Hello Paul,

Yes, tube notching is an art, as is designing and welding...

Our mission is to build an airplane that complies with the intention of
the LSA rule. That is, to build kits, and eventually SLSA after
certification, for a relatively affordable price.  Our design three years
ago would have blown out the market at $40,000.  As a very small
company, progress is slow...  Since then material price increases have
ruined all our best plans...  we are still hoping for less than $45,000
for a SLSA that is a max  envelope performer.  Our web site is very
dated so I am reluctant to give out it URL.

A big part of the price is the power unit.  Moller  had
proposed a price of $2,600 per unit in quantity.  Realistic for that
time circa. 19??.  At the time of our introduction, the (rotary) engine
manufacturer we were working with had proposed a price of less than
$6,500 for a 120hp unit, ready to install, dry, and about 110lb.  We are
still working with these people to produce a cost effective rotary
unit.  And, we are still working toward offering an affordable LSA.  Of
course all design ideas are welcome...  We are doing our best to reduce
weight and improve performance at a cost effective price.

Turbo compounding??  I very much want to do this...   Right after I get
the airframe production going,  and customer engine requirements done,
and the rotary engine installation complete, and...

Sincerely,

Dan

How much of the airplane is tubing Dan? Do you have part drawings
on all the tubes?

I think at this point a 120 HP rotary at 110 pounds including PSRU is
unrealistic. Moller has never be known to deliver anything.
