Gary: Thanks. You don't know where the rigid foam came from do you?

The wheels for my 269A were aluminum and the tires were inflated to 70psi.
The aluminum wheels meant that I could take them along if needed and if
the tires were kept at approximately 70 it was an easy push (on a level
hard surface). An acquaintance of mine had similar tires for his 500
filled with some sort of rigid foam (for tractor tires, I believe). This
gave a airless tire that was about as stiff as the one with 70psi.

By God Kevin your idea may not be the best, but it is certainly the first
time I've heard that one. One problem tho I have to carry those wheels
by hand and at my advancing age, it may exceed my capacity. Would the
wheels weigh more than a 6 pack?

I recently tried a pair of Marathon flat free wheelbarrow tires to
replace
my pneumatic tires that had developed the habit of slowly leaking out
the
air.
@#$%^ The rolling resistance was so great I couldn't move the helicopter
by
myself. In fact even with my wife's help it was very hard to get the
helicopter moved on concrete with the flat free tires. Looking at the
contact patch, there was approximately a 3" long contact area.
Replacing
the flat free with the pneumatics, I was again able to relatively easily
move the helicopter. Weight of the helicopter was slightly less than
the
reported capacity of the flat free tires.
Any suggestions?


Pneumatics filled with concrete.
