All I ever saw was people cussing these engines at our local flying field. I had a FP .40 and I gave it away. I never looked back to sleeved engines.
The LA's are dependable flyers.
The bleed valve works backward from what most people are used to, and frequently does not let you lean the engine out enough.
I had to open the bleed hole on mine a little with a small drill bit to get it to a suitable range, but it still runs a tad too rich.
That said, if you don't know how to tune them I can imagine that people would curse them.
However if you are aware how, they work great, especially considering the price.
The LA .46 is a great and dependable .32 engine!
