Default RE: Engines Comparison

OS AX 1.20 and I wish to know the tach readings and behavior of this particular engine.
Thanks again for your help.
Hi!
I have this engine and gets 9700 RPM on 16x6 or 8500 on 17x6. Easy to start, runs great and a very practical muffler. Maybe the muffler is the best reason to buy the O.S AX 120. It will most likely fit under the cowling on the CG Ultimate ( I had one...). Weight of the O.S A.X is actually 870 grams / 31 oz.

Trimming: Runs great with O.S "F"-plug, removed baffle and headshim. 15% nitro.
