Hi,
The Quadrocopter speed of rate sensors signals has to be larger than
accelerator signals.
If backstepping is used , a 10ms rate work for the point of
stabilization.
Since the accelerator signals are only used for bias correction a
rate of 20 to 50ms is working well.
The point is that the estimation of the angle can be done much slower
than the basic stabilization without any problems.

Hi Christophe,
I'm still buying the BOM. Slow process. I have the LPC and other
large parts.
I'm curious. How did the flying with PPZIMU Go? Last I remember
you said you were test flying last week I believe. I'm wondering what I
can expect.

The YAI imu is software compatible with the
Booz-imu (just need a different calibration). Please note that while
the gyro's are relatively easy to solder, the accelerometer and
magnetometer are not that simple with there pads not sticking out the
sides.
The aspirin-imu at this moment only has a simple 100Hz driver
for the LPC processor (on booz), good enough for fixedwing (way faster
than thermopiles) but for quadrotors you probably want to improve the
driver first.

Hi
all,
I'm trying to make the paparazzi hardware. I have soldered
the main and the GPS boards. I have soldered the IMU board too but I
think I's going to fail due to the difficulty to solder Gyros and
acceloremeters.
I would like to use another IMU. I'm thinking to buy Aspirin
IMU or to make YAI IMU. Do they work with BOOZ? Has anyone try them?
Thanks in advance
Regards,
Rafael Espino.
