I thought it might of interest to mention a new topic "Glow Plugs and Fuel". There are more glow plugs available, than the weekend flyer might realise. The subject is interesting, but too lengthy to reprint here. So just an overview will have suffice at this point. Glow plugs come in numerous heat ranges...each one for a specific set of conditions.....Namely fuel type (ie; nitro methane content, compression ratio, ambient temperature etc.) they come in short reach, long reach, idle bar. A range of configurations for individual engine designs ,including spark ignition. It is really worth reading information from websites like One Stop Rc hobbies, is comprehensive for selection and application.
Fuel is a story within itself. Methanol based fuel has the advantage of producing more power and running cooler than motor spirit but at a consumption rate of approximately twice that of petrol. While petrol is more economical for a given fuel allowance in competition, it runs hotter and has a much noisier exhaust note....can be a problem in noise sensitive areas. A lot modelers developed their own brews , subsequently banned because it was considered to be carcinogenic. I know one control line speed enthusiast whose finger nails and cuticles were disfigured due to these bug juices of his own formulas. It came to pass that an extra allowance of fuel was permitted if club fuel was used jn some events.
