Quadrino Nano with VTail 4/5

[davide]

Hallo guys,

first of all thanks a lot for the answered questions about Quadrino Nano.
They helped me a lot to understand better and better how this wonderful board works.

Since I want to program my quadrino Nano for my VTail 500, there are some options which are not so easy to set. Most of the default options are related to more conventional copters, but I have really hard time trying to configuring some options like the pitch roll aspect of the VTail:

Which is the right value,I should type ? How do I find the right value?

I thought maybe can be helpful to share my experience with all other users so I opened this thread Questions about the VTail copter configuration.

Regards.
Davide

The “Copter” page will get a major Upgrade today or tomorrow. It will be easier to understand and use.
Also the “PID” generated from that page will be loaded to the board to make it easier again.

Here is a quick view of the new page:

It’s important to understand that the values for “Physical Characteristics” changed in that page are there only to generate a starting PID value.
This should make your copter better tuned than using default values from MultiWii.

For a VTail configuration, you don’t have to change the Aspect Ratio of the frame. Just leave that default.
To setup a VTail just select the “VTAIL4” as the copter type and in the “Options / Flight” page there is a dropdown menu with “Custom Mix” and select “KipKool” in there.

Hi all,
that’s nice to know!

Indeed I found some informations which makes a little bit harder for me to understand.

I found the following setup for a VTail configuration in this forum:

[code]//New Kipkool mixing for DiaLFonZo/Bledi VTail’s
//In config.h you must define that line in order to get the new mixing and rotations
//#define MY_PRIVATE_MIXING “NewVTail.h”
//Edited by Eric Nantel - DiaLFonZo - 21/01/2014

// D3----------D10 (Front)
// –
// –
// D9----D11 (Tail)

#define VTAILANGLE 40 // default angle for Dialfonzo VTAIL400/500. Change it for other config if fneeded.
#define VTAILTHRUST sin(VTAILANGLE)

#define STAB_MIX(X,Y,Z) rcData[AUX2] + axisPID[ROLL]*X + YAW_DIRECTION * axisPID[YAW]*Z
motor[0] = PIDMIX(+0,+1, +1); //REAR_R CCW
motor[1] = PIDMIX(-1, -1, -VTAILTHRUST); //FRONT_R CW
motor[2] = PIDMIX(+0,+1, -1); //REAR_L CW
motor[3] = PIDMIX(+1, -1, +VTAILTHRUST); //FRONT_L CCW

[/code]

At a glance nothing is new.
But: the motors name is different compared to the official documentation of quadrino Nano. See the following

So maybe is a problem of a not updated pdf but it would be nice to know which are the correct wires to connect…it helps to understand how things works and save a VTail 4/5 to get destroyed :mrgreen: :mrgreen: :mrgreen:

Side question: I look in my pc for the folder where Quadrino Nano save my configurations data. I couldn’t find it. Where is it supposed the installation folder to be? I know, one can call the config.h from quadrino nano itself but in there I cannot find the motor definitions and allocations.

Regards!!!

When using MultiWii, there are different Pin-Out for boards that use an ATmega2560 and 328p.
The pinout shown in the “NewVtail.h” as you describe here is for an ATmega 328p and the Quadrino Nano use a 2560.

Use the pinout shown in the Quadrino Nano QuickStart guide:
