A couple months ago Rotor Riot started promoting the 'butter kwad,' a six inch alien with two blade props. Well I don't know if butter kwads took off beyond the couple of rotor riot videos, but I had been thinking about going back to six inch props.
After building my 220 martian, my ZMR250 that I flew on 3s sat in the corner. I wanted to keep flying it, but the old escs without damped light and the naze32 were going out of style. Then I saw the butter kwad and thought about upgrading the ZMR250 to 4s. With that idea came the need for new ESCs that could handle the current. I got a great deal on ESCs during one of ReadyMadeRCs flat spin sales so I also treated myself to a new flight controller.
The result is a sort of hybrid old-new tech build. Here are the specs:
Frame: Martian II 250mm
Motors: Cobra 2204-2300kv
ESCs: Sunrise Cicada 20a BB1
Flight Controller: Frsky XSRF3O
Receiver: XSR built into FC
vTx: and camera: some old Eachine 200mW set from banggood
Props: Dal 6045 and a bag of Gemfan 6045
Spoiler: I did this build over Thanksgiving so most of the build process is past events and I have already maidened and flown this build multiple times!
