ECO 8 power setup recommendation

I have my reached sustained tail in and side in hovering phase on my ECO 8, and contemplating what power system to go to for long duration. My current 8 cell 3000 mah battery provides 8 min on brushed motor. Most favorable seems to be MEGA 22/20/3H with CC45 with 10 cell 3300 NiMH.

What setup do you have in your ECO and what “sport” flying duration do you get?

The 220/20/3H is more of a power setup. You won't get good duration.

The max duration I get on a 22/20/3H with 10xRC2400s is about 7 mins of kinda weak power.

The 22/20/4 is much better for duration...I get about 10 mins of good duration on the same cells. See the EHBG for the pinion size.

See this thread:

The 22/20/4 actually gives about 10 mins of duration. In the above thread, when I tested the 22/20/4, the ECO 8 had a bad bearing which I didn't notice till later.

22/20/4 on 10 cell 3300 should be 13 min. Thanks for the extensive testing with all the motors and specially EHBG. I have been following it ever since I restarted learning helis.
