Al, which radius blocks did you use for your installation?

I am a fan of the radius blocks however these things do nothing to absorb the impact
other than facilitating the flexing of the landing gear. If you use one
of these blocks in the stack you will be narrowing the support area with which
the landing gear has to operate within. We already have cracks and fiber crushing
at the bolts I would not want to aggravate the situation by reducing the
support area.
Attached are two pics from R Reeds site of Harry Herst's TR-4 showing the width
of the surface involved here. You see how wide the Butyl rubber pad is - two
or three time the width of the radius block. I am pretty sure the radius block
were developed for metal airplanes. A radius block could be custom designed
for the TR-4 but it would be much cheaper to add another layer of rubber if you
were that concerned about the gear being able to flex. The other pic shows what
a good wedge should look like.
Speaking of the main gear flexing...the term I use because I never considered aluminum
to be springy - believe me these aluminum gears will flex a hellen. If
you left the boots off, and hit hard enough you'd have black tire marks on the
underside of the wings. Really!
OC - Unfortunately the recess for the landing gear on the TR-1 is too small and
the gear will not fit within the space once it has been canted forward leaving
out the possibility of a radius block....you would be surprised at the number
of builds out there that do not have this vital modification!

Hi Galin,
I'm interested on your W&B data before and after prop change.
Could you please send me the weights and the arms for the loads and for the scales
or the empty weight and arm? Please send it to ( fasilpereira(at)yahoo(dot)com
).
Since you have reported a great improvement on your landing characteristics after
changing the prop, I'll try to make my airplane W&B to match yours.
Best,
Fabricio

Galin,
We haven=99t heard from Bob Anderson, but When I was at that
stage, he suggested using a section of farm machine belting =93
used to power hay blowers, etc which he sent me a small amount. It is
rubber that is reinforced with fibers and is very tough but resilient.
If bob is still on the list, you might check with him.

There's a chart of sizes on Grove web site. Measure your gears dimensions a

Al,
Hey, I will get over it.=C2- I was just looking up the McMaster site when
you replied.=C2- Had to laugh.
As for my plane, it seems to be one step forward and 10 back as of late.=C2
-=C2-I had hoped to get the painting done this year and=C2-did apply
the color coats to the fuselage only to have them bubble and peel off the n
ext day.=C2- I have given up on painting, without proper facilities on th
e field and not being allowed to spray the options are few.=C2- I will go
with an alternate and try the vinyl wrap after stripping and=C2-reapplyi
ng=C2-an epoxy primer.
All work though has had to stop for financial issues.=C2- Starting in Oct
ober of last year through this month I have been fighting foundation and pl
umbing problems that have broke the bank to the tune of over $30k total.=C2
- Insurance does not cover one cent of it so it is all out of pocket.=C2
- I think we have finally found all of the issues and repaired them but i
t has destroyed my yard and my sprinkler system so I will have to fix those
before going into summer.=C2- There is more damage that will just have t
o wait.
I hope to get back to work on the plane by sometime in June but it will rem
ain slow going.=C2- I am really getting=C2-tired of life getting in the
way of my fun.=C2- I am=C2-afraid that I am starting=C2-to waffle be
tween stubborn determination to finish and resignation that I should give u
p and=C2-sell it.=C2- I just can't bring myself to take that big of a b
ath on the project so I guess I will just keep plugging along.

Mark,
I have a TR-1, is the vital modification you speak of in the last paragraph,
The wedge canting the gear forward? If it is, how thick is the wedge?
Thanks,

I am a fan of the radius blocks however these things do nothing to absorb
the impact other than facilitating the flexing of the landing gear. If you
use one of these blocks in the stack you will be narrowing the support area
with which the landing gear has to operate within. We already have cracks
and fiber crushing at the bolts I would not want to aggravate the situation
by reducing the support area.
Attached are two pics from R Reeds site of Harry Herst's TR-4 showing the
width of the surface involved here. You see how wide the Butyl rubber pad is
- two or three time the width of the radius block. I am pretty sure the
radius block were developed for metal airplanes. A radius block could be
custom designed for the TR-4 but it would be much cheaper to add another
layer of rubber if you were that concerned about the gear being able to
flex. The other pic shows what a good wedge should look like.
Speaking of the main gear flexing...the term I use because I never
considered aluminum to be springy - believe me these aluminum gears will
flex a hellen. If you left the boots off, and hit hard enough you'd have
black tire marks on the underside of the wings. Really!
OC - Unfortunately the recess for the landing gear on the TR-1 is too small
and the gear will not fit within the space once it has been canted forward
leaving out the possibility of a radius block....you would be surprised at
the number of builds out there that do not have this vital modification!
