    WOW!!![:0] You havent changed your glow plug in a year????[:0] I think its time to change it. You should change your glow plug after at LEAST like 2 months. You should get a hot plug. Crazy as it is it will make your engine run cooler. Now if you had a big block engine, you would run a cool plug. A big block is anything over an .18 engine. Now let me explain. A hot plug burns hotter, so your engine doesnt have to work as hard to ignite the fuel, therefore as your engine works less hard, it runs cooler. Hope that helped

    your best bet would be to change it and also change/charge the battery to the ignitor, this will make sure when you get your new plug and as long as the engine is tuned right it should fire right up!

    There are short and long plugs. Ask your hobby shop what one you need.

    Come to think of it, you should probly buy an extra plug, just because there such routine replacements. But I just cant get over that your plug lasted for a year!

    well if it is a rs4 and your running a stock .15 the short would be your best bet to go with, and make sure it is a hotplug also.

    I noticed that the .15 runs with such low compression to begin with a long plugs actually helps. Might need an extra washer between your plug and head, but I don't have one. But I just bought mine (and replace the motor already... long story), not sure if the old .15's are the same as these new ones are.

    Try going with a long hot plug , keep in mind that .15 motors and below run there best with hot plugs if your running 20% nitro, .21 motors or larger motors med. heat or cooler plugs, RED
