Hey guys. Im new to the forum and am not a physicist or engineer. I have an RC model car and im wondering how I can get the exhaust to produce flames. the engine is a .28 cu in (4.6cc) 2-stroke, no spark plug it uses a glow plug, it runs on a fuel mix of 20% nitro, around 16% oil and the rest methanol, normal engine temps are around 250 degrees celsius. If you need more info just ask. could it be that exhaust temps are not high enough to re combust unburned fuel? or the type of fuel? Any help will be appreciated, cheers.
