Hi! Raimo
First off ....how is that little girl?
I hope now home and happy?
If my memory serves me right I think the block was 0.0025=9D
clear of the slip ring, but with any slack in the propeller assembly
must be pushed back for worst case scenario.
Trailing , leading or straight provides differing brush loads ....
Leading being the heaviest and hence more wear more quickly.

Dear Bob,
do you remember how much the MT brushes protrude out of the box ie. what
is the lenght of the unsupported brush part = the cap between slip
rings and a brush box brush side ?
I my case (just what happen to be in my Rotax & Airmaster combination)
this measure is about 1 mm or even less. I think then it is no matter if
brushes are a bit =9Ctrailing=9D,
=9Cstraight=9D or even =9Cleading=9D.
They will anyway soon worn out to totall slip ring contact.
Cheers, Raimo

Hi! Svein ,
I would still prefer to measure the actual angles and especially prove
them to be =9Ctrailing =9C

Hi Bob,
Appreciate your comments regarding correct installation of the brushes
relative to the rings.
My Airmaster was delivered with a brush bracket for Rotax 912ULS. The
holes matched exactly the holes on the left side of the gearbox, and the
distance to the slip rings looks right (small unsupported length of the
brushes sticking out, yet clearance to avoid the bracket touching the
rings).
Regards
Svein
