Hi Marco

The RCX is slung underneath the "glider" (actually a 2 meter delta stunt • kite).  It has
one micromotor plugged into OUT_B (i.e., the micromotor contacts are fitted • directly onto
the OUT_B contacts so the center of the motor's rotation is vertically • upwards).  A cam is
fitted on top of the mocromotor with 2-stud axle -- the far end of the cam is • attached to
bridle lines which go to the left and right spars of the delta.

I don't directly control the RCX, it is programmed to to stay straight for one • second, and
then shift the cam slightly to the left -- this shifts the wieght of the RCX • relative to
the center of gravity of the kite,  thus putting the kite into a banking • spiral.  The RCX
also beeps every half second so that I have a way of calculating the flight • time.  If you
want more info, I can post a dat of the RCX to one of the CAD sections.

Cheers

Hi Jonathan

I am a very curious man and so ... here are some question for you :)

Are you sure the micromotor has enough power to move the rcx while flying?

Why you want the kite to enter a spiral dive after just one second flight?

Why do not try instead to use the rcx to try to keep the kite in a straight
flight ?

Bye

Marco
