Can't wait for mine to arrive, last I checked, still in Chicago on the 10th. Its got halve the world to travel to get to me.
Why would I change the name of my frame...?

I was just quoting you,

(Hunter-Vtail by DialFonzo & Bledi
Hi All,

I am proud to introduce the Vtail by DiaLFonZo & Bledi.
This is born by an idea of Bledi that he already fly.)


Oops, did I type F&B, should be D&B or B&D Sorry
( One finger typing)
Anyway thks to both of you for a great looking frame.

The idea of the VTail was from Bledi. He contact me to design a frame with that special configuration.
thing I did...!

Thanks again Bledi to have thrust in me

Hey, I wasn't trying to be Not Nice. It's a multi-rotor design. The power system produces thrust. Trust/Thrust, it's funny! (And despite his claim, I've found Dial's English to be pretty good. It's sure a hell of a lot better than my French!)

Yes without Dialfonzo the were no VTAIL. My pleasure is to know that now a lot a people is flying on my concept.
Don't worry about my joke it's just for fun. I have no royalty on my name or on the VTAIL.
So just have fun and call it as you want, hunter vtail, dialfonzo vtail, bledi vtail or bledi & dialfonzo vtail it's the same ... THE MORE IMPORTANT IS THE FUN

No matter if it's Vtail B&D or D&B, mine is on its way!
Can't wait to receive it!

Hi all,

I think the research that Kipkool is doing are great. And like the fact that he try to changes things in Multiwii code that are not 100% right.

The rotation modification look to be a good idea and i would retain that.

But for the Mixing i would keep it like it was cause it decrease the carracteristics of the VTail frame.

Maybe we could create 2 version of the VTail in Multiwii code.. ?

We need to keep the code like it is right now cause all people who already have a VTail frame will need to make Hardware change to be able to fly their frame again after Multiwii 2.1 release.

Give me one day, I think I have the good solution to make everybody happy
Just have to code it.

The idea here:

Adding some VTAIL4 parameters in config.h and dynamicaly generate the correct motor mixer at compile time using preprocessor

/**************************** VTAIL QUAD configuration ****************************/
/* set rear motors angle */
#define VTAIL4ANGLE 40
/* this will compensate yaw/nick/roll in motor mixer to have perfect YAW/NICK/ROLL rotation on one axis at a time.
/* If you have different motor/props configuration DO NOT activate any of the compensation below
/* It's not possible to calculate the perfect motor mixer in this case because of too many motor/props combination*/
#define VTAIL4YAWCOMP
//#define VTAIL4NICKCOMP
//#define VTAIL4ROLLCOMP

Ok it's done. Was quick.

Here is the patch:

http://xmltv.free.fr/multiwii/vtail4patch.diff

and a prepatched version here:

http://xmltv.free.fr/multiwii/MultiW...ailpatched.zip

There's more propoer ways to write this.. But here is the idea, and this should work well. I'm not really a programmer.

What has been modified:

config.h

Code:
 
//#define VTAIL4  //WARNING: motor rotation has changed: Front Left & Rear Right: CCW, Front Right & Rear Left: CW )

 /****************************    VTAIL QUAD configuration ****************************/
  /* set rear motors angle */
  #define VTAIL4ANGLE 40
  /* this  will compensate yaw/nick/roll in motor mixer to have perfect YAW/NICK/ROLL rotation on one axis at a time. 
  /* If you have different motor/props configuration DO NOT activate any of the compensation below
  /* It's not possible to calculate the perfect motor mixer in this case because of too many motor/props combination*/
  #define VTAIL4YAWCOMP
  #define VTAIL4NICKCOMP
  #define VTAIL4ROLLCOMP

Output.pde:

Code:
  /*************** VTAIL4 Mix table *********************************/
  //calculate correct front motors thrust depending of rear motor angle

  #ifdef VTAIL4
    double vtail4Thrust;
    vtail4Thrust = sin(VTAIL4ANGLE);
	#if !defined(VTAIL4YAWCOMP) && !defined(VTAIL4NICKCOMP) && !defined(VTAIL4ROLLCOMP)
		motor[0] = PIDMIX(+0,+1, +1); //REAR_R
		motor[1] = PIDMIX(-1, -1, +0); //FRONT_R
		motor[2] = PIDMIX(+0,+1, -1); //REAR_L
		motor[3] = PIDMIX(+1, -1, -0); //FRONT_L
    #endif
	#if defined(VTAIL4YAWCOMP) && !defined(VTAIL4NICKCOMP) && !defined(VTAIL4ROLLCOMP)
		motor[0] = PIDMIX(+0,+1, +1); //REAR_R
		motor[1] = PIDMIX(-1, -1, -vtail4Thrust); //FRONT_R
		motor[2] = PIDMIX(+0,+1, -1); //REAR_L
		motor[3] = PIDMIX(+1, -1, +vtail4Thrust); //FRONT_L
	#endif
	#if defined(VTAIL4YAWCOMP) && !defined(VTAIL4NICKCOMP) && defined(VTAIL4ROLLCOMP)
	    motor[0] = PIDMIX(+0,+1, +1); //REAR_R
		motor[1] = PIDMIX(-1, -vtail4Thrust, -vtail4Thrust); //FRONT_R
		motor[2] = PIDMIX(+0,+1, -1); //REAR_L
		motor[3] = PIDMIX(+1, -vtail4Thrust, +vtail4Thrust); //FRONT_L
	#endif
	#if defined(VTAIL4YAWCOMP) && defined(VTAIL4NICKCOMP) && !defined(VTAIL4ROLLCOMP)
		motor[0] = PIDMIX(-1,+1, +1); //REAR_R
		motor[1] = PIDMIX(-vtail4Thrust, -1, -vtail4Thrust); //FRONT_R
		motor[2] = PIDMIX(+1,+1, -1); //REAR_L
		motor[3] = PIDMIX(+vtail4Thrust, -1, +vtail4Thrust); //FRONT_L
	#endif
	#if !defined(VTAIL4YAWCOMP) && defined(VTAIL4NICKCOMP) && defined(VTAIL4ROLLCOMP)     
		motor[0] = PIDMIX(-1,+1, +1); //REAR_R
		motor[1] = PIDMIX(-vtail4Thrust, -vtail4Thrust, -0); //FRONT_R
		motor[2] = PIDMIX(+1,+1, -1); //REAR_L
		motor[3] = PIDMIX(+vtail4Thrust, -vtail4Thrust, +0); //FRONT_L
	#endif
	#if defined(VTAIL4YAWCOMP) && defined(VTAIL4NICKCOMP) && defined(VTAIL4ROLLCOMP)
		motor[0] = PIDMIX(-1,+1, +1); //REAR_R
		motor[1] = PIDMIX(-vtail4Thrust, -vtail4Thrust, -vtail4Thrust); //FRONT_R
		motor[2] = PIDMIX(+1,+1, -1); //REAR_L
		motor[3] = PIDMIX(+vtail4Thrust, -vtail4Thrust, +vtail4Thrust); //FRONT_L
	#endif
  #endif
This should be tested , but there's no reason it doesn't work.

Wooho!
Order placed to my rc build.
Red and black. Now how do I get a camera plate for the 500?
