On my 12 for one flight I was way over pitched at 3000' on a 50 degree day with 1/2 fuel and a 170# pilot and could hold 128+ knots TAS at about 6.5 gph. Climb performance was anemic and almost impossible to maintain above 5200 rpm in climb out. Reduced pitch some and flew awhile with 124 knot cruise but found climb performance to suffer too much with hot weather and when at full gross. Tried a few more settings ending back at Van's recommendations for all around use.
