Oscar,
I agree--I would get back in the air quicker if I left it as-is, but I think
we all agree, the spacer is wrong. The tail is probably too heavy. It is
not only my tail wheel, but the three large leaf springs. It just looks too
heavy for this light bird. Remember I am installing steerable tail wheel as
well.
Where do I get the William/Ryan W&B data? Sounds good.
Miss you here at 8T8. Please call when you come back so I can visit. Do
you have someone at your hangar? I see a small blue car there. John

John,
When I had a leaf-spring type tailwheel on mine, I only used one leaf,
roughly 1-1/2=9D wide and =C2=BC=9D thick, from a Piper
PA-12 (which used a 3-leaf spring). If you can get away with it, it
will be lighter. Just make sure the spring is stiff enough to keep a
large deflection from damaging the bottom of the rudder or any other
structure on the airplane.
I later changed to a coil spring as designed by Bernard Pietenpol, using
a =9CHomebuilder=99s Special 4=9D Tailwheel=9D
from Aircraft Spruce. Using this lightweight tailwheel and the
coil-spring/ A-Arm assembly I was able to shave about 4 lbs from the
total weight of the tailwheel assembly, from a total of about 9 lbs to
about 5 lbs

Subject: | Re: Tail wheel assembly weight |
John,
Yes, the BHP Coil spring design works well, although it needs some
modification from the original design which was for a tailskid, not a
tailwheel.
The first coil spring tailwheel assembly I made was done per the plans,
with the only difference being to mount a tailwheel rather than the shoe
of a tailskid, and I ened up with the tailwheel aft of the coil spring.
I do have a steerable tailwheel, and what I found was that the steering
loads on this design caused the whole assembly to twist, rather than
simply turning the tailwheel. Here is a picture showing what it looked
like:
I flew this assembly for about 3 hours, then one day while taxiing for
takeoff, and turning into the wind, the whole assembly twisted so much
that it broke. I went home, redesigned it, and made a new one that has
worked well for the last 250 hours. Here=99s a picture showing
the difference:
The first change I made was to do it more like BHP=99s tailskid
and put the wheel directly underneath the coil spring, eliminating part
of the moment causing the twist. The other was to add the stiffener
near the open end of the fork, turning it into a much stiffer A-frame.
Note that this requires using bolts to attach it to the fuselage
fittings, rather than springing clevis pins into the fittings as the BHP
plans show. The only thing I wish I had done differently is that the
angle of the tailwheel kingpin is leaning slightly too far aft, which
can cause the tailwheel to break into full swivel mode a little easier
than I wish. To fix this will require making a whole new assembly and
it isn=99t enough of a bother to be worth that.
Hope this helps,

Yesterday was the First Annual Nor-Cal Truck Pull. With a record crowd,
from as far as Texas and cheers from the horse stables, first time entrant,
Gary Boothe's mighty Corvair powered AirCamper ran flawlessly. With
260 lbs of thrust, it strained against the ropes trying to tame it. Without
actually moving the truck, He was easily the winner!
Upon post-run inspection, it was discovered, that Gary's pilot, Curt put his
weight into the pull. While holding the brakes to prevent the clip-winged
Piet from getting airborne, he pushed his dairy-air too hard into the back
of the seat. Gary now has a Broke Back Piet. With some reinforcement,
posting of pictures, detailed description and sketch-up drawings, he'll be
ready for another run in less time that it takes Kevin to change a broken
spoke.

Ha! What would I do without friends?!
Curt is right. It was all he could do to hold back the screaming mass with heel
brakes. Doing so demonstrated a weak point in a x-member midway behind the pilot
seat...well, that's what such events are for.
Nevertheless, I have decided to put some effort into re-pitching my prop.

Please keep that fish scale so you can measure your thrust again after the

Actually, "industrial fish scales" are used along with other fish
by-products in the manufacture of dog and cat food. "Sportsman fish scales",
on the other hand, have no known use, and are merely periodically rinsed out
of the boat...
