Default .50SX Break in prop

Does anyone know the correct prop to break in a .50SX? I currently only have a 12.25x3.75 or 12x4.

11x6 ~ 10 , 12x6 sport
12x7 ~9 aerobatic

This engine looks exactly like my .46fx , good luck with I had a hard time not having the nose bleed on the carb.

Either prop will actually work out fine for you.

Just follow the correct break in proceedure for a ringed engine.

Run it rich in the beginning and use some caster oil in your fuel.

Enjoy,

I was going to use a 12x4 on OS 50SX for 3D so I just broke the engine in with the 12x4 on it. Just run it really rich at the beginning and you'll be fine. I had to lean out the low end on mine to get a nice transition from idle to full and its just now starting to bring on the power.

A non break-in tip:

Try a Tower muffler once she is broken in- the best performance mod. for $15-

My SX is QUICKLY becoming my favorite engine, and I have/had quite a few--
