Motors
I had 4 of these cheap Eachine motors left over from my first FPV rig, the Wizard 220S.
2207 2305kv
-
Flight Controller / ESC
The “Mamba F405 MK2”. Cheapest, most reliable, stack on the market. Plus, I could get it in less than 2 weeks.
4s - 6s battery compatible
I’ll move this to my next quad when I build version 2.0!
7in Duct Build
-
Frame
Accepts 7in Props
Hollow-body, 3D-printed PLA
Includes a stator that removes swirl from exiting air, increasing efficiency.
-
Motors
Same motors from the previous build, 2207 2305kv.
Using 6s batteries and lower kV motors will help spin the larger props. The added torque will help with control as well.

Flight Controller / ESC
The “Mamba F405 MK2”. Cheapest, most reliable, stack on the market. Plus, I could get it in less than 2 weeks.
