Hi,
I have a hot bodies lightning 2 with a .26 engine and for some reason i have burnt 2 glow plugs out in a week.
I dont know what im doing wrong?
Any Ideas.....................................Please Help
Thanks Alot

Overheating will damage the plug. Make sure not to tighten needle valve too much and avoid continuous running on demanding terrain such as grass fields and sand.

So you think i may be running it to lean?
i have rolled it a few times(HARD), Would that effect it?

If you gun the engine and it bogs down then takes off, it is too rich. If it takes off then seems to bog at top-end, you are running too lean. Running lean could do it. Here are some causes for failure:

There are four likely probabilities, five if you count old age, but yours was new so skip that. The plugs operate by using a chemical reaction with the alcohol in our fuel to maintain their heat; as the plug gets "old", it gets more and more covered up with combustion byproducts (carbon, etc.) which screws up the whole process.

Like your suggestion, LEAN RUNS is probably the most prevalent - not so much that the engine was running lean, as it was HOT. Too much heat, and the element fries and shatters, or even melts.

TOO MUCH BATTERY power is another failure mode, but gas powered cars wouldn't qualify. A battery should heat the plug to a nice bright orange or red orange color; if the plug glows white hot, it just isn't going to last. It's bad enough that we subject a tiny little element glowing hot, to the pressures of combustion. But if we add more VIBRATION to the situation, we get trouble, like what I said about grass and rough terrane. vibrations may add up to plug failure, especially in combination with too much heat.

Another plug failure mode is from FOULING. The element is very small, and located down in a well. It doesn't take much trash flying around in your combustion chamber to foul (and ruin) the plug! Aside from the obvious dirt coming through the intake or with the fuel, the fouling can come from metallic sources, usually a result from excess carbon deposits in the engine. If the combustion chamber is full of caked-on carbon, pieces of that can, and do, come adrift and end up fouling the plug!

Brilliant.
I understand it now.
What plug would you say i should use for a hot bodies lightning .26 engine?
Thanks alot for your help

Enya glow plugs take a thrashing!
