Re: [Paparazzi-devel] ROTORCOPTER FOR 500g camera

[Christophe De Wagter]

Dear Rui,

You can use almost any combination of rotors. In paparazzi you just fill in the "motor-control-matrix" to translate the pitch-roll-yaw to the correct motor [e.g. in quad: to roll left motor must increase and right decrease]. There are many examples and there is even a matlab script to allow you to place your motors almost randomly and just measure their location and turn direction. You can even mix in servo's with your motors for instance in tri-copter or quadshot.

The limits are: the I2C bus gets pretty filled at 8 rotors 512Hz commands... so for more than 8 rotors you might need 2 busses or control matrixes in your motors.

I saw this:

With this information I can use paparazzi for an hexacopter configuration, Right? I will just need to change the SUPERVISION section values.


And for a coaxial copter is the same principle too?

Than you, I will have a look.


The paparazzi will work on such platforms?

Is there any disadvantage to use an hexa or octo in a coaxial configuration? Will paparazzi handle it well?

Dear Rudi Costa,
please look for heavy Mikrokopter at mikrokopter.de
I think a hexa or okto will be nesserary.

Hi all,


I would like to build a rotorcopter to carry the new Sony NEX-7 camera. It weight 291g and the lens about 194g.

So it has to be capable to carry 500g-600g of payload (camera and mounting).

Can you help me with configuration ideias? I would like to use Lisa/L for it.


I'm thinking on one of the next configurations:

- Quadcopter
- Tri coaxial copter (6 motors total)
- Hexacopter


Actual code from paparazzi handles with that configurations? Or I will have to program to work with?



Best regards
Rui Costa
