Seems that the engine manufactures have given the smaller size market (i.e. 60 or less) to electrics. Is there anyone still doing these smaller size engines?

Hi, Dennis.
Sadly, I'm not aware of any.
My all-time favorite is still the SAITO 30 and I'm pretty sure it's out of production.

Saito FA-40A is still available. No shortage of NOS and secondhand stuff available.

Saito still makes 40: https://www.saito-mfg.com/productstop/products-4st/fa-40a/

Is the Saito 40A and AAC unit? The site doesn't give detail accept weight 10.3oz, not bad. Says like an 11x6 prop? What would we use for stunt maybe a 12" diameter maybe 7" pitch?

Site also has the 62 available.

Yes its AAC.

I'm running one on a 55 oz profile warbird.  11-6 APC sport prop at 9,200 rpm on 15% nitro fuel (300 rpm below peak to ensure slightly rich)
