Octocopter, parts list

Posted by simon on June 9, 2011 at 11:33pm

Hi

I'm looking to build an octocopter and was hoping some of you could have a look at my parts list and give me some advice, whats good whats not, anything I may have forgotten...

 

ArduPilot Mega kit

HMC5843 - Triple Axis Magnetometer

RCTimer P-ESC 40A

BC2836-11 Motors

Graupner Elektro Prop 11"x5

Zippy Flightmax 5000mAh, maybe the 8000mAh ones

Turnigy MAX80W battery charger

Xbee telemetry from sparkfun

 

The Frame I can make myself from tube I already have.

 

Any input would be great.

 

Thanks

    anyone got an idea what is the difference between RCTimer's BC2836-9 motor (with 40cm wire) and Jdrones motor ?

    they are totally identical.

    on the former jdrones motors there was a label A2836. so what's the difference between BC and A ?

     

    Jani, could you please expand on this ?

    do you test jDrones motors for correct balance ? load tests ?

     

    I've had some issues with RCTIMER BC2836:

    one had the motor fixing screws holes totally off - different place than others

    one propeller spinner was really unbalanced - totally offside

    and one came shorted at the lever of the shrink at the motor input wires - solved it, but still...

    Was wondering if u were planning to have Rc receiver in loop ? Any thoughts about power distribution board ?

    I have those motors.  The highest current draw recorded on the test bench was ~20 amps.  Tested thrust both at 3s and 4s with a range of props from 10" to 12*8.  RC Timer is offering that or a similar motor with long wires.  Also have the RC Timer programmable 40 amp ESC, it actually ran nice and cool.  Tried Turnigy Plush 25 Amp, it ran fine but a lot warmer.

    I cant seem to open the RC timer page for the motors, but I think that you dont need such a big ESC, I think most people use a 25A/30A esc, But as I said I cant open RCtimer to have a look at the motor so I could be wrong.  BUt otherwise seems good, also make sure to buy some connectors if you dont have any, aswell as some wire for power distribution.
