--> RV9-List message posted by: "Vic Jacko" <vicwj@earthlink.net>
Hi, I used the Ellison on a Lyc 0-235 for 200 hours with no problem while using
auto fuel. My only caution is to assure the fuel has no alcohol in it.
Ellison will not state it is OK to use auto fuel but with the before mentioned
cautions there will be no problems.
Hope this helps.
Vic

The better balanced, the better,,, but don't go nuts over it. I hung my
elevators on the HS during construction and noticed that they dropped to
the bottom due to the weight of my servo motor. To counter this, I had to
form and attach an additional lead counterweight. I hear that Vans has
since changed either the amount of lead or the instructions for cutting the
lead, I'm not sure which. I intentionally left slightly more weight than
needed, so that the elevator now trailed slightly high. After final paint,
it falls roughly level. If I needed to remove more lead, I could simply
drill into the weights, but close enough is close enough. She flies like a
dream!

Speaking of precision, what have people found out about:
Accuracy to which the Horizontal Stabilizer Tips should be of fixed
distance from point on firewall - I have it down to 1/16". Is this good
enough?
Accuracy to which the Horizontal Stabilizer should be aligned to level -
I have it down to 0.2 degrees. Is this ok or should I add shims to get it
closer to 0 degrees?
Accuracy to which Right and Left Elevators should be aligned to each
other - I have them down to 0.6 degrees and am worried about potential roll
torque at high speeds?
If anyone has any sage advice here please let me know.

Relative to issues of balabce - I had to add some mass to weights to account
for electric trim motor. I have left them a bit heavy and will drill them
out if and when it is needed. Better to be a little heavy and take material
away than to have to add material later.

will simply set in trail? Van makes clear his concern for flutter in the
performance testing of the manual. Has anyone experienced problems here and
to what degree of detail should we strive for? I recall reading somewhere we
are not trying to balance the system only prevent flutter.??? Also if anyone
has drilled the counter weights to lighten it did you drill a series of
holes along the centerline or just one?

My advice would be to keep building and stop worrying about precision. It
sounds like you're well inside the envelope where the wings stay with the
craft.

Balence each half sep.this way you can get better balence in case you have a trime
servo or more paint on one side then the other.multi.holes along leading edge
of counter weights worked best for me.less on servo side. bolt together after
balenceing very smooth.you are balenceing the surface not the linkage just
like rudder and ailerons.
