Good number! What's she do with an APC 11 x 7? I'm guessing somewhere in the low 14s.

That's really good for a 1/2a engine!

I'll have to check my invantory if props and see if I have one. This is the first engine I've tried to "go fast" with so I started with the 10x8. I have a bunch of 3D props that probably won't like the pipe.

The engine is very used. So yes, it is totally broke in. The piston is actually brown in color instead of the normal dull alluminium. I imagine it starts out kinda loose and does not completely seal until up to operating temperature.

That's not bad rpm! I'm impressed with my OS 55ax though. With a better than stock (tower hobbies .46 $15 pipe) non-tuned pipe she turns an APC 10x8 @ 14,250 on 10% Omega. Nice to see the .61 turning large RPM, though for the weight trade-off I'm happy with the 55ax.

Considering its very used and is developing 15k , I think I need to give a chance to this engine in the future. My Rossi 53 is able to develop just 500 rpm more with the same prop.

Good job bro !!! [8D]
