    currently, I don‘t have a good gps, only got 10 meter accuracy. the
rotorcraft hover in horizontal about 5 meter.  I replace the hove PID with
other example crafts. It seems no difference.
    So I don't know the bad performance of hover is caused by bad gps or bad

    My question is how to verify gps good or poor ? 10 meter is bad of
course. so what about 5 meter? 4 meter ? or 2 meter?
   another question how to tuning PID of hover. I feel it different with ATT
PID. I have no idea of hover tuning? So the only way is to replace with
other example PID.

   the following is my PID used in HOVER

   <define name="PGAIN" value="50"/>  
    <define name="DGAIN" value="100"/> 
    <define name="AGAIN" value="100"/>  
    <define name="IGAIN" value="20"/>  

the PID in comment is the PID I collect in other airframes

Thank you
