progress report on roswell clone
http://www.inetport.com/~davisele/roswell.html
I bought the commercial version because It was cheaper to buy the whole
thing rather than buy individual parts. Kinda fun to fly - but forget it if
there any wind at all !!
I will install my computer on the draganflyer mechanics though I don't even
have any gyros hooked up. I am anxious to see just how much they help (I
might be good enough to fly it with out any gyros)
I have also been toying with the idea of using one rate gyro on the yaw axis
and a regular accelerometer for the fore/aft and one for the left/right.
Based on what I saw during my test flights - that may be the way to make
the platform really stable.
maybe some real progress next week ;-)
My friend is independently working on a flyer also. I may adopt his name of
BX-Flyer.

draganflyer. It flew just fine, I hardly noticed the extra payload. Since my
computer weighs about the same as the one that came with the draganflier . .
I am one step closer to a flying robot version of the roswell clone.

Hi,i am new in this group and happen to see your posting.
I made a draganfly myself and solved the gyro problem with a very easy
solution:
The idea was to take 4 liquid-metal switches and mount them at the
far ends of the arms,with an inclination of about 2 degrees.
So when the arm drops below zero degrees the switch makes contact.
Now with little electronics a circuit checks for input of the
receiver to see if the movement is caused by the operator of the
transmitter.
If yes,no correction is made.If no,then the power of the motor will
be increased in steps until the switch breaks the contact.
This is been done on all 4 arms ,so onces it is in the air i dont
have to make any corrections at all.
This is a low cost solution.
If anyone is interested i will post the plans and schematics in the
file section.
Anyway i am interested in sites or persons that have been doing some
experiments or have build one themselves,to exchange information.
Keep up the good work.
Probe.
