請問12仔用3.7V Lipo電會用幾turn brushless?

我用2cell Lipo行8.5T，23/96齒，Speedmind呔，直路唔快，但勝在夠線性。

師兄，其實我諗應該係咪要睇埋隻魔打嘅Kv值呀。RPM＝Kv×V
用Novak 8.5T，Kv＝5000，用1cell 3.7V RPM＝18500 RPM，用2cell 7.4V RPM＝37000 RPM
用好盈 8.5T，Kv＝4000，用1cell 3.7V RPM＝14800 RPM，用2cell 7.4V RPM＝29600 RPM
再計埋Roll Out嚟揾個靚仔嘅Gear Ratio末得囉。

點解唔用30C呢？

If my calculation is correct;
assume your 4.5T motor has 9000Kv, with 4.8V you'll get 43200RPM,
with factory recommanded rollout, max speed equates to 79.05Km/h

if using 3.5T, 10500Kv at 3.7V, you'll get 38850RPM
with factory rollout, max speed around 65.35Km

May need to sacrifice heat and accelaration when re-gearing to the same speed
