWII fighter during take-off or landing. That would usually end in disaster.


As a matter of fact they did - risking possible disasters seems sometimes to have been the only way to avoid certain ones.
