Frequently Asked Questions
What propeller size works best with the ECOII 2004 3000KV?
This motor is optimized for 3" to 4" propellers. On 4S, 3" props deliver punchy freestyle performance, while 4" props on 3S-4S maximize efficiency for long-range flights.
Can I use this motor on a 4S LiPo battery?
Yes. The ECOII 2004 3000KV performs excellently on both 3S and 4S LiPo batteries. On 4S, stick to 3" props to keep current draw and temperatures within safe limits.
Is this motor suitable for sub-250g builds?
Absolutely. At 11.3g per motor, the ECOII 2004 is a top choice for sub-250g drone builds, helping you stay under regulatory weight limits while retaining strong performance.
What ESC is recommended for this motor?
A 12A-20A BLHeli_S or BLHeli_32 ESC is ideal. Many builders use a 4-in-1 ESC stack rated for the appropriate amperage on their chosen battery and prop combination.
What is the mounting hole pattern?
The motor uses a standard M2 mounting pattern with 16x16mm hole spacing, compatible with most 3" and 4" micro quad frames available on the market.
