After all the theories about RV-8 landing manners recently, can't help but
put in my two cents worth! My son and I have been flying our -8 for two and a
half yrs. now and feel that we have learned a little about the characteristics
with the CG towards either end of the envelope (ran out of elevator at fwd end,
and sensitive pitch control aft). Solo, we ballast 45 # in the aft bag.
cmpt., and put that ballast in the fwd cmpt. with two aboard (Van was a bit
generous with the CG range, considering a Cessna Citation jet has just about the
same, 8"). By the way, leave the T/W first landings to planes with a tailhooks!
As for directional skittishness, we don't have much slack in the tail chains
(also replaced Van's t/w springs with a pair just a little softer), and made a
new steering yoke which is about 1/4" wider on each side to slow things down.
We also had a tail spring that was badly drilled at the factory and would not
keep the t/w steering axis vertical (had 6-7 degrees of rotational slop),
installed an AN taper pin instead of the retainer bolt. If that axis is not
vertical, the t/w will not track well on initial touchdown. RV-8 brake pedals also
will apply some brake pressure with any significant foot pressure (yeah, heels
on the floor), whether you want braking or not. We put a small extension on
the bottom of the pedals, extending down and to the rear. We now consider the
landings now to be on par with the Citabria we had for years.
My background, Navy 6 yrs, big iron 34 yrs, 900 hrs t/w last 7 yrs, 200 RV-8

Sam - thanks for the info! You reminded me to do something about
the pedals. It had somehow dropped off my list of things to do.
