Do you have the 'warts' over the static holes in the fuselage?
~10 kts low is a typical error for RV's without the warts.
I assume you mean the
typical Van's pop rivet static ports? I used that on the -8, and it wasn't
right either. On the -3, there are real static ports on both sides, hold
the warts. They were already installed when I got the project.
A quick check to see if it's the static error problem is to
set your altimeter to your field elevation & then take off & fly a
full bore high speed pass at low level (near 20' agl) down the
runway.
I'll give that a try
when I get serious about finding the problem, however, the TAS reading on
the EM-2 seems correct, and it uses the same pitot static system as the
ASI. I probably just need to buy better instruments. My VSI has
become sticky, and I almost can't pay attention to it anymore.
Thanks,
Rusty
