RE: phoenix decathlon
Jason,
Looking good, did you add a screen to the air intake? Hope that will not make her run hot!.
After posting about the exhaust ext. I checked mine and just touching it, it fell off!! The tip of the muffler on the OS is very short and not enought grip with the plastic ties so I've modified it. I used wire/plastic ties like cords are wrapped with. Threaded two thru the tie downs and then added a screw on each side of the inner firewall, wrapped around and secured so you have a pulling effect on the ext to the front. I'm sure this will solve it and not loose it in flight.
