Graham - if you just give the max speed information it is not very impressive.
4kts better at 135 kts is an improvement in efficiency of around 9%.
But at 4000 rpm you were doing 115/118 kts which is much more impressive.

PS Due to the strong pound (weak FF) the PV50 electric In Flight Variable
Propeller is the cheapest its ever been.
