I have the Novarossi RR12L5 long stroke engine fitted to an Fw-05 with JPL 6mm pipe.
I'm running 16% Nitro and a No 5 Novarossi plug. The head clearance is 0.018" (It has a 0.3mm shim in)
The engine doesnt seem to have any top end power. I have toi use the lowest top end gear to get it to rev out. If i use a taller gear it doesnt get to top speed.
I need about a 15% increase in power. Anybody have any idea what could be the problem? Motorman?
Cheers
Im no motor master, but I have some experience with this engine.
1st, pls stay 16%, its enough for this engine. I assume the motor still in good condition.
Why you using no.5 plug ? is the engine only performs well in very hot condition ?
