Change the tire to a 700x6. It will solve the tire rubbing the landing gear
frame. I have used the 700x6 size past seven years w/o any problems.

Team,
Prior to first flight I replaced the original tyre supplied by Europa with
a
Tru-trac 8.00 x 6 x 6 ply after several cycles it started to rub against th
e
root end of the L/gear forks progressively getting worse, I made up two spa
cers
ending up with 3mm thick on the right side and 2mm on the left and all was
well.
Having now done just over 100 cycles it is starting to rub again on both si
des,
I'm loath to add more spacers for fear of getting to close or starting to
conflict with the Rudder cables passing through the wheel well. As I see it
I
have two options, replace the Tyre with a narrower one (would that be a 7.0
0 x 6
x 6 ?) or remove the swing arm (with all the work that entails) and get an
engineering shop to reform it, which would allow the removal of the existin
g
spacers and retain the existing tyre. I would appreciate the forums thought
s on
the pro's and cons as regards the narrower tyre etc. I use grass strips,
tyre at approx 20psi.

Hi Bud,
I have an Air Trac 8:00 tyre inflated to 30 PSI, in order to favor prop
clearance. I have tested anything from the factory recommanded 18 PSI to
35 PSI and have not found any significant effect on bouncing, regardless
of runway surface.
After 600 hours flying the monowheel, I bounce it from time to time and
manage to grease it sometimes. Other landings are reasonably good.

If "landing on the point" means that the main wheel is touching first on th
e runway, that is most of your problem.
-
The monowheel tire is located ahead of the center of gravity and as soon as
the tire touches the runway the tail will go down until the tailwheel-re
aches the runway. This results in the plane being launched back into the ai
r. Depending on speed at touchdown this will result in small or high bounce
s.- "The monowheel can not be wheel landed" such as a regular tailgragger
.. The tail wheel must touch down just before, or as soon as the main wheel.
-
To get the correct picture of the planes attitude at landing, When you taxi
out for takeoff, and when you get the plane lined up and ready to come up
on power, pause for a minute, look at the far end of the runway over the co
wl. this will be your sight picture for the landing touchdown..

mono tends to bounce if not landed "on the point", but I never experienced
it in my past-25 landings so badly. Did anyone have a similar experience

Hello Frank,
I have a Classic Mono with the original red block, however, I installed
the shock absorber dampers. I fly exclusively off of hard surfaces (wou
ld like to try turf one day). I typically run about 22 psi tire pressur
e. I found that lower pressure results in the caliper rubbing against t
he tire which is located in the original position. I may try moving it.
I typically will have a slight bounce on landing, although I have not
noticed a big difference between 18 psi and 22 psi. I have had some rea
lly nice landings and some not so nice. During the flare I attempt to ke
ep the plane flying as long as possible before allowing the tail wheel t
o contact the runway first...stick back and she is down. If she comes d
own too earlier then a bounce is inevitable.
Check that you have the shock absorber installed. Good luck.

Erich is right. Don't let the plane land until the tail wheel touches,
then immediately pin the tail to the ground. You might get a tiny bounce
or two but nothing significant.
This is what I noticed in the early days, (flying an original Classic
with P51 style tail wheel) ;--
Just as you flare the wings come into ground effect and the tail loses
the downwash from the wings, result? nose drops. It feels as though the
airplane has stalled but it hasn't. Next, the mainwheel touches while
you still have flying speed, nose goes up with the bounce and she
balloons because you still have flying speed.
Because the airplane is at stall incidence when the tail is on the
ground, if the tail wheel touches first a serious bounce is not possible.
You must keep the stick moving back as you enter ground effect. This is
hard to remember while you're doing it but it works.

Frank, and others.
Great comments from you all.
Specifically Frank it sounds like you have an original mono with a stiff
bumper and without the shock absorbers. After consulting with Roger
Bull at the factory, It sounds like your aircraft never had Mod 29 done
to it.
As Roger put it, "The red shock absorbers are a very early design, and
have been superseded for many years by the black ones. Reading his
comments, I agree it looks as though he does not have the dampers.
There is a Mod for this - Mod 29. We have not used it for a while, but
he might like to consider it. The price would be =A3235. I have to
say, from memory way back, that the mono without the dampers closely
resembles a kid's bouncy castle on landing!
I am attaching the BOM, and the instruction sheets; note that the black
block now has all the drilling done. Since you are in Germany, you can
order it through Bruno, at:
http://www.europa-aircraft.de/<http://www.europa-aircraft.de/> or direct
from the factory. See
www.europa-aircraft.biz<http://www.europa-aircraft.biz/> or .com to get
your part order in.
Here's hoping a few hours work will cure your bounce.

Frank,
Congratulations on your starting on grass. Smart move.
I'll research the block with the company. Do you have the dual shock
absorbers installed? Refer to the new manual Chapter 29M
What is your main tire pressure? Many prefer to run a low tire pressure
to preclude bounce. If you've got it firm, you're landing on a beach
ball. Sounds like you've got the pressure up.
We inflated the only mono I have been in at 18 pounds on a 7 inch tire
and found it more comfortable with the pressure at 14-15 psi. The owner
prefers it at this pressure. The plane squats in on landing.
Love to hear other comments from you experience mono pilots on tire
pressure and concrete runways to get a feel for what works for each of
you.

Heck, I still get a bounce after 800 + hours. Actually I find it more
of a small skip than anything these days. If I get the main and tail
wheel down at the same time, it will skip a little if there is any
flying speed left. If I get the tail wheel down first, the I get one
of those greasers that lets get out of the airplane with a dopey grin
on my face.
Actually I used to find my Comanche a bit of a handful to squeak in.
After I was flying the Europa for a while and got a bit more bit more
disciplined about speed control I found I started landing the Comanche
much better.
Cheers, Paul
