I finally got all four motor controllers built. I wrote software that
correctly varies the speed of the motors (mixes) as a function of control
stick movement. I tried to fly it while it hung from a string from the
ceiling - interesting. Though it was very unstable in pitch and roll - it
was surprising docile in the yaw axis! I mounted the battery about 12 inches
below the motors just to see if I could fly it with out gyros - yes I could
but only for a second or two. The real answer is of course to incorporate
what the gyros have to offer. I already have the amp designed so it is just
a matter hooking it up and adding to the software. (Of course there is the
matter of the two gyro chips that I blew up - any one have two spares they
want to send me?)
I hope to get my one remaining gyro hooked up and debugged next week.
Thanks for the kind comments on this project.

I use Murata gyro chips in an OEM application, and have to buy "A" and
"B" chips in minimum quantities of 100 each. I could spare a
couple. Note their outputs are angular velocity, and their weight is 1
gram each.

send you some money for postage /handling. ( Graduate students are cheap
but still have some dignity).
I am not real familiar with the murata but I believe that it has similar
output as does the tokin. anyway at this stage everything is adjustable
I would like all three to be the same so I will buy a third one from you if
that is OK
Tell me where to send some money. Thanks
this is the gyrostar "enc" variety - right ? I am unfamiliar with the "A"
and "B" designation.
thanks

I too like Richard am working on a similar project. If you could see your
way to selling me a couple of the Murata chips, I would be most
appreciative.
Thanks in advance?
