Default Shockwave turns off on full throttle

New to RC cars and new to RedCat Shockwave. Set the gear mesh, tuned it (best I knew how), set the appropropriate carb setting (1mm), figured out charging/testing glow plugs, and broke in the engine per manufacturers recommendations, etc (most of it by trial/error)...however the one last thing that I cant seem to figure out is why when I run it at full throttle the engine dies on me? Engine stays running on full break and everything inbetween a full throttle, but once I max it out, it dies on me. I am sure it is an easy adjustment, but not exactly sure what to adjust.

Thanks in advance for your help

Signed, total noob

sounds like you may need to adjust the high-speed needle. it may be rich, or may be lean.

is it easy to restart when it dies?

If the motor idles well, and has good low-end power then the idle gap and low speed needle are set pretty good.

It can also be a bad glow plug. sometimes they will still light up when you test them, but not give enough heat to run 100%

but 1st try tuning the high speed. make small adjustments, and remember where you started.

after you make an adjustment, do 2 or 3 high speed passes.

also, when you hit full throttle...just before the motor dies...is there a good trail of smoke coming from the exhaust? If not, then the motor is lean and you need to richen up the high speed(turn counter-clockwise)

When the engine dies at full throttle it is usually because the engine is too lean. Try turning the high speed needle counter-clockwise a bit. Keep in mind that the engine will run leaner as the gas in the tank decreases. You should be able to tell the difference when you have about 1/4 of a tank left. So if you make adjustments when the tank of nitro is between half and full and you find a good setting, you might find yourself running too lean towards the end of the tank.
