I took my new Stalker .81 out toda in my old Red Impact, The engine seems to fly it pretty well. I used 10% nitro with 20% oil 5% castor, 15% low viscosity synthetec oil & a 12- 6 , 12.5- 6 prop 7900 rpm. I runs fine & holds a steady speed, lotas torque & doesnt speed up in manuvers. Any thing I need to do to improve it? I think I only have one venturi & didnt measure it.
Any ideas? John
