And in (training) microlight aircraft it's not unheard that the 912 will go

u have on the box now, and have you had a 600hr service, and if yes, what w

with an Arplast PV-50 prop in fine pitch it=99s set to give just und

set to cruise I aim for 130 Kts but I have to keep coming back on the thro

he problem started after a prop service, normally I tend to cruise at 125/1
30 for 4650/4700 rpm-ish, there=99s 10=C2=B0 difference between fine
and coarse pitch, which way should I adjust + or =93 the 10=C2=B0 pro
p difference?
