Aeronavics / Droidworx Most efficient Lipo for Axi 2820/18

[DutchAerial]

I recently spook with some one from Axi motors and he told me that the upcoming Axi 2820/18 motors will have a lower KV then the Axi 2820/14.
From this a conclude that they ment for using with more cell lipo's?

Revering to the Droidworx Skijib lite setup, how many cells lipo would suit best for these motors?


Any efficiency tests done by Droidworx? Thanks!

Also recommended are the Tiger Motors MT2515-15 . These motors seems to want 5s or 6s. But Droidworx says in this guide that 4s can be used. Is this still efficient? http://droidworx.co.nz/assets/SkyJib8Lite-Cinema-SetUp-Suggestions.pdf

I think the lower KV will be for the Gemfan props. The combination is supposed to be more efficient. Maybe DW will chip in here
