Dear Carenado-please fix (xplane)

I consider your f33 one of the best planes ever made for xplane. However it has two what I believe to be bugs.I have tested other aircraft and have not seen these traits.Bug 1-the plane needs continual left rudder in level flightBug 2- You trim the plane for level flight-it stays for a while-starts climbing-you do the same-it stays for a while-and then starts climbing-and finally you run out of trim-and the plane climbs requiring continual yoke downforce.I am eagerly looking forward to your new vtail release-mostly because the inside cockpit resembles what I flew for 11 years.Keep up the good work and look forward to many more releases for xplane!
