(Part: 1/3) Custom Zenoah G270RC Cylinder head kit for my Trevor Simpson engine 

I have been a CNC and manual machinist for all of my adult life, over 35 years now, (and have been building TS reed cases engines, and winning, for over 15 years now), and I have to say, you have turned your drill press into a light duty mill. One problem you may have though is "heat sinking" , (what a overly hot engine is called, as it loses power). The Sikk toys/CY 29cc RC kits had this problem because the head dome did not interface the head shell very well, (has air gaps). The air gaps between the cylinder and the fins will not transfer the heat as well as it could to the fins, so the engine over heats and loses power after a few min of running. Higher compression makes the problem worse, as it generates more power/heat. I once did a interview for a little job machine shop, and he had me cut a morris tapper on a manual lathe. He knew the taper was cut correctly when he slid a larger morris taper adapter on the hot freshly cut steel, (cut with HSS tool, puts more heat into the part than with carbide cutting tools), and the adapter instantly got hot. He told me it was a good taper because if it was not, it would not have had that "instant heat transfer". The same principle applies here directly. Still, I am pretty impressed at what you can do with a drill press. Like I always say, "There is more than one way to mill a cat." :) Doug @ ESP (Earth Surfer Products)

Thanks! The best way to solve the cylinder-to-cooling fin heat transfer is using thermal conductive paste for filling in the small gaps.

Could you make these for boat motors please comment back they have to have cooling thank you very much

Just search ebay for a bearing with an outer diameter the same as cylinder bore.

I would love to have custom cylinder services available, but it would be more trouble and time consuming for a reasonable cost.

@@TheNoisePolluter .....yeah that's understandable and true too , over all the motor looks like art man your do great work , I bet that motor sounds like a angry beast

Yes, you'll see it running in a video where the whole engine is put together.

Use the ADA G290RC head kit with the red Loctite 518 gasket sealer on the copper gasket...You just rub some sealer between your thumb & index finger and dab the copper head gasket leaving red finger prints all around it(safe amount needed) and that'll carmelize and seal everything tight.

@@TheNoisePolluter well unfortunately ADA doesn’t have any of the 290 headkits in stock i was already trying to do that im all set with the cy29. Gonna have to try and find a headkit preowned. Thanks for the tip

Do you mean puting and air cooled top-end for use in an RC boat or a reed ported watercooled top-end? Because, a reed ported air cooled engine will over heat in a boat.

@@TheNoisePolluter I'm just looking to get more horse power of the 2 motors that I have how can I do that I will also have a Quick Draw in a boat how could I get more power out of these 3 motors please comment back I have water pick up in the rudder in also in the bottom of the Boat so let me know what I have to do

Mark Francom The compression ratio is 15:1
