<r>Semester break coming, FPV packs idle 2 months. Heard storing at full charge kills them.<br/>

<r>New build, second flight. 10 seconds in, one motor stops spinning. Bot crashes, ESC bricked.<br/>

Forum search says "ESC desync" but symptoms vary widely. My case:<br/>

<r>5-inch FPV. Tattu 1300mAh 4S 95C packs. Bought 4 last year.<br/>
<br/>
After ~50 cycles each, voltage sag noticeably worse. Pack that pulled 60A for 4min now drops to 13.2V under load (used to hold 14.8V).<br/>
<br/>
Normal degradation? Or am I abusing them?<br/>

<t>Building self-balancer for next sem. Gyro drift 1deg/10sec, falls in 30sec on pure integration. Accel-only too noisy.<br/>
<br/>
Weighted (0.98*gyro + 0.02*accel): better, still slow drift.<br/>
<br/>
Kalman math hurts. Complementary filter looks doable. Anyone implement on AVR Uno with 10min ...

<t>Building a self-balancing bot before next semester. Using MPU6050 for angle. Bench test, motor off: gyro drift accumulates fast, ~1 degree per 10 seconds.<br/>
<br/>
Tried just gyro integration: drifts hard, falls within 30 sec.<br/>
Tried just accel: too noisy, balance impossible.<br/>
Combined ...

<r>Yo guys! After mga 8 months of saving, finally na-finish ko my first proper FPV build. Sharing yung parts list and what I learned kasi maraming beginner posts ako nakikita.<br/>

Drone hobbyist ako mga 2 years na. Build my own quads from scratch, racing FPV mostly. Currently saving up for a 5-inch competition build. Sa older members, sana hindi kayo masyado mag-judge sa 'kid' username haha, andito ako para matuto.
