RE: A Classic with Class- Bridi Super Kaos .40
I am still flying a Super Kaos 40 I built 25 years. My first one was with a K&B 40, the standard engine of the day. Now I am using an OS 46 FX and that is plenty for me. An OS 55 AX would be like putting a 60 on it 25 years ago. I have a Killer Chaos to built and bet an OS 55 AX would fly it fine for sport.
