I Follow this Forum since July and im happy to see so many  Enthusiasts in radial engines. Im  also a proud owner of an ASP 400 from hobbyking. so far so good. I struggled a little bit to get all cylinders running until I followed some suggestions from Tom.

Have any of yu ever heard from this machinist guy named George Luhrs ?. He built the smallest 5 cylinder radial engine for a contest sponsored by sherline tools in 2001. Unfortunately i havent seen a video of the engine running and I dont even know if the guy is still aive but is quite an achievement what he made. his webpage is minimodelengines].com  (remove the square bracket to go to the webpage).
