How can I make a .46NT pull more weight and run faster without selling it to buy a larger one?

That kind of depends on how you've got it set-up now?
Pulling weight and turning more r.p.m.?
"Running faster" meaning flying the plane faster?
Those two don't necessarily go hand in hand.


I have used the APC 12.25 x 3.75 and their 12 x 4 props with a Tower / Aquacraft muffler running on 15% nitro...that is a strong combination (respectable for any .46 size engine )

I meant the pull weight of the engine.the engine is set sideways in the plane so that thecorroboratoris level with the fuel tank.

You want a larger diameter lower pitch prop for more pulling power . Smaller diameter higher pitch for more speed. Max H.

People have been using the Tower 46/ GMS 47 muffler on them but it is out of stock right now.

You can put a Jettstream muffler on it
