i have designed my own OCTO copter (1meter in diameter) + 3 axis camera gimbal from scratch + hard case for the Ardumega and receiver.
and would like to share with you what i came up with
before i start i would like to note that the materials used are not the best choice, but since there was nothing available in this part of the world and shipping carbon fiber parts is not possible i had to go with aluminum and plexi glass.
i used 2cm * 2cm * 1 mm aluminum square tubes
motors are from DIY drones with 35cm wires 2836/9
each engine has a thrust of 1300g aprox
i'm using Ardumega from DIY Drones as the main controller with magnetometer + sonar
so far it has proven to be the best thing i've ever bought for this hobby. i enjoyed it so much
i bought 8* 25 AMP Turnigy esc's from hobby king.
currently using 11*4.7 props but will go with the 12 later on down the road.
all well balanced
today i had the first flight and it was very good. flying characteristics were great.
can't wait to go out again and carry some more tests and finally put on a camera and have some aerial footage .
Ardu mega will be responsible for the compensation on the roll/pitch axis at the moment. later on i will upgrade it to control all three axis.
here are some pics of the project, feel free to ask me anything, your feedback is important to me. it better be a good one :P
This looks like a great start of a project!
What does that weigh? and how much can it carry?
without the gimbal it is almost 2 kg, with two 6,000 mah batteries and the gimbal flying weight is 4 kg
it can carry a payload of 3 to 4 kg though im going to test the maximum lift capability soon.
i still need to upgrade the props to 12 inch and pitch 4.5 and run it on 4s
a new frame should be built out of the right materials hopefully i can get them soon.
