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 !

3689498526?profile=original 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.

  • I have got a couple of new 4S 3000's about somewhere. I might try this design

  • What sort of flight times are you getting with 4S 3300 lipos on this design ?

    I have always used the Chinese motors. Are the Tigers any better ?

  • Hi , where is the CG for this quad , i cant find it ?

  • hey, which software are you using to make this scheme ? https://api.ning.com/files/mzLbifxKbCTiun7OSDPnnT-dix5HL*wpJynWItZtgWfknCCW14jIlsw76HmI6B1XJj9jfTR3Gq-q2FC9hBhVcXasuU8JEVQQ/leds01.jpg?width=700

  • Just finished by TBS Style Discovery frame based on the DXF published earlier

  • Hello everyone. I was wondering if 1.5mm thick carbon sheet would be strong enough to use for a build or should I use 2mm?

    Cheers.

  • The marks are on the bottom plate for C of G. There is a little leniency here though. It's set up for the cam to be on so you'll have to balance up once your set up is almost built. Your battery weight doesn't seem too bad so can't see there being an issue to be honest. I've extended the arms on mine and upped the power and battery size. Had to enlarge battery bay by 2mm to get the batt I want in. Ill play around at the front to balance things up later. I'd still put the APM where the naza marks are.
  • Ok so my APM is a little closer to where the core would go, so I can set it back but that still puts most of the weight at the back...

    Currently with a padlock as counter weight in the front it balances a the back arm front screw holes.. Is that consistent with your builds per se?

  • There are six holes in the frame looking from the top.
    I put my spacers in the last two holes between the legs.

    Just behind the spacers is my battery and just before the spacers is my APM.
    I wouldn't put too much load on the back motors as in case of emergency you would need some extra power you just might run out of it. So I keep the weight balanced as much as possible between front and back motors, even if I need to put some extra weight in front.
