Dear Friends,
we doing fly test of HexaCoax developed by Daniele A. based on MP32+ VRIMU. The video is the first flight test . We need to finisht the work on PID.
Ciao a tutti,
ieri abbiamo collaudato e fatto volare l'hexa coax di Daniele, una bella realizzazione in aluminio . Il video e' del primo volo e Daniele stava prenderndo familiarita' con il mezzo.
Di solito pilota riproduzioni aeree , ma si e' trovato subito a suoi agio con il suo nuvo drone , bisogna ancora lavorare sui PID , specialmente sullo YAW ancora un po' molle.
This is the configuration of HexaCoax.
I componenti sono :
Firmware : Arducopter32 NG
Scheda CPU : Multipilot32
Scheda IMU : VRIMU
Regolatori Motorius 30 A
Motori Motorius 2217
The source code , lib and ide snapshot is available here :
Lo snapshot del codice utilizzato e' questo : http://code.google.com/p/multipilot32/downloads/detail?name=vrobotix-ide-0.0.4%20mixer%20hexacoax.rar&can=2&q=#makechanges

Hi Randy,
the big advantages is that it is very stable if you broke a propeller ...in normal quad if you broke one propeller you crash in a hexa radial if you broke is possible that you lost a controlo of your hexa .
With a Coax configuration you can lose until 2 propeller and continue to fly. I tested the hexa radial and hexa coax configuration and i saw this results.
I'm working on a heavy lift hexa coax ... yesterday i fly it. I'm preparing a video. The ACopter 32 Heavy lift generation is begin ;)
Hi Roberto,
Looks like it's getting close.
So what's the advantage of a hexa coaxial? I guess one thing is that it's shaped like a tri-copter but it doesn't need a servo to control yaw.
...but actually I never really understood what is good about having an engine above and below on each arm (i.e. coaxial). There's a lot of disturbance on the bottom prop so I believe it's not as efficient (and I know it needs to spin at a different speed from the top one - faster i think).
