RE: NEED HELP!!!! TURNIGY 50CC GAS
I have one of these engines and was having problems with RPM's also. The problem was the rotary valve was warped (from the heat treatment) and had to be ground flat to less than .0003". Also the large end bearing fit was .003" undersize and caused the bearing to fail. This is just my 2 cents worth

RE: Seeking CAD designer/ Machinest.
What kind of parts are you looking for? Will a rapid prototyper work or do you want the parts machined and what type of material will it require.

RE: NEED HELP WITH ENGINE
What is the best glow plug for this engine? I am also new to the glow scene and can't seem to make the thing run for more than a few seconds. The engine is inverted and I'm wondering if this is also part of my problem as the tank is on center line with the engine. Any help would be greatly appreciated
