Jeff, I thought the Surpass-90 was no longer available, but here it is again. I flew this plane as a Fliton Infinity with an OS-91FX, but it is actually designed for a 4-stroke. Your Saito FA-100 will be perfect for it!!! The OS with header and pipe is 890 grams, so heavier then your Saito, and with this, the plane was less then 3,5kgs (<7 lbs).
I would absolutely recommend this airplane, just strenghten the wooden engine mount and the landing gear plate before your first flight.
