I think 135 is a little weak, but it's more the pilot than the plane because even a C is very capable. An S-1C with 135hp would be great for sportsman. Intermediate would be a good challenge too, but the judges will be straining their eyes as you climb up and turn that potential energy into kinetic! There is no replacement for displacement!

145lbs- perfect, dont change anything for a year.
Then id upgrade to 180hp fixed pitch.
Fly till the wings / fabric need work and only then think about a fully symetrical airfoil wing.
There is a Canadian and US company that make kit wings.
Join the biplaneforum and ask lots of questions..

Get copious amounts of spin training including inverted accellerated flat etc.
Hop on a plane go see CS or Harvs etc. for some training those little buggers wind up very fast when mishandled.

cosmetic mostly, a more modern look!
important things are airfoil and stiffness/ strength.
one good mod is a plywood leading edge vs aluminum.
makes a D tube shape
which is much stiffer and stronger than Al sheet.

by a flying plane only, nothing expired - you want one that flys 30 min a week min except winter and has a few hundred hours minimun TT and
has seen some light competition, beware very few hours and infrequently flown. beware fabric older than ~15 years, recover is big $$

As Peter says, buy a flying airplane -
not a project that hasn't flown in years,
which will require a lot of extra time
and money to get flying again.

By the time you overhaul the rusted-out
engine and put new fabric on it, you are
out tens of thousands of dollars and probably
a year, more realistically two. Plus an import
is going to cost you at least another couple
thousand dollars (for a homebuilt) for paperwork.

Suddenly that project airplane doesn't
look so cheap any more.

There was an S-1S out in Fort MacMurray
for sale. Lots of recent flying. Already
C-registered.

At that HP level you will be OK with sportsman but not so much with intermediate. To complete a intermediate sequence you will likely have to take one out to gain some altitude back.

There is a very nice Ultimate Biplane for sale in the the saskatoon area that is cheap. Low HP well built plane.

PM me if you want info.

There is not much energy difference between sportsman and intermediate, what they do is throw in some negative stuff and give you the occasional up or down 1/4 roll. I suspect that starting nice and high and with care in the cornering G it can be done. However if you need a break so what, still fun to compete and an inexpensive way into the sport and there are lots of mods you can do to upgrade later.
