I used a section of an 18x2 inch BMX bicycle foam inner on my Std Cirrus
tailwheel for best part of 5 years. Never had any problems, it did
eventually start disintegrating - but it's a lot better than the
constant punctures from the thorns in the Free State. The main wheel has
a much thicker, harder outer and is not as susceptible to puncture.

Have the same installed in my Kestrel - which has a very heavy tail. No
problems so far - two years and counting. With my fat lump in the front
the little aft CG movement is welcome.

One suggestion, it is a good idea to make a scarf joint rather than a
butt join. On the Cirrus the sidewall scuffed a little and I flattened
the sides of the inner with a surform rasp.

About 5 years ago I installed one of these into my tail dolly
pneumatic wheel (200 x 50). After seeing no problems I installed the
same into the tail wheel of my Ventus C (same size wheel).

No problems once installed, though the 20" x 2" model I used (20B7)
was about the same size as the fully inflated pneumatic tube, which
made installation of the wheel shims a challenge in the confined space
of the tail wheel well.

The actual rubber tube from No-Mor Flats varied between 1.65" and
1.75" in diameter.

Side note, the added weight was less than 0.5 lbs (1.735 lbs to 2.220
lbs), resulting in negligible CG shift in my configuration.

Has anyone tried using the "Bell No-Mor Flats" foam rubber material in a
tail wheel tire as a safety backup. It looks like the 1.75" diameter
cut to the correct length might be a good safety backup if the tail
wheel tire gets punctured.
