One of the things I did was to install a fuel valve from a Cessna 210
which is a double valve to allow excess fuel flow to be returned to the tank you
are feeding from. Works great on the T-210, however, in this application
there is a need for a small accumulator as the engine quits no matter how fast
you switch tanks! So for now I switch tanks at idle
power.
Still
have that vibration. It seems to have something to do with power as I
can dive at all speeds up to 200mph indicated and don't have it. Under
power it definitely increases in intensity in a skid.
The CCI mount
has pretty stiff dampeners, and I bet this is just some sort of
resonant vibration in the airframe. RV-8's are fairly well known for this
with a Lycoming, and you can scare yourself by just moving your feet to
different spots on the floor. It's amazing how you can change the
vibration level by just varying the pressure in certain spots on the
floor.
Congratulations on the RV-8. Look
forward to a picture of two. May even pop down to see it sometime
when you are going to be at the airport.
Thanks, but the picture
or two ain't much to look at. You can see a few pics and the
first takeoff clip at- http://www.radrotary.com
Bob (the guy
who flew up there with me) has already mentioned wanting to fly back up
when I get my -8 out of it's experimental area. You've got a
really nice area to fly in, and I'm sure the airport will make
Mrs. Garmin worry (terrain, terrain, pull up. pull
up <g>). I somehow managed (mercifully) to only get a 25
hour test period, so it won't be long.
Cheers,
Rusty
