Mines a 406 pretty mild hydraulic roller idles like a kitten

It can spin faster but it signs off at just under 6.
(In my experience accessories dont like to spin much faster than that anyway.)

Makes 500HP and about 515Ft lb.
Ive spun a 4 blade 26 61-6200
It'll shoot this little tunnel across a lake or river at just a hair over 90 and handles like slot car-

I have to ask

Is everyone running alpha drives?

Im running TRS drives and only turn up to about 4500 at WOT. I thought it should be higher more like around 5000. Looks like some prop work is in the future.
