When I order my frames, there where 2 different camera mounts. One is the simple fixed plate, which is easy to see how it is intended to be attached. The 2nd mount consists of 2 plates, and 4 small disks. Do you have a picture of how you intend this one to be attached? Might be obvious if I had the GoPro on hand now, but it's not here yet.

Thanks!

Here it is. I'm betting on some kind of anti vibration design.

By the way, your CNC work is top notch, great job!

Thanks but the kit you have was cut by Luis (www.myrcbuild.com)
I will try to get you a 3d file showing how it work but you need some kind of dampers that's why the round washer are for.

It's a simple solution that Luis came with.

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
    int vtail4Thrust;
    vtail4Thrust = (int)(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.
Ok i think that would work..
I have took a bit of time to answer since i want to be sure it look good.
Thanks a lot for doing that.

Now we need to put that on the test before request it to be included in Multiwii 2.1

Anyone... ?? (still not have my bird ready...)

Yes we can make you such GoPro mount..

There was a mistake in my code below. I've edited the post and links with correct patch & files.

I've just tested all different config in the field, everthing works correctly here.
This could be pushed in svn now.
