From: "mark_trickel" 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!

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.
