Hi , I'm  HeiST
ST800-Scarf
   ( High and ST800)

Okay , after weeks of reading , looking at prices , weighing pro's and cons I decided to go for the large HEXACopter BumbleBee ST800 from HobbyLord

What will follow is YABL (Yet another build log) , and as of this date there is NOTHING on the net resembling a build log of this copter ...( 16 August 2013 )

Please note , My native language is Afrikaans , like in South Africa , so tense and spelling mistakes will be happening ...! or is that ...will happen ? ;-)  nou ja lekker ..

HEXACopter  Specs

Wheelbase:820mm ( Actual measured Motor End to Motor End : 870 mm )
Height:440m

Empty Frame Weight:950g

Below is from the Suppliers... and yes Chinglish ...

1.The machine mainly consists of carbon fiber composite materials, matching joints of aluminium alloy to ensure the strength of body as well as to effectively reduce the weight.
2. The six arms are with 18mm carbon fiber tubes and enhanced motor mount.
3. The connections of landing gear are formed with 14mm carbon fiber tube,which is composed with metal and carbon fiber,to be assembled and repaired easily.
4. Supporting tubes are made from 12mm carbon fiber tube, the span between tubes is 155mm, it accommodates with mainstream camera gimbal in the market.
5.There are two extended boards in front and rear of the fuselage,it is convenient for the installation of GPS, receivers and other equipments.
6.Battery frame is fixed by metal connectors,the canter of gravity of the aircraft can be adjusted by slidding the battery frame back and forth.

The flight controller for this copter will be APM 2.5 ArduCopter, a fully-autonomous multicopter and heli UAV (Unmanned aerial vehicle) system. ArduCopter is an easy to set up and easy to fly platform for multirotors and helicopters. ItsAPM Copter at SCARF features go far beyond the basic manual control RC multicopters on the market today. Unlike RC-only multicopters, ArduCopter is complete UAV solution, offering both remote control and autonomous flight, including waypoints, mission planning and telemetry displayed on a powerful ground station. .
