Could it be that ZK-CAT is perched on a PA38?It looks like a Nanchang [or possibly a Yak 52] in the background, but I have no idea of the engine make/model...
Cat perched on a PA 38-112 Tomahawk and the engine for the aircraft in the background (ZK-YAK??) is a Vedeneyev M-14P rated at 360 HP.??Barry
