Hi All I have a nitro thunder RC car and am having problems with it. I have checked all batteries, fuel line and made sure i've not flooded the engine but i still cant get it to start. Could it be the glow plug and how would i know this. Sorry if it seems like a silly question but i'm new to RC cars only had mine a less than a week. If anyone can help it would be apreciated.
