When cruising, there is almost no need to make small adjustments to the pitch trim, it feels like the aircraft has built-in auto trim. I don't know if the real P-40F has a similar feature.

When controlling the pitch of the aircraft, it feels like the pitching process is not very natural, there is a feeling of stuttering or even getting stuck and then continuing the pitching motion, this was noticed in the preview video before the P-40F was released.

One of the purposes of introducing the longer tail variant of the P-40F vs the short tail P-40F was pitch stabilisation. This is a true to life effect of the aircraft. It's not an auto trim but a very stable aircraft when established. 

Thanks for the explanation, I really like the fine model and sound of this P-40F, I hope it will be the next WWII aircraft with excellent potential for MSFS.
