I just got the THRUSTMASTER T.16000. I am flying BoS and the Yak-1 noticed that the plane wants to pull to one side and down a bit. I am hoping that when the web sight is properly working that I can download T.A.R.G.E.T and use it that will correct that. It is replacing a MS FFB2 Sidewinder that works fine on one PC but not on my new PC. Point being that the Sidewinder has no issue like this. Regardless, I don't know if this is a fault or not.

Well if your device is calibrated in windows properly, I would say it is more of the behavior of the particular plane you are flying.

While I have not flown BOS in some time, I do see similar in TF Cliffs, more so in the Hurricane. And of course different speeds require different levels of trimming.

Some of these planes do not have certain trimming available, I get around that by indeed using a TARGET script, I can trim both my y and x axis on my Warthog stick, I have mine programmed to the HAT 1, using the paddle as a modifier.
