There are two pins used for the last two motors of the octa. These last two pins are not the 8 regular servo out pins. They are PB5 for channel 10 and PE3 for channel 11
The Wiki Diagrams should help you locate the motor positions and the Pin names are screen printed on the base of the APM board.
Thanks for the quick reply, then I know it can be done with Octocopter. I will order all the parts I need for this now, it will probably take a few weeks before I have everything by mail. I appreciate that you can help me if necessary. I will come back to this later.
Very good that it's made for 8 engines, it was awesome, thank you :)
Would be nice if you could send me a list of what components I need to order, such as motors,batteries, frame.
No problem, what I've got for my octo setup
Droidworx AD8 HL 360 Airframe ( I am in the process of designing and making my own carbon fiber frames at much more affordable costs if you are keen)
AV200 pro 360 camera mount
Ardupilot Mega+IMU kit x 2 (one for camera mount stabilization)
8 x 350w brushless motors (these are the Mikrokopter ones, MK3638) but any would work fine
8 x 25A(30Amax) ESC for motors
Custom made pdb using cables soldered to give each motor power
a few 5000mah 4S lipos
JR DSX9 radio + receiver
(i dont use GPS on the octo as it not needed at all for us)
signal cables from esc goes to 1,2,3,4,7,8, and then the pins, PB5 (10) and PE2 (11)
code you need to replace is very easy using Arduiono software in the APM_Config.h file replace
#define FRAME_CONFIG QUAD_FRAME with #define FRAME_CONFIG OCTA_FRAME
Build, setup your board, calibrate radio (with no props!) and your set. No need to mess with any settings, they all work 100%
Hope this helps,
This was a great help. What will the price be for the frame you build and how long will it take to finish it. Have you picture of that. Do you use ardupilot to control the camera mont, is it created software for that use.
Duran DeV, you mean PE3 not PE2 ;-)
