The plane rolls to the right as speed is reduced.

that makes sense wells, because if aileron trim is to the right to compensate for torque to the left, as you decrease the throttle and torque decreases your aileron trim will be overcompensating, and you will have to decrease it. The same thing happens in brand w.

oh wait, I totally misconstrued what you said. If it rolls to the right without reducing the throttle then something is wrong.

yeah, without reducing throttle...do a hammerhead. You will have to use left aileron to prevent the roll...maybe it's just my version got porked during install or something?

It's not your version Wells but it's not torque. The effect you are seeing is caused by the slipstream hitting part of the wing and causing a different change in the AOA to each wing. The slipstream hits the right wing with a downward direction reducing AOA and with an upward direction on the left wing increasing AOA. It's way overmodeled right now and is having a lot more than a subtle effect. This and other modeling issues will be addressed soon.

Ok Pyro,

I tried the P-51 and was seeing some really strange stuff..like <200 mph it was rolling right, between 200-300 it was rolling left and then above 300 it rolled right again! I know the fin offset would cause the right yaw/roll at high speed, but I couldn't make sense of the low speed stuff...thx for the reply!
