Exclusive summary about Glow Plug for Nitro RC Car by Gregory Alexander


Selecting the correct glow plug is not that difficult you just have to understand how they work. Truth be told they are not exactly perpetual motion machine, they still require a little kick with a 1.5V battery to start the glow, after that they will keep glowing as long as the rc car engine is running.

The glow plug temperature rating

You need to find the right temperature glow plug for your nitro rc car engine, a hotter plug will work better when the engine is a little short of heat, while you should use a cooler glow plug if you have a large engine that produces a lot of heat.

Reading your glow plug

If there is a surplus of oil on the head then they are running to rich and need to lean up your mixture, if your glow plug is a grey color with a small amount of oil then your spot on with your tune, likewise if there is little to no oil and your glow plug filament is bent or thinning where it connects to the base of the glow plug then you are too lean and need to richen your mixture.

Some general points about glow plugs

  • Never touch the filament, this is very fragile and doing so can break the filament and ruin a plug.
  • Protect your engine by only buying good glow plugs from decent hobby shops
  • Keep your glow plugs in a cool dry place, they don’t like moisture
  • Always select the right glow plug
  • Follow the recommended break in procedures for your engine.
  • When breaking in an engine chances are that the plug you use will be ruined.
  • Keep your engine in tune
  • Never tighten a glow plug too much, it doesn’t need to be as tight as you think
  • Watch out for nitro detonation, this means your using the wrong plug or your tune is way off.
  • Use the right glow starter

Do A Glow System Check for RC Engine Issue

Exclusive summary about Glow System Check for RC Engine by Shareen Aguilar

RC cars work pretty much like how big cars do. You just need to check each part if its working properly and if it is not, you are going to end up with enough troubleshooting up your sleeves. The glow system has its glow starter. Next, check if all contact surfaces of the glow starter going to the coil are cleaned up. The glow plug is plugged to the glow starter and when it comes in to contact with the coil, it emits an orange spark. To prevent this from happening, you can check this part of the engine periodically. The next time you have an engine problem, don’t forget to check the other side of your glow system.
