Thanks for all the interest in the new engine.

1. It does come high quality German needle bearing on the bottom end of the conrod that was, as Craig stated, a late in the process change we made to improve your user experience.
2. The recommended fuel of 20:1 gas/oil is a well tested mixture with years of testing behind it. As we do longer term testing with lower oil quantities we might update the recommendation. With an ABC P/L construction some of the extra oil is used as a lubricant between the piston and the cylinder. We have done some testing with lower quantities of oil with little noticeable increase in power output. Yes - there is a little extra oil on the airplane but not nearly the amount of oil from a glow engine with a 5:1 oil ratio.
3. The engines are currently in our warehouse under going final QA inspection and movement through our system. I expect they will be shipping with 10 days or so.
4. Craig Greening is the designer on the Meridian 10cc airplane and has many flights with this engine in his development of the airplane. The two products were designed concurrently to work together so if you are in the hunt for a great airplane check the Meridian out.
5. The plug is a 1/4-32 sized plug (EVOG10350) that will be available at the same time with the engine.

I hope you enjoy this new offering from Evolution. Please keep sending any questions and comments you have to this forum and we'll do our best to answer them for you.

Pete - RE the Evo 10cc
1. Will 100% synthetic oil reduce the amount of ugly black hard to remove crud in the exhaust while using "Blended" oil?
2. Is there a method to stop the muffler joints from leaking this stuff? Somebody mentioned that his came with "O" rings installed in the center section. Mine didn't. Standard "O" rings installed blow out after a few runs.
2. Is the stock muffler "tuned" for a increase in power over other designs so should not be modified in shape?
3. Is the stock muffler pressure required for appropriate fuel delivery to the regulator? Therefore should not be changed?
Note. The motor itself is a very good design, powerful for that size running gasoline and runs super good. But the exhaust is a model destroyer in the long run, even using an after market silicon exhaust diverter which does not help because of the muffler leaks in all of it's joints including the threw bolt head and nut.
