I thought it would be a good idea to do a small build log of the 250 size "reptile martian II" There aren't any good pictures of the 6" size online so I hope this helpful for anyone looking to get one. I was going to build a 5in alien with 6in arms, but when i saw this for $40, i decided to try it first.
This is the (most likely incomplete parts list)
Motors: ztw sp2206 2300kv(1.5+kg thrust on 4s)
ESC: ZTW 30a HV Pro-f390 chipset
Frame...lol
Flight controller: Naze rev 6 (6050 version)
Receiver: DTF UHF minirx
Video Tx: N/A
Camera: runcam swift
Battery: 4s 1800, 4s2200.
The martian ii comes with textured purple standoffs, but I exchanged them for black ones to give it a more"alien like" appearance.
