I've been running one for a couple of years, it's a good engine but there are better engines out there, if you want to run 60% you need to machine the top lip of the sleeve down to get the correct squish band clearance. I run my on 30% with a Salisbury carbon pipe on a x440/3 in a mono, not the fastest but works well.

We have this engines in FSR-V (endurance boats). Run on 25-30% nitro and 16%(castor/motul 2T - 50/50). Broke a conrod in one of three. As Yukkers Vitaly says "Japanish catastrophe". As Steven says not the fastest. On my opinion Novarossi is best choice in this money.
