Burning glow plugs??

I've had about 5 glow plugs go bad in my Maximum MT. It's got a Torq .16 engine on it. Maybe i'm running it too rich?? Why am I constantly burning up glow plugs???

you did not give a whole lot of information. The only thing that would burn out a glow plug quickly is running to rich, or to lean. Look at your glow plug, if there is a lot of build-up on the plug you are running to rich, if the wire is deformed or broken you are running to lean, What temps are you running at.

Default The reason your burning glow plugs

The reason is is because all engines burn diffrently than other engines and this could be your problem you might have to buy alot of glow plugs.

I have a Maximum ST Pro with the .16 Torq also, and have went through 4 glow plugs in 6 days trying to break this thing in and get it tuned properly.

I wonder if there is something we are missing.

Anyone have one of these trucks with the .16 and want to tell us what plugs they are using.

I am a newbie, but at $9.00 a pop, these plugs are killing my pocketbook.

I am now awaiting a shipment from Towerhobbies with some generic tower plugs...I fugured I could at least get it tuned prior to spending the big money again.

From reading what has been said above, I have 2 that broke the coils and 2 that look perfect...I am at a loss...

I got my shipment in, and set the carb richer, and I am still burning the plugs out like crazy.

I have driven the truck on two seperate occassions since, and have blown out two more plugs. I can't richen it anymore without killing it.

Is there something else I can do? A Hotter plug maybe?

How to "READ" your glow plug.
OS and Turbo glow plugs go gray sooner [easier] than McCoy plugs; this is not necessarily bad. Actually when A new plug wire just goes slightly gray after a 5 or 10 minute hard run it means your very close to an optimal horsepower tune, but be careful the next step is TOO LEAN!

My rule of thumb.
1} Wire and surrounding bottom of plug wet, with like new shiny wire = rich side of optimum power 85%
2} Wire and surrounding bottom of plug starting to dry and wire starting to gray = Very close to optimum power 95%
3} Wire and surrounding bottom of plug dry, wire totally gray but not distorted optimum power 100%
4} Wire and surrounding bottom of plug dry, wire distorted = slightly lean DANGER!
5} Wire and surrounding bottom of plug dry, wire broken and distorted or burnt up = extremely lean possible engine damage!

Note: You can only "Read" your plug in a nearly new state [Wire like new and shiny] A gray plug can still operate well. But after it has totally gone gray performance can start to fall off. To test just put in a new plug and if there is no difference in performance save the gray one or put it back in. If your engine does not feel or run right tray a new plug before making major tune change's

Good Luck

Well, I don't know what happened.

While driving the truck a few days ago I was really impressed that I could drive the truck without burning a plug. All I did was take it back to original settings (Torq .16). After about three tanks of gas (with breaks in between) it suddenly stopped running and moving, really rapidly...it was a pretty hot day outside, and I hadn't been checking the temperature of the motor.

I knew it had seized up for some reason, and I was right. Upon tearing the engine apart I found the connecting rod was broken at the top where it meets the piston. I was driving the truck pretty hard and deserved to get what I got. I have ordered the parts to fix the truck, and expect my order in the next few days.

Hopefully by replacing the cylinder rod and piston I will also fix my glow plug burnout problem.
