Specifications

The EMAX ECO II 2807 steps up to the large 2807 stator with a wider 19×19 mm mounting pitch and KVs aimed at big props: 1300 KV, 1500 KV and 1700 KV at $26.16 each. It carries longer, thicker leads (200 mm, 18 AWG silicone) than the 2207 and 2306 versions, because this class of motor is built for 6S and heavier 5-to-7-inch setups. Check your frame before ordering: 19×19 mm mounting does not fit the 16×16 mm standard used by the smaller ECO II models.

Frequently Asked Questions

What airframe is the 2807 built for?

The 19×19 mm mount targets 5-to-7-inch and heavy-lift frames, not the 5-inch racer class — confirm your frame uses the wider pitch before ordering.

Which KV for 6S long-range?

1300 KV is the calm, efficient long-range winding; 1500 KV suits 6S freestyle, and 1700 KV is the most aggressive of the three for lighter 6S props.

Why are the leads thicker on the 2807?

Bigger stators pull more current, so EMAX fits 18 AWG wire at 200 mm to handle 6S loads without voltage sag.

Can I run the 2807 on 4S?

You can on the higher-KV versions, but the 2807 is tuned for 6S — on 4S it will feel under-powered for its size.

Does it share props with the 2207?

No. The 2807 spins 7-inch-class props, while the 2207/2306 are 5-inch motors, so match the prop to the stator, not the brand.
