Mainly, because I'm 6'-0", 280lbs. Yes, I need to
go on a diet and get back
to
205. :) I need
all the room I can get, and the Velocity XL so far,
seems to have the biggest
cabin/comfort. Just
crawled throught a Flying Fortress this weekend
at the airshow, tight fit.
They seem
to only make cabins for 5'-7" 150lb
male/females. Anyone have any
alternitives?

PS You know if the kit plane engineers made a
plane that carried (4) 6'-0"
guys, 200lbs ea.,
flew 250MPH+, 4.5 hours of flight, can't hold it
any longer :), all the
IFR/VFR and music(CD),
and lugage, the SUV of the air, they would sell a
lot of planes. I know they
call it a 747. :)

That why I have a Kis Cruiser.

What about a Super Stallion?

Take a look at the Express web site.  Their Express 2000 RG version
fits that bill.  It's a nice kit and looks great.

As for me, I'm trying to figure out what engine to put into my FT.  I
have an IO-540, but really want to go with a better engine.  I just had
a bearing fail in my Cherokee 140 after 500 hours since major and the
$15k repair bill had me sell it as is to the mechanic.  Time to be in
control of my own engine package.  The 20B would be nice, but I'm still
on the fence between the 20B and some sort of other piston conversion.

You won't find anything near the same durability and power to weight ratio
of the 20B.

Paul,

What about parts and availability.  As Tom Kendall is running into, the 20B
has the disadvantage that there is little documentation and few tools here
in the US.  I'd hate to go through all of the design work and trouble to do
a 20B install and then not be able to get parts!

What about doing some sort of twin arrangement with the 13B?  Do you have
some dimensions and weights for these (dry would be nice) that I could play
with in a CAD program to see if it is even conceivable to fit it into the
cowling?  I'm trying to match the 402 lbs of an IO-540 and at least 250 HP.
I really wish that Moller/Freedom Motors would get their butts in gear and
get some engines in production!  They must be having some problems with
rotor cooling along with the production financing.

There are only two parts that are unique to the 20B. The e-shaft
and one intermediate housing. All other parts can be 13B parts.
 The housing can be lapped when it is worn and the E-shaft never 
ever breaks. Even when putting out 900 HP. 

Bruce Turrentine builds 20Bs and he is doing a video on
the 20B overhaul as we speak. Should be available any day now.
Plus we have a lot of people working with them. Skip Vance
worked for Dave Atkins for years and I think he has some 
experience building them up. I know Dave Atkins has shipped 
several. Both Racing Beat and Mazdatrix also builds 20Bs.
Jim Mederer at Racing Beat holds the E class land speed
record in a third gen RX7 at 268 MPH powered by a turbo 20B.

I don't think Moller is having any technical problems.
Our man Jeff Spitzer redesigned the engine for liquid cooling
from the air cooled OMC version. Jeff is currently the chief 
engineer/manager on the Predator and very capable. One of, if
not, the best engine engineers I know.
