"Nobody (apart from the AAIB) has commented on the 20 deg pitch up on climb out."
I have an aircraft in the same class (VLA). With a VP prop a CSC-1 + 100hp 20deg would be about normal. The ROC would be quite impressive with everything working. My aircraft would do 1400fpm with a fixed pitch but when I upgraded to a VP + CSC-1 I got around 1750! Yes my mod was cleared by the LAA
