Very good replacement for the original peeling crappy OS liner in the 46FX.
Nice pinch, but not overly tight. Runs better than it ever did with the original OS crap in it.

This is the answer I was waiting to give you all , because like you, I was also in doubt.
So, I ordered one and received mine some days ago.
And ....... YES this set fits perfectly on a OS 46 FX .
The cilinder fits perfectly. You can buy it with no error.
Now, lets wait for the weekend and see how it works in the field.
Just to mention : mine is a FX . Cant say if it works on a AX.

I actually need the conrod for the heli engine as the piston fit was tight and it wore the big-end bush a bit so now after i sanded the piston to get it loose there is no compression after she has run but its a great engine makes lots of power 13X7 APC prop @ 11000 Rpm in a .40 size plane

Does NOT fit OS AX .46. I tried and it is too small. Works perfectly as a replacement on an ASP .40 engine. So don't buy if you are planning to use it on a OS AX .46.

I upgrad my old ASP S40 to new ASP S46, same stroke and same bore for cylinder outer caliber. ASP46 have thinner wall of cyliner compared ASP 40. Channels for cyclic flush the same as to ASP40. This upgrade I bought for more power.
