This is a picture of my Challenger 1. I completed it in the fall of
99 and flew it about 6 times before the snow came. Too busy to
put skis on it last winter. This in a 1998 kit. It
is the 3rd plane I have built before it. In
1994-1996, a Fisher Flying Products Dakota Hawk, in 1997-8 an RV 6A.
Sold the Vans and still have the Dakota Hawk --- guess I like
slow flying best. I've been flying since 1956 and
was a CFI active for about 17 yrs. Still CFI but not
active. I have my own 1850 grass strip in Rural Hudson, WI. but am moving
to a new home a few miles from here. I have a hanger now in
New Richmond WI. Better deal-- owning your own strip is a lot of work to
keep up unless you fly a lot. You're working on it as much as your flying.
Toms tail brace mod.
This is a picture of tail cable braces added to both sides of my
Challenger 1. This fully stopped the tail vibration. Prior to
this I had put all AN bolts into the tail system (no
clips) Put in 4 more motor mounts, balanced the prop.
Nothing else worked. And now I know why because not of
these will stop a tail vibration because they are not attacking the cause.
I mentioned that while trouble shooting I found that the
vibration would go away every time that I stepped on the
rudder enough to align the rudder with the vertical
stabilizer. This was my clue. My plane had 6 hours on it when
I first noticed the vibration--- I really think it was there all along.
