Garmin G3X in a new RV-12 (Experimental) . Doing Phase 1 tested Autopilot. Heading works fine. Did V/S to climb 500 ft and it captured. Then 30 seconds later it started to dive. Disconnect autopilot the trim was nose down, significantly. Any ideas. This was first and only use, Knocked off using it until I can figure out what is going on. LESSON never use autopilot close to ground.
