CamCruiser reloaded - M4 + Quatos

[aBUGSworstnightmare]

Hi,

let me start a new build log on a second CamCruiser that is under construction. This one will use a M4 instead of the AQ6, different motors and Quatos instead of PIDs.
Will continue to post in 'picture book style' since I will need the weight of all components for Quatos later --> you will see my kitchen scale quite often

Let's start with the heart of the new copter - my new Mav2Telem 0r2 'main board'. It's similar to the one I'm using in my other CamCruiser, except that it now features an expansion connector and carries an M4 adapter PCB.

M4 adapter PCB for Mav2Telem 0r2 - M2 plastic screws will hold the M4 in place

Mav2Telem 0r2 top view - the expansion connector holds all relevant signals, including CAN (for future use).

Bottom view of the mating M4 adapter board. This features connectors for 2 additional PWM signals, Spektrum TM1000 telemetry transmitter, a second Spektrum Sat, uSD card, VCOM LDO, ...

M4 connected to the boards. In case of the M4 beta boards (M4r4 and M4r5) only the CAN bus needs to be connected to the main board, for the M4 V2 a second wire is needed to sense the LiPo voltage (since V2 has integrated LiPo voltage divider) --> swapping the M4 between frames is quite easy!

For those asking their selfs what this board is good for:
- 5V/3A switching DC/DC, Vin = 42V max.

- 12V/1A switching DC/DC, Vin = 42V max.

- 3.3V/0.5A DC/DC (LDO)
- up to 8 powered CAN slots (4 on TOP, 4 on BOT)
- 5 IntelliLED WS2812B ports for signalling 

- MavLink input (via expansion header from M4)

- Spektrum X-Bus interface for connecting to TM1000 and/or other sensors (simulated telemetrie sensors)

- HOTT telemetry output 

- Current sensor input (for use with current sensor on external PDB/breakout board)
- Arduino ProMicro socket for ‚Mav2Telem‘ project

The M4 expansion boards adds:
- 4.2V LDO for VCOM (supplied to the M4 via M4's expansion header
- uSD socket
- Spektrum sat connector for 2. sat receiver
- TM1000 connectors (data port, voltage sensor) to simplify wiring

Very intereste in the new board. I purchased the version one of the board and am just wondering if I could adapt that to the M4 with the m4 expansion Pcb that you have here?

Ok thanks for that, can't wait to see you progress. I'm thinking of building a 250 size quad for fpv, and will use autoquad for it. Just work gets in the way of fun that's all

Hi,

bad weather outside --> time to build something

Final testing of the 'FC' before mounting everything inside of the frame

CamCruiser CFK frame weight

Front arm completed with motor. Final arm weights (for QUATOS) need to be calculated later.

Rear arm weight

'No guts no glory'! During the assembly process.

Frame closed - still a lot of work to get it done!

ESC32 zip-tied to its position.

Cleaned up the mess

Controlling the weight

T-Rex 600N landing gear weight. Need to figure out how to add this into QAUTOS. Think Point-Mass will be best.

Used this to protect the motor wires: http://www.freakware.de/en/p/gewebe-sch ... a19858.htm

Prop mounts: CW and CCW

Tarot 4006 motor (without connectors)

PA017 CW prop adapter

Graupner e-Prop 12x6

Putting everything together

Side view of the Tarot motor mount with signaling LED PCB

Total wiegt of one motor assy - will be needed for QUATOS

Calculating the arm weights:
Front arm = 150g - (145g - 9g - 21g) = 35g
Rear arm = 156g - (145g - 9g -21g) = 41g
O.K. would have been easier if I didn't forgot to weight them BEFORE mounting the motor assy

Hi,

how should this be entered in the XML File for Quatos? I mean there is only one mass for arms, but we have here different values.
Is there a possibility to define different weights for the front and the rear arms?

Some more weight watchers pics:

Mav2Telem board 0r2 incl M4 adapter board. Weight includes mounting hardware!

M4r2 added

Compare weight of 1st rev Mav2Telem Board + AQ6 (not including mounting hardware!)

Frame cover plate. I'm not sure atm if I will use this one or the open one. Closed one has better possibilities for securing the LiPo

GoPro mount. No gimbal during testings!

MK GPS shield with Taoglas 35x35 active GNNS antenna

MK shield is left-over from first CamCruiser build (viewtopic.php?f=38&t=2920&start=20#p18707); it is lighter as the current AQ GPS shield!
