General
Started half July 2007, MosaKopter was built in Maastricht-NL (hence: Mosa) using general MikroKopter-rules.
It was the first time for the pilot soldering SMD-components.
Finally after 2 months investing several hours, MosaKopter V1 had its succesfull maidenflight in the first week of september 2007. Here is a picture of the first MosaKopter:
This model served very well during 1,5 years and I had many entertaining flights. Until the unfortunate crash end of January 2009 due to a pilot error. From May 2009 onwards a new model was launched, using carbon fiber rods and a bigger motor<>motor distance of 54cm:
Hardware MosaKopter V2
FlightController: original FlightCtrl v1.0 (green PCB) with AVR Atmel ATMEGA644 @20MHz
Default sensors: 3x Murata Gyros ENBC-03JA, 3-axis ACC sensor LIS3L02AS4
Extra sensors: Motorola height sensor MPX4115 and MK3Mag (magnetic orientation sensor)
Optional Bluetooth module (for in-field programming): F2M03GXA
Speedcontrollers: 4x BrushlessCtrl using standard 5A MOSFETs (10A peak)
Motors: Robbe ROXXY2824-34
Receiver: AcT Rx3Multi
Sender: Graupner MX12 (modell-type: plane, mode:2)
Props: EPP1045 (10" diameter with a pitch of 4,5") held down with Harald's propholders (M3 shaft)
Frame: 12mm carbon fiber rods with a 54cm motor2motor distance. The rods are held down with 2 homemade Center-Plates and extra glue in the joints.
Battery = LiPo 3s (11.1V) 2200 mAh / 30C (175 gr)
Total ready-to-fly weight = 720 grams (including above battery)
Flight-time = between 12 and 15 minutes, depending on the flight-style and load.
Hovering current = ~ 8 Amps.
Settings
I am currently flying these versions: FlightCtrl v0.80 / BrushlessCtrl v0.41 / NaviCtrl 0.20 / MK3Mag v0.23
1: "Normal without GPS & HH (my favourite for manual fun flying)
2: "Normal" with GPS & Heighthold
3: "Beginner" with GPS & Height-Hold and Orientation-Hold (my favourite for taking pictures... stable, and slow on yaw and nick/roll)
4: "Beginner" without GPS & HH
- 5: not in use

The next picture was made with MosaKopter V1 carrying a Nokia N95 onboard using sequence mode with 10 sec interval:
Here is an airshot from june-2008. Also made with a Nokia N95 onboard MosaKopter V1:
As a comparison, same picture but this time shot in May 2009 with a Casio Exilim EX-S600 onboard MosaKopter V2:
