Here is my build of the ZMR.
ZMR250 Full Carbon Fiber Chassis.
Naze32 Acro 6DOF.
DYS BE1806 2300kv.
Emax Simon Series 12A ESC.
WildScorpion 1500mAh 25C Lipo.
The AUW of the whole setup was around 500 grams.
Awesome frame, really strong and light.
I like the simplicity of the chassis, just 3 plates and 4 arms, all solid Carbon Fiber.
I crashed it a lot, but it held well.
Sold it to a forum member here, I miss it. :p
