Screamin Demon w/West 50V1 with tuned pipe question
Okay so I've gotten to the point where I need to mount the pipe. My only problem is the fins are going to interfere with the tuned pipe. I haven't mounted the fins yet, so maybe I can just locate them further outboard. Has anybody mounted a West 50v1 with a tuned pipe on this airframe? It's a side mounted exhaust. Anyone have any pics?

The header has already been trimmed down for an 8x8 prop. I've had the motor a couple of years.

Just bend the pipe coupler some if all alse fails.
It doesn't hurt, except for the coupler blowing out after 200+ flights. If it blows earlier you have your pipe spaced too wide from your header anyway. That engine is not that hot.
Don't move the fins, there's no need to.
Get some proper silicone tubing for a coupler...don't skimp and use cheap stuff...it doesn't last...

I think so. I can't see down thru it. Funny thing is, it sure is loud when I run it!

I have yet to build one with the standard center fins so have never had to deal with the interference problem with side exhaust and tuned pipe. My West .50 version has tip fins. They are more of a PITA to install but no big deal if you can build kits.
Did you put in some kind of hard point for the pipe standoff?
Get that engine singing on the right prop and you have a 170mph machine, maybe more but proof is in the radar gun. It will outrun a Magnum R on the same power package. Similar power to a Sport Jett .50 but needs less shaft load as it is timed a bit higher. Very nice engine IMHO, easy to handle. As per my PM, APC sport 9-6 is a great test flight prop - lets the engine spin in happyland, more pull from launch and top speed governed by the pitch/dia combination.
