Q: Is the EMAX ES08MA II programmable? A: Yes, the EMAX ES08MA II is programmable, allowing users to adjust settings such as throttle curve, brake strength, and timing.
| Symptom | Likely Cause | Fix | |---------|--------------|-----| | Jittering at neutral | Deadband too narrow or dirty pot | Add small deadband in software (e.g., ignore ±5 μs changes) | | No movement, buzzing | Stalled or voltage droop | Check power supply: must deliver >1A peak per servo | | Inaccurate positioning | Worn potentiometer | Replace servo (pot is non-serviceable) | | Overheating | PWM frequency >100Hz | Reduce to 50Hz | | Gears grinding after crash | Stripped internal gear | Replace gear set (available separately) |
