Having owned the .61 and the .91 I feel safe in saying you'll love one, 0 or 5% fuel is the rule of the day and smooth is the way they run. Its sort of a long stroke engine so bigger than normal props work well.

If you give the engine a 12% nitro it doesn't work well?

Thanks

Joe,

MVVS normally is designed for low percentages of nitro.
I mix 2,5 or 5 % and the engine is happy with that, that's the 10 CCM, .60.
It is good to check the engine description for fuel nitro content.

Thanks Gary, I sure wish that I did but I sold the MVVS .61 and my MOKI .61 LS to the same guy about 3 years ago. They were both 23 mm x 24 mm bore and stroke. The Fox .60 has virtually the same bore and stroke except its .905" x .937" bore and stroke. The only other .61s I have are a Merco .61 and an Italian made SuperTigre ABC .61. One of my big regrets is that I'll never be able to get those kinds of engines again. Woops, sorry for the whine.
