Engine Performance
 

Hey Guys,,,got any recommendations if any,, on;;;I'm trying to get a lttle more pwr out of my Magnum 52 4-stroke...

what fuel and prop are you using do you have any rpm numbers? that can help us determine if your engine is performing optimally also what plane is it running on that can also help you determine what size prop you need?

Make sure you have an OS-F glow plug installed, run 30% nitro fuel and the correct prop.

Other than that, buy a larger engine.

I just this week bought a gallon of 15% fuel and it was $25.00. I shudder to think what 30% fuel would cost, but whatever it is, it would not take too many gallons of it to pay for a larger engine. Nitro is EXPENSIVE.

It's a 40/45 size Slow-Poke,,i'm swinging a 11x6,,,15% nitro

Try a 12x5 or 12x6 APC prop...that would be your least expensive first option.
15% nitro should be sufficient. 30% might get you a little more performance, but the added cost???

I'll try the 12x5,,,,maybe I can bum a tank of 30% just to see how it tachs out or not,,,Appreciate the tip
