Hi, Bill.
I have flown the Surpass .26 on a Flite Streak, Ringmaster, Sterling Mustang and Nobler.
I flew THREE of them on "The Plane ^ 3".
The best combination was the Mustang. It garnered me many trophies in OTS, Profile, Classic and yes, even AMA Advanced.
A two ounce metal tank with non-uniflow, atmospheric venting works best.
Don't bother with the muffler.
The Surpass definitely runs better on its side.
