Skip,

If you're not averse to profiles, I can highly recommend both of these for the Saito 100:

Mojo 60:

Sabre 56:

My Mojo 60 weighs 5.5 lbs with a Saito 100. It's a real dream to fly. Very easy TR's, almost no coupling for all KE moves (very slight roll, but no pitch coupling on my plane -- easily mixed out). IT's also remarkably tough for a balsa bird with the innovative fiberglass tube/integrated motor mount. I found assembly actually FUN with this method of construction, as most everything self jigs on the table.

I've flown the Sabre also, and it's a great design-- very similar to the Mojo 60 in performance.

happy hunting,
Joe
