Back with Ys-X4 Octo and Foldable Y6

Hi ,
It is rather busy time for last few weeks. Now it is time to get back to my hobby: built multicopter.
This time I start with Ys-X4 since it is new and good price 650USD for full navigator version ( 8 way points unlimited distance).
First it come to my Overlap Mikrokopter Octo as required from my friend. He like to YS-X6 since it is more simple to setup and control by his Android phone. I post to sale the MK electronic for that requirement. However the YS-X4 come so I give it a try with this OCto electronic replace ment and also my new foldable Y6 which also modify my old design frame.
The Ys-X4 Navidation version is good, the case of FC is make from alu (Why???)  so it rather heavy.

I bought 2 of this from Himodel.

I did replcae the Mk electronic with thsi Ys-X4 and give Octo back to my friend, and forgot to take pics. I will update it soon.
