Maybe it's time to cut the losses and put the equipment from the decathalon in a pattern airfame. The .55 AX would be great power in a Venus 40,
Oxalys 50, Groovy 50. These planes are made for pattern and you can stay Straight and level (pun intended) on your path. Many people here will
reccomend airframes that fly pattern well, but none of them fly like a pattern plane.

Good luck and I hope to see you flying at Jackson
