I love my Supertigres, I even have one of the made in China Supertigres and it runs, well, SUPER! I never owned a Rossi but was always impressed by their performance. I am very tempted by the Nova rossi line and I would really liked to add one to my stable.But the other OEMs had piped and high nitro engines that would out last any OS in the same environment.
I was showing that OS had chosen poor machining practices in the making of the engine.
I happy you were satisfied with the product you received from OS.
I think objectively if you were to put the engine from OS on a dyno or even in an engine dominated contest you would have found that just about any of the Italian Stallions I mentioned would out perform the OS in both power and durability.
My beaf with OS and Great planes was in the marketing and warranty of the product. I never expected an OS engine to be a fire breather (well not after I learned what was what in P&L design).
I loved my OS Surpass 70 as a fine sport engine.
OS/Great Planes had a very effective marking strategy. My hat is off to them for having the sales they did. Unfortunately I think it was as a result of dissipative, if not down right dishonest, marketing.
