i just got my tornado XP today and after 2 tanks of break in fuel i burnt the glow plug.
i pulled the glow plug and it has N 3 on it.
i need to know what brand and number of glow plug i can use.
there has to be something else i can use besides paying $10 and shipping
here on line.
i just need to know what i can use from my local hobby shop.

O-yea i'm also running 20% nitro fuel.
it will run aslong as i keep the plug igniter on the glow plug but when
i remove it, it dies.

any medium heat glow plug should work, but honestly i have had really good success for OS A3 glow plugs. I believe I have also seen people mention the OS A5 as well.

A5, A3, and #8. the A5 is a cold plug, the A3 is a hot plug, and the #8 is their "medium" plug.

if it's really hot where you live (like it is here), you'll want to stick with an A5 (or any cold plug)

and tat-breakin usually beats the crap out of a glow plug, on any RC engine. after your engine is broken in, you should have a lot of trouble-free runs out of your car

thanks i got 4 a3's and it's running great.

Try A5s. With 20% nitro they should be ideal. #8s as well Would work well but I would have thought an A3 would have been to hot? Anyway alls well that ends well...

also remember if you change what % nitro to run make sure u break the engine in with the new nitro just like u did when u first got the car
