Yes I agree that 5600 rpm is a little to high. ASI indicated 60 knots on climb out - a little too slow and steep I think. The pilot said that he lowered the nose at around 1,000 ft but I think he should have dropped the revs after getting in the air adjusting to maybe 5,000 for the climb and climbed out at 70/75 knots. By the time he reached 1500 ft it had reached 265 F and didn't want to come back down on the downwind leg - 4000 rpm / 85 knots.
A courser prop would help to lower the revs and decrease the climb angle a bit - he was at 1000ft at the end of the Gladstone strip which is about 6000 ft long. Not sure how much courser a 3 bladed Warp Drive can go to and remain efficient - its through a 2.1:1 box and has 14.5 degrees at the tips now.
Ive got a universal sandwich adapter coming and will try and get it test flown again in the next couple of days.
