As far as I know, OS made the smallest 4S engine, a Non-Surpass .20.
I have a few of them and they're great little powerplants.
One of them is in my Cardinette* and besides pulling the plane quite well, it requires around 1 1/2 ounces of fuel for the pattern.
No muffler required, unbelievably quiet.
9-6 Master Airscrew plastic prop, Brodak 10-23, 50/50 castor synthetic, 55 foot .012 lines.
It was replaced by the Surpass 26 which appears identical in size and weight and has a tad more power.

* plans may be available from Brodak.
