Can anyone comment on the ASP .061?  They're quite cheap and would suit a project I have in mind.  Please tell what they're like if you have experience them.

The ASP is the AP engine with a different badge on it. It's a cheap version of the Norvel. This engine has a bronze bushing in the case and it wore out in less than 50 flights. I had extreme problems with plugs blowing regardless of how many gaskets I used. My experience was solely based on running the engine on bladder pressure. At one time the AP engine was the only game in town due to the once defunct Norvel company. While I did admire the fits of the piston to sleeve the rest of the engine was etremely lacking. I thought this was going to be a cheap alternative for control line combat and for all the time I invested into making this engine run, I could've bought a Norvel and still have been running one to this day. I also made a adapter for the case to utilize a TD venturi and needle valve. One setup used the stock needle while the other was an enlarged venturi which used the Kustom Kraftmanship version. The numbers when this engine was running was pretty astonishing. I never quite saw the same numbers as a Norvel, but it was close. Ken
