Hello All,

Just an update on my engine woes. I did get a chance to run the engine with the replaced liner/piston and after an initial time of it wanting to run backwards, it finally settled down. I didn't have a tach handy, so I am unable to give RPM information. Suffice it to say that the engine runs just like it did when NIB. Lots of power and a smooth transition from idle to WOT.

Now then, right after I got this straightened out, I started to get the same issue from my second 46FX. This time, I ordered a replacement part from another Company which makes ABC liner/pistons for OS engines. After disassembling the engine, I noticed a spot on the back internal wall of the liner that had brass showing( 5mm x 2mm). I wanted to see if there will be any differances in the way the two will run and see how the new parts hold up. I'll update this thread when I fly the engine in the Spring. I have already been told that it will take a lot of break in since the tolerances are VERY tight on this particular setup.

Anyhow, wish me luck!
Don
