Tailwheel For GROB Twin Astir

[Mike J.]

Over the years we've managed to "deflate" the tailwheel on our club's Twin Astir due to rough landings, rocks, cactus, whatever. It has always been a pain to remove and replace the tire/tube and often the 90-degree valve stem on the tube we buy is a bit long and hits the fiberglass tailwheel fairing..

Anyone out there have a solution/idea/suggestion on a replacemnet non-pneumatic tire that would do the job?

A 45-degree valve stem fixed with a locking wire to the rim (drill a small
hole) will halve the amount of flats. Stops the valve stem from being
ripped off the tube.

Ditto. I will add that Tim at W&W has the tube you need, page 33 on
his website. Desser does not carry it IIRC.
