check your props too, in video 19 i noticed the right mount vibrating a lot. You'll loose alot of power running an imbalanced system.

yes your ri8.. both the throttles have been flushed away from the mounting at different time. so remounted them again correctly.

what do u suggest me to do now to get success...

Jyo, How much time do yo have left to complete this project. Back in the beginning of December you had told me that you only had 2 or 3 months for this project. Do you still have a deadline?

@foam and tape

should we use counter rotating propeller or CX blades.

Better use counter-rotating propellers. You can just about manage with equal handed propellers, but they will cause a lot of trouble in fine-tuning and cause some nasty handling effects.

I recommend GWS gyros or similar since I don't think you have enough time left to learn MultiWii.

I think your multiwii will have to have an accelerometer if you use one. If you want MultiWii then here is some code for you. It's for use with a ProMini arduino. I'm not sure which arduino pin to use for the motors but it's either digital 3, 10, 11, or 9. Plug your ESC signal wire into one of these until it works. This code has not been tested so you will have to do that.



At the top of the file you can change the delay of when hover or forward flight controls start here...

Code:
 int userHoverDelay =350;                  //QTR   350 is about three seconds.   Is is the amount of time to waite until hover controls work.
 int userForwardFlightDelay =350;          //QTR   350 is about three seconds.   Is is the amount of time to waite until forward fligt controls work.



You can change the motor and servo commands here... (Change a sign from + to - if you need to reverse the servo direction.
Code:
///////////////////////////QTR Motor and Servo commands./////////////////////////////
void hover()
     {
      motor[0] = rcCommand[THROTTLE] -axisPID[ROLL];                                               //Left  Motor       Arduino Pin- 3, 10, 11, 9.
      motor[1] = rcCommand[THROTTLE] -axisPID[ROLL];                                               //Right Motor       Arduino Pin- 3, 10, 11, 9.
       servo[1] = constrain(1500 +axisPID[PITCH] +axisPID[YAW], 1020, 2000);                   //Left  Aileron     Arduino Pin- A0
       servo[2] = constrain(1500 +axisPID[PITCH] -axisPID[YAW], 1020, 2000);                   //Right Aileron     Arduino Pin- A1
       servo[3] = constrain(1500 +rcCommand[PITCH],                 1020, 2000);                   //Back  Elevator    Arduino Pin- A2
     }

void forwardFlight()
     {
      motor[0] = rcCommand[THROTTLE] +rcCommand[YAW];                                              //Left  Motor       Arduino Pin- 3, 10, 11, 9.                      
      motor[1] = rcCommand[THROTTLE] +rcCommand[YAW];                                              //Right Motor       Arduino Pin- 3, 10, 11, 9.   
       servo[1] = constrain(1500 +rcCommand[ROLL],    1020, 2000);                                 //Left  Aileron     Arduino Pin- A0
       servo[2] = constrain(1500 -rcCommand[ROLL],    1020, 2000);                                 //Right Aileron     Arduino Pin- A1
       servo[3] = constrain(1500 +rcCommand[PITCH]+1, 1020, 2000);                                 //Back  Elevator    Arduino Pin- A2             (+1 for trim.)
     }

thanks for your concern.

wii how much time will it take to shipping in hobby king, last time it took around 15 days i hope so.

now i m thinking of this

what do u say.
I say bad.

It doesn't use the 328p chip so we don't know if the 1.7 code I posted is compatible.

Also none of these boards have the pins labeled. HobbyKing sells a 5v Nano that has all the pins clearly labeled. They also sell the motion plus gyro and nunchuck accel. They probably also sell a USB to miniUSB cable. I can't help with any of the "all in one" boards.

u said multi wii in ur previous post.

tell me clearly which is best and provide any web link of it so that i am not confused regarding their models.

i did not buy it, just borrowed from one of my frd.

i found vtol option in that programming option.

program was over and need to be tested
Jyo,

Do you still have this KK board available for your project?

Sorry, meant Arduino Nano...

Arduino Nano board. http://hobbyking.com/hobbyking/store...ler_Board.html
Wii Nunchuk accelerometer. http://hobbyking.com/hobbyking/store...i_Nunchuk.html
Wii Motion Plus gyros. http://hobbyking.com/hobbyking/store...tion_Plus.html


...or better yet go with what LeadFeather says. I see that you have a dead line of 10 days left. Not enough time to build a MultiWii.
