DMax,
Since you do not live on some uncharted desert island, why would using 5% nitro fuel bother you?
If it gives you great power, a great, low 1,800 RPM idle and a great transition, in the MVVS .49, just buy it and use it (it is quite inexpensive too)?
I would understand if it didn't, but it does.
Most plane engine manufacturers, do not recommend 30% nitro, or a pure synthetic lubricant fuel, such as CoolPower, in ABC and ABN engines.
Omega (Castor/synthetic) 5% nitro will do all you want in the MVVS, although I would recommend Model Technics and Byron fuels.
Add some BeNOL, or SIG degummed Castor oil, to get 20% total oil, for best performance and life.
