The idea
Make a quad copter that can make pictures
- so stability is preferred over stunting
- would be nice if I could add auto navigation, but this is not required
- want to control the camera from the ground
- budget ~250 euro
Related and inspired by:
To do
- Gather info about comparable quad-copters
- Estimation of the weight, and figure out which parts are needed
- See which camera would be suitable (programmable simple lightweight cam)
- Design the frame
- Order parts
- Make the thing
- Learn to fly
Parts
Below some mind blurbs. A list with parts, the weights, and costs is here: Parts-NarCopter.ods
- Body/frame (DIY)
- Choose build and material: printed, wood, and/or carbon frame
- Models Thingiverse
- Carbon 4.50-8.50 euro per meter Muco
- Flight control board, with integrated camera control (gimbal and push-the-button support), and with GPS support
- Comparison flight controlers
- Crius all-in-one pro - $57.50, GPS has to be bought separately ~$30
- MultiWii pro 2.0 with GPS module - $65
- MultiWii mega pirate - $49 (same as crius?), GPS $18 (this one looks suitable)
- Transmitter
- Turnigy 9Xr is modular and apparently it has better firmware than the 9X and backlit. The 9X can be modified to have same specs as 9Xr.
- Needs a RF module. FlySky and Orange modules are compatible.
- Receiver - DSM2 (what is maximum distance?) or LRS
- Motors
- Probably need stronger motors than the Turnigy D2811/17 , because the total weight is higher (camera)
- Turnigy D2811/14 brushless outrunner 1100kv, 160W (compared to 102W of the D2811/17), thrust ~650g (x4 = 2600g). Same weight and size as the D2822/17.
- Propellers
- 8060 props are recommended for the D2811/14 motors
- Batteries
- If a stronger motor is chosen a larger battery is needed, e.g. the 5000mAh 3S 20C lipo pack, this weights twice as much as the other one, but the total flight time is theoretically 150% of the smaller one
- Lipo battery calculator
- Camera stabiliser thingies (ah, "gimbal" is the name for it)
- Price range $15-$40, weight 80-200g
- Wires (probably enough of those at home), connectors and stuff
Totals with components of Justa_copter_1 and AnusCopter as basis Weight incl camera: 1160g Excl camera and mount: 904g Total costs: 245 euro Parts-NarCopter.ods

- OrangeRX DSM2 RF module (Turnigy compatible)
Assembly
It already has connectors, so it is a matter of plug and play according to the advertisement. The quad has been modified by others, e.g. other motors, other RX, training wheels, landing gear, one person snapped off one of the arms and made a tri-copter of it (and it still flew).
Forum thread about this copter
The firmware might need customization. In an earlier version the motors kept spinning when on standby, and a minor change might be necessary to connect with the TX.
I want to add landing gear and training wheels (rings around the motors). Update: no need for landing or training gear, the thing crashed into the door so many times without breaking anything. It will be fine.
Flying
18 January 2014: I could borrow the transmitter battery from The JinX. First, the pocketquad had to bind to the transmitter module. I followed the instructions in this quick step by step guide, but had some problems working through the last step; the MultiWii_2_2-gui/MultiWiiConf software. The linux version didn't recognize the device, and I couldn't properly pass on the device to a windows virtual machine. On another system with windows on it it did work. I think the wingui software doesn't scan the ACM dev's on linux. In the end it was "solved" by making a symbolic link to the USB ACM device.
ln -s /dev/ttyACM0 /dev/ttyUSB0
After setting up the transmitter "gear" switch as "aux1" (arm the device), and a quick calibration, it flew.... a little bit. It goes in all directions except the direction I want it to go, but there is movement. It does take off, after which it quickly moves forward and crashes into the door. Next step will be to calibrate the quad better.
19 January 2014: Removed motors, receiver and battery. Recalibrated the quad. Assembled it again. Result: it flies much more stable now. More flying resulted in a broken propeller. Hamish designed a frame with rings around the propellers. Result: it barely lifts off (too heavy)... and a broken frame (the printed one, not the main frame) after flying with it.
23 January 2014: I got very useful tips from phicoh. The quad calibrates on start-up, so you should balance the quad while connecting the battery. Furthermore the expo levels for ELE and AIL were set to 20. These settings helped to make the right stick of the transmitter react slower, which makes the quad less jumpy. Need to have a look at the rudder settings next, since that is not reacting very well.

Dutch law about recreational RC flights
Dutch law recreational flights (Dutch)
In short:
- Officially, flights are not allowed, but an exception is made for recreational flights
- Commercial use of copters is not allowed without permission
- Recreational flights are allowed and you don't have to ask for permission to fly
- Weight should be below 25kg
- The operator must be able to see the copter from the ground
- Using camera's (first person view, FPV) to fly the copter outside of this range is not allowed
- Camera's on the copter are allowed
- Safety
- Do not fly above (groups of) people, buildings, sculptures, railways and highways
- Flying above 30km roads in urban areas and 60km roads outside the city is allowed
- Height: maximum 300m. (450m on a military airfield) Be sure to let someone else check if there is no aircraft nearby if you fly above 150m. The flight should not endanger aviation
- Flying is allowed in 'class G' airspace. In most places, airspace from the ground to 300m is class G. The main exception is the area around airports. Unfortunately, almost all of Amsterdam falls into the CTR of Schiphol. So flying is not allowed. However, some of the model flying clubs managed to get an agreement with air traffic control to fly on some fields that are inside the Schiphol CTR.
- Special care must be taken in areas where military aircraft are allow to fly low. See [1] (Dutch). They fly very fast and low so you have to have somebody to watch out for them.
