Re: Europa-List: EZ-TRIM Altitude Hold

Hi all,

I would be interested to know if anyone has one of these units flying.  A 
friend of mine built one for his RV6, but he could never get it to work 
properly.  Ultimately he re designed his unit, and he needed to supplement 
the pressure sensor with a solid state gyro.  He also needed to change the 
software significantly by adding in PID algorithms.  It took him a bout a 
year to shake it all down, but it now works really nicely.
