Team-blacksheep have very nice frame for DJI-NAZA with some fancy PDB, but I don't have NAZA and I wanted some modification to mount APM2/2.5, so here is my version of that frame, no fancy PDB and PCBs, just black fiberglass :)
If you do have DJI NAZA go get that frame right NOW !
APM2.0 with 90° pins fits under the top plate with analog and telemetry pins exposed.
APM2.5 with ublox GPS.
Set the LED_MODE parameter to 9, It will slow blink when disarmed, solid armed, fast blink + beep on low battery.
The CG and the APM location moved a little bit, but it can fly as regular X quad. (don't pull back too much)
I just changed the AP_MotorsQuad.cpp X frame set-up to:
add_motor(AP_MOTORS_MOT_1, 55, AP_MOTORS_MATRIX_MOTOR_CCW, AP_MOTORS_MOT_2, 1);
add_motor(AP_MOTORS_MOT_2, -125, AP_MOTORS_MATRIX_MOTOR_CCW, AP_MOTORS_MOT_1, 3);
add_motor(AP_MOTORS_MOT_3, -55, AP_MOTORS_MATRIX_MOTOR_CW, AP_MOTORS_MOT_4, 4);
add_motor(AP_MOTORS_MOT_4, 125, AP_MOTORS_MATRIX_MOTOR_CW, AP_MOTORS_MOT_3, 2);
Setup
Motors: Tiger MS2212-13 980KV
ESC: jDrones 18A (Flashed with SimonK FW)
I really like the 10X5 Graupner e-props (or new Carbon 10X5 e-props) with 4S 3000mah lipo, after some fine-tuning its very sharp fly.
Here some raw clips from Arducopter 2.8.1 tuning flights:
BTW Jani from jDrones (that where I CNC all my custom frames ;) ) has put together fancy RTF kit, so check that one out.
EDIT:
The top outside hols for the arms are ~0.5mm off, I think so chek it before cuting.
Comments
I got about the same frame but want to fly it proper, is the maybe a custom firmware available for this setup?
Uh, I really am an idiot! I measured the angles between the arms and the longitudinal axis (the red line in your drawing). This is obviously wrong...
@Markus, the angles are for the center of APM as it mounted on the frame.
Perhaps I'm an idiot but I get quite different angles from my TBS Disco than 55° and 125°. Especially for the first value which is at my Disco around 70° (the second around 129°). I cannot measure it super accurat but I am sure that quite more than 55°. Strange...
Normal 2.9 quad is working just fine with it and there is also alternative HEX file available on jDrones/jDoc site soon. We try to keep custom firmwares available for this frame.
@Isaac, you can use it with normal X quad settings.

I'm thinking that this frame looks pretty impressive.

It it necessary to change the code to get this frame to work or would it work with the default V quad settings?
Looks good. I too am working on a clone version of the TBS Discovery, only mine was a bought clone and Im using multiwii on the Flyduino Mega Board, GY-86, GPS, er9x flashed TX, SimonK flashed ESC, all my software is open source! My Quadcopter Build
Nice job, and thanks for sharing the DXF. Are you going to try AC2.9? I'm curious how well 2.9 works with hard mounting.
