I'm sorry, I had not realize I had clutered with all those
test/unfinished file in the in progress directory. I did a bit of
cleaning and only left what I think could be of any use

yes, UOA had manufactured a number of them - Roman, is this still needed ?

this is the latest 4 layer design - still has the old power supply

removed - think they have all disapeared

This is the previous version of my IMU ( picture here :
It is tested and flew a quadrotor
The new version is in the savannah svn in directory paparazzi4/hw/booz
( picture here )
wait for tag 1.0 before fab - should be soon

everthing not under "in_progress directory should be safe to build,
using the last revision when sevral are available

tiny4l_18_1_99.sch/tiny4l_18_1_99.brd were an attempt to design a
4layer tiny2 with eagle. It never got finished, shematics is more or
less complete - I was changing placement to introduce an analog
groundplane when I stopped working on it. Feel welcomed if you want to
finish it.

For brusless controllers, I would suggest using mikrokopter CAD and code
