A typical 5-inch on a 1300–1500 mAh LiPo is done in four to six minutes. The same airframe on a Hyperflux Li-Ion pack is not “a bit longer”. It is a different session, as long as you are not racing full throttle the whole time.
Ballpark times we actually see
| Build | Pack | Energy / weight | Typical flight |
|---|---|---|---|
| 4S cruiser / efficient 5-inch | 4S1P 5000 mAh | 72 Wh · ~300 g | 10–20 min |
| 6S 7-inch long-range | 6S1P 5000 mAh | 108 Wh · ~445 g | 15–25 min |
| Heavy 5-inch / cinelifter 4S | 4S2P 10000 mAh | 144 Wh · ~590 g | Often 2× the 4S1P |
These are cruise-biased flights, not gate runs. A thirsty 6S 5-inch on 1P will still be current-limited; that is when you step to 4S2P or stay on LiPo for the race pack.
Why mAh lies and Wh does not
5000 mAh at 4S is 72 Wh. 5000 mAh at 6S is 108 Wh. Same “milliamp-hours”, 50% more energy on 6S because voltage is higher. All-up weight and hover current decide how fast you burn those watt-hours. The Hyperflux 6S1P is ~40% lighter than a typical 6S 5000 mAh LiPo, so more of the 108 Wh goes into flying instead of lifting the pack.
How to make the time show up
- Efficient props and a cruise throttle, not a 100% punch-out.
- Land by voltage, not a LiPo timer. RS50 cutoff is 2.5 V/cell (10.0 V on 4S, 15.0 V on 6S). Do not dump to cutoff every flight if you want cycle life.
- Keep packs warm. Cold Li-Ion loses capacity and punch until it comes back up.
