Martin,
Not to pile on, but I have fit a number of large pilots to the Europa.
It has been my experience, that the only area of the tunnel that is a 
nuisance to the tall pilot is the area where the knee hits center 
console.  A football shaped cutout there is typically all that is 
needed.  I have seen some Europa's with the console cut down very low, 
and I share the comments with others that a lot of stiffness of the 
fuselage is given up by cutting down this area.  You are compromising 
the aircraft.  The Europa provides more than reasonable protection as 
is.  Short story:  On two nose low (25 degree impacts in landing 
accidents) one with the full console, the other was cut down a modest 
3-4 inches.  On both the floor of the fuselage behind the rudders 
flexed, which compromised that area.  One aircraft  had under the door 
electrical conduits installed of 4 layers of glass measuring roughly 3 
inches deep and level with the sill and a full console, with a cut out 
where the throttle would be.  This area was glassed in with a flange of 
4 layers of 8 oz bid and a cover panel of 6-8 layers of bid.  It 
maintained very good fuselage stiffness with only nose damage when the 
nose gear failed after about the 4th porpoise.  The floor had a minor 
deformity in the glass from flexing, but was easily repaired.  The pilot 
opened the door and stepped out.  The other aircraft actually split the 
fuselage side 6 inches forward of the door sill when the fuselage floor 
flexed.  The console was cut down some 4 inches beginning below the 
instrument panel face continuing all the way back to the bulkhead and 
had no under sill conduits.  The side of the fuselage cracked due to the 
nose flexing downward.  Some foot injuries were incurred as the fuselage 
flexed to the point of cracking from the consol up to the windscreen.  
Foot injury occurred as a result of the rudder pedals deflecting  as the 
fuselage skidded along.  Both accidents were pilot error and no names 
will be released so don't ask.

It would be best to make a modest console adjustment to fit your form.  
I have found for pilots your size that the hi top mod 63 is very 
comfortable and the extra width mod 67 is also a must have.  If your kit 
is too far along for the high top, the bubble door glass is one of my 
favorite mods also.  These higher top mods allow you to slide aft a bit 
and get another inch of headroom and less knee height.  All the above 
can be purchased through the company.  I know I'm kicking myself for not 
doing the width increase as it is quite comfortable.  The high top is 
quite impressive.  

As for how to re-establish strength in your console after cutting it 
out,  please properly prep and add foam to fill the void, prep the foam 
and add two layers of bid overlapping two inches around the hole on the 
inside and out...  As for the hole in the bottom, consider adding a 
bulkhead behind the nose gear of 1/8 inch (3mm) aircraft ply and 
glassing it in with two layers.  This is a help to stiffening the plane 
also besides allowing for a generous cooling air exit if the mono wheel 
firewall is removed.  Be sure to protect the new bulkhead and console 
inside exposed to the engine with firewall material of your choice.  
Then close the bottom hole, and if you like, add a large inspection hole 
on the bottom for maintenance of in console items.  A glassed in hole 
adds for stiffness and impact strength also.

Top it off with a back cushion about 1 inch thick or 1/2 inch of firm 
foam and a contoured seat cushion to suite and you will be comfortable.

  Hi To All 
  I have purchased a part built mono wheel kit and may want to convert

anybody done this and ois it a factory mod 
  Thanks M A B
