Need more info or a picture of your set-up? Sounds like you need an adjustment on the carb or an issue with one of the fuel lines...

When you look down into the carburetor with the breaks applied is the opening closed or open? You may need to adjust your low speed needle. It sounds like it is starving for air. Sometimes from the factory the settings can be off. Check your manual and you may have to reset them.

Temperature and weather play a big part in tuning nitro engines so you may have to tune it often depending on where you live.

But humidity plays into it too. Check the carb and if you can post a picture that would help. It sounds like you need to adjust it on the low speed needle side.

Oh and mine was doing the same thing. look at the tube going to the muffler. mine had a hole in it and i replaced it and it works fine now.If thats not it then look at the carb or glow plug. both of those have happned to me also.

What Charlie said makes sense. Make sure the pressure tube from the exhaust to the tank is clear, free of holes, and fits snug (preferably with a fitting) into the exhaust. Did you replace the glow plug after break-in?

Your manual should tell you which way turn it if CC does not know and it should be the low speed needle. Also if you set the car on a box so the wheels can spin freely and fire it up you can adjust it that way too so you know it is right. Also it is best to do it when it is warmed up a bit. You just want to make sure the motor does not get loaded up and hyper lock or flood it. RPMs are your friend with nitro motors to keep the cylinder clear of unburned fuel.
