After turning on truck .an go to accelerate the truck hesitates an makes a "Brake sticking sound wen throttle is applied. .on the Traxxas Summit. .Thankyou!

This is a loss of fuel pressure and it could be either the fuel pump in the gas tank or the throttle sensor in the engine.

Sounds like your accelerator pedal or linkage to the throttle body or carburetor might be sticking.

Most common problem is a failed mass airflow sensor. Remove sensor and carefully inspect the sensor for debris building up on the diode. Another possibility is the egr valve may be partially stuck open. The upper intake manifold is made of plastic. The egr gases enter the intake just behind the throttle body inside the plastic intake. It is pretty common for the hot exhaust gases to burn through the plastic and possibly cause coolant to enter combustion chambers. A restricted catalytic convertor from previous engine misfires will accelerate this due to exhaust gases having no place to escape.

When you passed the truck... I guess you couldn't tell if the pedal was stuck since you were focused on braking.

When you brake, your brakes will overcome the acceleration of the car causing it to slow down, but like you describe, the second you let go of your brake, your car accelerates again.

It would sound like either the throttle pedal (gas pedal), the throttle line (connects pedal to throttle assembly) or your throttle assembly (on the engine) may be sticking....

throttle and linkage are sticking, use silicone lubricant spray , apply to both, manually work the throttle and linkage, re- apply,

your fuel injectors are clogged

i would try cleaning mass air sensor, its mounted in air duct between air filter and throttle body, they sell the cleaner at auto parts stores, also as stated bofore make sure the intake pipe clamps are tight and it's not cracked, if that doen't fix it i would investigate a fuel pressure problem either a weak pump or problem with regulator

check throttle position sensor!! at throttle plate on side of throttle body.

sounds like an air flow meter problem. or injectors may be blocked. have you run injector cleaner through it? may also be fuel pump?

sounds like unburned fuel in the catylistic converter suddenly burning the fuel as your car picks up speed [causes the rotten egg smell] your hesitation sounds likley to be [tps sensor] throttle position sensor its a variable resistor which is known to breakdown not a difficult repair and can be tested on a multi meter with a bar graph on it yates210456
