Brushed Motor with ESC Full Throttle Issues

hello,

i using arduino uno hobbywing quicrun 1060a esc , traxxas titan 12t brushed motor. able arm esc , power motor @ lower speeds properly, when attempt raise throttle full stop above 67%, or 1700 microseconds, motor continuously cycles @ lower throttle. issue seems occur more when vehicle under load, not make sense. also, when switch lower throttle level higher level (above 67%) without delay of 1000 microseconds, have same issue of motor continuously cycling.

is there issue delay times using between changing throttle levels? esc not capable of rapidly increasing throttle when under load? there chance arduino source of issue?

here code using , have issue with. in advance!

code: [select]

#include <servo.h>


 

servo motor;

void setup() {

  motor.attach(9);
 
}

void loop() {
  delay(4000);
  motor.writemicroseconds(1500);
  delay(1000);
  motor.writemicroseconds(1800);
  delay(1000);
  motor.writemicroseconds(1000);
  delay(2000);
  motor.writemicroseconds(1500);
  while(1){
  }
 
  }



maybe current-limiting?  have tried controlling direct servo-tester?
