Nice :thumbsup:

Please do post technical details, pictures and videos of the quad itself, as the audience is mostly interested in that.  Video's shot from the quad are great, but the GOOD stuff is else where :)

It would be good to know the following.

Which software did you use ? 

What were the sources for 3-axis gyro, accelerometer etc ?

i know him ,

im doing Ph.D @ MIT chennai, and he is just passed out from IITM , he also did nice work on quad , but i lost his contact .


PID  nothing but a closed loop system

which has inner loop and outerloop

there are two modes one is  acromode and the other is hover mode

in the acromode  i use gyros alone .. no need of accelerometer it just get the feedback from the rate gyro and make correction @ that instant

in hovermode i use both gyro and accelerometer to calculate the angle to which the quad is disturbed from the horizon , so  in  hover mode we can do  hands free hover ,

In acromode we can do looping , fast yaw , spin  ... but we cannot do the same on hover


acro is like flying a Flybar less T-REX 700 SE   with 30% nitro ,max swash adjustment (she will be wild in the air ), hover is like BIG LAMA damn lazy in the air
