Parts list:
- frame:
- Carbon Fibre QA250 Quadcopter Frame Kit from: http://makeitbuildit.co.uk/
- ESC:
- 4x EMAX 12a ESC speed controller (simon k firmware)
- Normally I like the hobbywing quattro escs as there is no need for a power distribution board or wiring, but even without the case the hobbysing quattro is 55g, 4 of these Emax escs are 32g.
- motors:
- 2x EMAX 1806 2280KV CCW thread motor
- 2x EMAX 1806 2280KV CW thread motor
- propeller:
- HQ Multirotor 5 x 3 Props, and HQ Multirotor 5 x 3 R Props
- flight controller:
- an old APM2.5 I had lying around
- a lot of people use the acro naze, but it is constantly out of stock, and as I am familiar with the APM installation and tweaking I opted for the APM. It is just super convenient to hook up a bluetooth module (see: here) or the 3DR radio (see here: http://plane.ardupilot.com/wiki/common-3dr-radio-version-2/) to configure the copter.
- Power:
- APM power module. http://plane.ardupilot.com/wiki/common-measuring-battery-voltage-and-current-consumption-with-apm/ This powers the APM and also measures battery voltage and current. I cut off the XT60 connector on the copter side and soldered some 16AWG cables to connect to the ESCs. No power distribution board needed.
- RC control:
- Hawkeye openLRSng miniRX UHF receiver (http://www.fpvmodel.com//hawkeye-dtf-uhf-minirx-433mhz-long-range-receiver-_g707.html)
- first time I ordered from FPVmodel. Order arrived within 4 days from China!!
- FPV:
- Sony super had 600TVL
- TS5823 32 Channel 5.8ghz mini video tranmitter here
- LHCP antennas: http://makeitbuildit.co.uk/index.php?route=product/product&path=70&product_id=138
- for recording a Mobius camera will be mounted on the vibration isolation mount
- I have not yet installed an OSD, but might install a minimOSD later. Keeping it simple for now.
Some photos of the complete build:
375g weight without battery
I only had these old nanotech 3S 2.65 Ah batteries lying around. a bit heavy at 212g.
589g AUW with the 3S 2.65Ah nanotech. It draws about 11A at hover. Only a little above 50% throttle. I am surprised how well the EMAX motors work. They are not even warm after flight. I might try 6x3 inch props.
