Trim too sensitive?

[Baz000]

I'm not sure but it seems the trim hat on the SU-27 I can't get it to be stable in level flight using the trim hat on the thrustmaster warthog, I have to constantly trim even tho I am maintaining the same airspeed.

 

Anyone else experience this or can offer some insight? I have no problems with other aircraft like the SU-25.

I can usually dial it in fairly well. I think the bump "up" is less than the bump "down". So I go past the right setting by a bit going down and, then, come up to roughly the right place. After that I adjust the throttle a bit in whatever direction is required.

 

But, yes, the aircraft is pretty sensitive to speed changes. It doesn't take much to move it (less than the 10° increments used on the HUD). That being said, I normally don't worry about holding the exact altitude. As long as you're close to the right trim the aircraft enters a phugoid oscillation that keeps you close to the altitude you wanted. So, if you're a bit too fast for the trim setting, you'll slowly climb and slow down as you do so until you reach the tipping point and reverse direction and pick up some speed going downhill. At some point you pick up too much speed for the trim setting and start slowly climbing again.

Usually I do the opposite, get the speed right, then let the nose go down slowly and hold it with trim to the horizon. Autopilot really helps in those long flights.

It's always good to have options. :)
