ECO II 2807 Stator - For 7" Propeller Freestyle, Heavy-Lifter, and Long-Range Crafts
The engineers at EMAX are always seeking ways to design the ultimate motor with brushless technology. In their efforts, they produced the ECO II Series, a new line of brushless motors further improving on the performance and durability while retaining the same affordability.
Redesigned from the ground up, the ECO II boasts an all new architecture. With a more rounded design paired together with thicker reinforcements, maximum durability is achieved. Finished with a reflective surface, the ECO II offers a sleek modern design destined to satisfy the need for both aesthetics and durability.
In order to improve the performance from its predecessor, the ECO II utilizes N52SH arc magnets over prior N48 magnets, allowing more powerful throttle response and higher RPMs to be achieved. More torque and thrust is generated, allowing pilots the flexibility to comfortably meet the demands of any racetrack or flight situation.
The ECO II Series marks the next evolution in affordable brushless motor technology, bringing in a new era of performance for everyone.
The ECO II Series motors feature:
A brand new design with a rounded bell and stronger attachment points for increased durability.
Fully mirror-polished finish that shines and glistens with even the smallest hint of light.
Upgraded N52SH curved arc magnets for tighter airgap and better performance.
Massive EZO 12mm bearing for unparalleled smooth operation.
Right away, this is the best 65mm Whoop I know. Not even close.
I ordered two, one is more or less stock, just the PEEK motor screws and V3 cockroach. The second is upgraded to 0702 27000kV but will go back because I like the 25000kV more because of smoother throttle response and perfect betaflight tune.
Now the but:
1. On both quads I had to replace the BeeEye for a spare one because both are out of focus.
2. the yellow props were way too loose and very brittle. I lost two on my maiden. Black, blue and red are very tight (too tight for such a fragile prop) but if you get them on without bending them, they will last.
3. why does the quad not come with the lighter frame right away?
4. PH2.0…. You know the drill.
On that price point, even after the frame and PEEK upgrade I can forgive these quality issues. Especially considering the great tune and quality FC and motors. But be sure to order a replacement cam and props right away.
This was kind of a late night lark. I'd seen this upgrade for the Mk3 for a while and pondered whether it was a gimmick or not, and I'm pleased to say it's a genuinely good upgrade. It has reduced the noise of my Mk3 considerably. I haven't noted any significant increase in print quality, but the old drone of the bed is gone and that's completely worth it.
