Artisan, I used a 9/4 on the St. 23 also. I flew mine with ailerons and just had a ball. The St. 23 was tight fit, so I imagine the OS .35 was even tighter. I did see a lot of .35 powered Falcons fly well. I built mine light and learned that a light airplane always flies better. Tose old ST carbs were a joy to run for me- so easy to set up. You just couldn't get them to run right with a closed muffler with that sub- induction porting, though. But they would last forever. Who can forget the sound of a ST Bluehead when you throttled back and it made that " ring a ding,ding" noise?

Yep, I remember that distinctive mumbling, ring-ding-ding that the old Bluehead G60 made. I still have mine. My old Fox Eagle .60 (baffle piston) used to make a similar sound.
The old ST carbs were sweet and easy to adjust. In the later Seventies, I bought a G23 that came with a bolt-on muffler. It idled and transitioned fine, but I do remember issues with sub piston induction here and there.
I still have a couple of G20/15 R/C engines that I have been holding on to, but my G20/23 went bye-byes in the early Eighties on a deal that I couldn't resist.
I built a Falcon 56 for a friend once. One of the leading edge pieces that came with the kit was so hard and tough that you could have used it for a night-stick. I called Goldberg and they sent me a new one, on the condition that I returned the old one. I've often wondered what they thought when they got it back. <G>
