There are two main factors in making an engine start. First, the glow plug must be working. This means that when 1.5 volt is applied, the filament will burn a bright orange. A bad glow plug will not generate enough heat to burn the fuel/air mixture in the cylinder. Second, the engine cylinder must have the correct fuel/air mixture when cranking the engine (via pull-start or bump start). If there is no fuel in the cylinder, the glow plug has nothing to ignite. And if there is too much fuel in the cylinder (i.e. flooding), even a new glow plug will not have the energy to burn the excess fuel.

My husband has atraxxas rc truck, he replaced the glow plug, it has apull start motor but still cant get it started. what else can he check/

So he replaced the glow plug. Make sure that it is seated properly and that all connections are good strong and tight. Also make sure there is a good seal on the combustion chamber. Look for leaks or restrictions in the intake and exhaust. And be sure to use the proper mix of fuel.

My Web RC - Heli I. IR - Web Wolf isn't starting up even after I charge it. The instructions are very vague. What am I doing wrong

Hi! My sister's son had the exact same problem and after a quick look over the instruction manual I was able to get it to work. I have tried all the different Airhogs and this webrc is truly a superior flying toy. You can actually control it and make it go wherever you want to after you learn how to use the trim knob. Here are my suggestions to fixing the charging issue:
- Make sure the helicopter is OFF, - the batteries are fully charged on the controller/charger - and that the charging cable is plugged in correctly. You will know when you plugged it in correctly because the little light on the controller will change from red to green or vice-versa (cant remember) - the light on the controller/charger will change colors again when the helicopter is fully charged. - I am also an electrical engineer so I recommend you wait 10-15 minutes after turning it off and the same after charging it for optimal battery performance and life.
Hope this helps.
Have a safe flight!

My revo is getting fuel light on start remote are on both motor and glow plug engine will just turn over but will not start up

You've checked the glow plug externally to see the wire get red? If so, as long as you've got fuel and fire then it has to start. My guess here is that you have either a bad glow plug, low batteries, fuel air leak or clogged pressure line. Put a charged battery into the starter. Remove the glow plug and try to start - fuel should spurt up through the glow plug opening. Now connect the glow plug and touch it to the engine. Try to start and you should see the glow plug wire glow red. (do this only for a second. Now disconnect the pressure tap from the muffler and try to start. All else fails, replace the fuel line to the carb and the pressure tap. Your carburetor can leak air through the rubber gasket . Also, Traxxas fuel tanks have a cracking problem. Good luck

The glow plug could be bad. If the motor turns over and is getting fuel I would replace the glow plug.

Nitro car wont start?

Motor could be damaged from getting too hot. I would try to reset carb settings back to neutral from the factory. The manual that came with the car should tell you how many turns out they should be. Also check the fuel lines to make sure they did not get damaged. Nitro motors normally run best at 210 - 240 degrees. Much more than 240 degrees can damage the motor. It is always better to run a little rich than lean.

The thing you put on the back of the truck will not work only the motor lite comes on but i no its not the glow plug

Have you charged the battery in the EZ Start wand? If you have is the motor turning over at all? If the motor is turning over but not firing it could be the glow plug. If the motor trying to turn over but won't, the engine might be flooded. If it is flooded remove the glow plug and turn the truck upside down. Fuel will run out of the engine. If fuel runs out of the engine, put the truck back down on its wheels. Cover the engine head with a rag and turn the engine over with the EZ Start wand with the glow plug still out. This will remove all excess fuel from the engine. Reinstall glow plug and try to start again.

Nitro engines can be difficult to start and keep running unless they are in perfect tune. This take quite a bit of experience, even the experts have difficulties sometimes Go to for web help. Or go to your local hobby shop and ask for help.

You need to get the motor tuned. I would take to local hobby shop to have them help tune. I do not know where you are located so I can not recommend one. But your local shop should help you out at no charge. If I have motor make and size I can get you the tuning specks. If you want been in RC for 20 years now willing to help.
