Narrative:
During takeoff, electric trim stuck in up drive, cancel switch inoperative, and immediate landing with gear up. Vigilance of tower prevented wheels up landing when I missed our landing checks on immediate landing. I would like to point out that the vigilance of your tower at boise prevented a serious accident. I was landing fast to prevent a stall when flying with full nose up trim, because of the all-flying-tail of the piper archer. It required all my strength forward on the control column to overcome the trim problem. I flew 360 degrees from takeoff after this error happened. I was careless enough not to have done my pre landing checks. The tower to whom I had declared an emergency saw my gear up. I lowered gear around 200 ft and completed an uneventful landing.
