the trigger problem could be somethin wrong with your servo's or the transmitter, i'd chekc them with the car turned off to see if its going right away, if it isn't then thats your problem, if it is..no idea hombre

Take a minute or second to take off?? If take a minute, I no idea...........if second, than it must be your low speed needler.

Before you adjust your lowend try leaning out the top end first and see if this solves your problem. That is the big needle sticking up by your aircleaner. When making adjustments go 1/8 turn at a time until it gets faster and there is still smoke coming out. If that doesn't make it faster then adjust your low end. The low speed needle is on the side where the carb opens. You are going to need a long screwdriver to get to it.

Here is a simple way to check if the motor is fully broken in or not, assume you have never over heated it and the motor is in excellent condition:

first take the glow plug out (when the motor is cold) then turn the flywheel over and you can feel if it is still rubbing when you turn the flywheel over. If it is smooth and not rubbing then your motor is fully broken in. If still alittle bit rubing then it is not fully broken in yet.

Not necessarily. I have a three-year-old MT-12 that is well-broken in, still "rubs" yet produces plenty of power.

Default Carb Setting.

Last time I also mess up setting the needler. My friend teach me how to adjust it. Below are the step:

1,rich all the needler - low, high and make sure your engine can ideling
2, lean the low speed needler until it can't choch out. Mean when u press full throttle, the car can accelerate very fast without hessitate but make sure check the temp every time you lean the needler. Make sure have white/ blue smoke.
3, if u done set your low speed, now set your high speed needler. Lean it until u feel your car are very fast, make syre check the temp.
4, done high speed, set your ideling.
5, run your car for few laps and stop your car at your front for ~10 second and press full throttle see is it accerelate fast. If it still hessitate, than lean some more on the low speed.

1/8 a turn and one needler at a time.

Hope to hear a good news from u.
