Jos & all,
A have a friend who built the EZ Trim for his RV6. After many months of
trying to get it stabilized he gave up. He ultimately scraped all of the
code, reworked the PID algorithm and added a solid state gyro in as an
outer control loop. It took him nearly a year of tuning the PID factors in
the altitude sensor and gyro to get it to work properly.
It now works really well and I am fooling around with the code at the
moment. Quite frankly I am expecting 6 months of experimenting / tuning to
make it work in my Europa. I am more than willing to share once I have it
figured out, but it is not easily transportable because it is based on a PIC
16F876 (not a STAMP) and you need the ability to be able to burn your own
microprocessors.
