Hi Ernest 

Look for Deon information first . I my opinion engine 1150 is wallet proof , but You can find some problems with this setup 

1. Is a cooling problems engine need well done cowling 

2. Gear box - in my setup i have to change every 200 hour bearings after 400 Hours i chanage a tooth weels in gear ..

I check two gears ratio 1:3 and 1:2,75 better is 1:2,75 with my PESZKE prop . flying like R912 80hp My engine is model 1150 R 85hp  duble ignition max torque at 5200 RPM max hp at 6800 rpm  Take off RPM 6400 Criuse RPM 5600 - 5800 

Now i am using BMW in Stoll in this moment 640 hours in flight book and no problems with engine but some with reduction unit . 

Some more information
