  1. Quadcopter Workshop Comet ’14 IIT BHU

  2. Scope of the Workshop • To familiarize with multirotor technology by building, testing and troubleshooting a quadcopterand edify for future upgrades.

  3. Scope of the Workshop • Tech you more than soldering in 2 days and inspiring you to push the envelop. Because if you do this for interest and hobby not just for credit marks, sky is the limit. As I say this, I am forgetting the fact that there are foot prints on the moon and tire tracks on the mars.

  4. Introduction to Aerial vehicles • Flight Characteristics an Airplane • Orientation and No. of dimensions • Pitch-Roll-Yaw

  5. Components of Plane

  6. Pitching Moment

  7. Rolling Moment

  8. Yawing Moment
