Mejzlik Modellbau used to list several ARFS but I couldn't find any at his website tonight.

I've still got a "generic" Russian plane from way back when Their FAI team made a "Barn Storming Tour" of US contests. This would have been shortly after the USSR dissolved. They brought over a lot of home built equipment to help pay for their trip.
Even though they don't fly .36 size combat competitively, they built the best planes..!
For 1/2A , Larry's LiteHawk is a good one with a hot TD, Norvel or better.
