Check wiring sequence (no reverse connection); 2. Confirm voltage matches product standard; 3. Replace with a new compatible servo; 4. Contact after-sales for batch quality checkServo unresponsive (normal indicator light)Loose wiring, servo jamming, receiver signal failure1. Replug servo connector; 2. Clean foreign objects & check mechanical structure; 3. Re-pair remote control with the aircraftServo overheats with peculiar smellAbnormal power supply, short circuit, internal servo fault1. Power off immediately to avoid further damage; 2. Check for short circuit & normal voltage; 3. Test with a new servo, damaged servo is forbidden to reuseServo jams or makes abnormal noiseGear wear/misalignment, foreign object blockage, stuck connecting rod1. Clean all foreign objects; 2. Check gear set, replace if damaged; 3. Adjust rod position for smooth rotation
