I've always been a sucker for different looking multirotors. After designing bigger frames I decided it was time for something smaller so I came up with this small (120mm MTM) brushed vtail quadcopter.
It's designed to use Beef's Brushed Board but will fit any FC with the dimensions 32x32mm or smaller. The frame only fits brushed 8.5mm motors.
My setup is a bit on the heavy side. 75gr AUW with a 500mah 1S battery. It's not an acro frame...
Let me know I you have any questions and I'll try to answer them.
And please respect the licence...
The frame most likely needs support for the rear arms (I haven't tried printing it without).
Rotate skirt 180 degrees around X or Y axis before slicing
You'll need the following to complete the assembly of the frame:
2x Nylon spacers (M3x5mm)
3x Nylon screws (M3x12mm)
2x Nylon nut (M3)
The nylon spacers go in the front, between the frame and the skirt
You need the feet in order for the rear prop to clear the ground, two front feet and one rear foot.
If you print this you'll probably already know what to do with the electronics, some short tips though:
Make sure you use the vtail configuration in your FC's software. A quad config will probably work, but it's a vtail after all.
Make sure to place the motors correct for the vtail setup. Both CW motors should go on the left side and both CCW on the right side. You'll also need to alter the rear props to allow them to be mounted up-side-down on the motor shaft.
You'll probably have some tail wag, decrease Yaw I- and P gain to get rid of it
