| Subject: | Re: Trim setting question |
Pete,
I have my Europa in Kenya, Classic monowheel, my base strip is at 6000 a.s.l, usually
25-30C, so hot and high, and I have a Rotax 912UL and fixed pitch warp
drive. So my conditions are probably different from most. I trim the other way
to the way most have discussed here, ie on takeoff I trim nose up this actually
has the bar in the indicator down below the centre, thats the way I have
it configured. On takeoff this trim arrangement pins the tailwheel down, and
I keep it that way till 40knots, the minimum required to have tail-up rudder
authority. Then, at 40,knots, it requires a gentle but positive push forward
to raise the tail. With about 50knots indicated just ease back on the stick,
she comes off in ground effect, then forward push to get the speed up. Then with
positive climb out at 70 knots trim forward, ie nose down to maintain this
and away you go. On landing I have the trim more nose down, so that the flare
requires positive back pressure. My own particular way of flying the monowheel,
but maybe this helps.

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!
Ron P.

Indeed they are very quiet, and wear *way* better than the much heavier europa
stockers.
Fwiw,
Cheers,
