Not the best picture.... but here's the trim tb I have on my IV Classic. Works great! I have a small lever inside the cab to set it for different conditions. For the most part I leave it as is and my plane flies stright and level with no stick pressure. I don't change it for take off and landings... I just deal with the stick pressure.

Oh yeah.... total cost $0. I just used the scraps of aluminum I already have.
