A nice RV9 was displayed at Sebring as a Light Sport airplane.[wood
prop,no wheel fairings,etc.]with a 120kt cruise.
As a starter to thoughts re the TR1[forget the regulation interpretations
for now]how about a simple new larger fabric /wood wing designed by
Rich,Mark,and others.
I am listening
Ted
PS The Viking/Honda engine package for a 110 HP engine looks like real
competition for Rotax.

Hi Ted,
When I was working at Tri-R I did a preliminary design for an LSA based on the
TR1. Mostly longer wing and bigger tail if I recall correctly. It could be have
been done fairly easy using the same construction methods as the TR1.
I also did an LSA design for a Chinese company that was built and flown.
In any case I do not think wood and fabric are the way to go. For the same strength
wood is about 3 times the weight of steel. Steel is about 2 times the weight
of aluminum. Aluminum is about 2 times the weight as fiberglass. So why
use wood? Of course carbon is about 3 times the strength as fiberglass but
costs more.
If a few people are really interested in making an LSA version I could design and
build a (full) wing kit and tail extension kit to make it meet LSA regulations.
Mark
