Hi Fred
I don't have much time in Mono's, but I wasn't thrilled with the noise coming
from
the outrigger wheels and am hoping the 5" pneumatic are quieter. In addition
I didn't like the wheel bearings that are opened with the provided blue wheels.
The gray Colesons purchased also had opened bearings, but I put close fitting
spacers to reasonably cover them.
The bearings on 5" pneumatic Roller Blade wheels are sealed and corrosion
resistant.
All I have on them:
Package these wheels with bearings (Optional) ($7.00 USD):
Twincam Rustproof
They may have some print on them. They are nice bearings with very little
friction.
I installed spacers between them. I'm pretty certain that can take RPMs of
landing downwind on a VERY Hot and Humid day in Nepal!
60mph = 5,280' per minute. Landing in Nepal will be 80mph ground speed or 7,040'
per minute or 84,480" per minute. 5" diameter times Pi = 15,708". 84,480 /
15,708
= 5,378 rpm.
I spun each wheel up with 130psi air from compressor and had quite the gyroscope
going. Vibration was very acceptable. I'm pretty certain bearings will last
tire life. Just as a precaution I would replace bearings at tire and tube
replacement
time.
I'm not quite sure what my wheels are made out of, I didn't scratch them, but
they
are slightly magnetic.:
Powerslide Nordic Road Warrior II 125mm Air Wheel
Perhaps Glass-Fiber Reinforced Plastic? I know JB KWIK Weld is slightly
magnetic,
they may add some steel too?
Happy New Year!
