Help!
~Exhaust Deflector~

Question; When I mount the "Exhaust Deflector" Is it a good idea to use a small steel hose clamp, Instead of the tie strap they send with the Exhaust Deflector? I'm thinking it may blow off with the tie strap.... I'm thinking the steel hose clamp will hold the deflector on better.... Your thought's please!!!!

It's about 50/50 if one is better....

Having the muffler cleaned of any oil,and dried, before installing the deflector is a big help.

I've used both-and I prefer the steel clamp,myself.-It's very easy to snug it up , on occasion. Just for peace of mind.

If all of the above fail for you, drill a small hole all the way through the stinger and use safety wire that goes through the stinger and the deflector, wrap it around and using pliers twist it on tight. It will not come off.

Lud,


I suggest you forget the whole thing...

This exhaust deflector wasn't designed to work with your particular engine; and your engine was definitely not designed to run with it.
I still have an engine that the mere installation of this item on its muffler spigot, instantly shaved over 1,000 RPM off its top-end...

This item will not keep your plane clean. You will still need to spray-n-wipe it at the end of the day; maybe just a little less. So, it obviously does serve its intended purpose.

Just forget it; and it you didn't buy it yet, just leave it to rot on the LHS shelf...

As long as you run a glow engine, you'll just have to keep on wiping...

I usually take my Dremel with a cut off wheel and CARFULLY cut a shallow groove around the exhaust outlet. I angle the wheel so I have a 90 degree corner closest to the outlet and it tapers to the muffler. The exhaust deflector material will deform into the groove making it difficult for it to come off. This groove is commonly called a hose barb. Google "hose barb" and you will get a good idea of what you need to do. I've found a singe groove is sufficient for our purposes. It does not need to be very deep. No need to use any sealant, just clean of oil.

Jim,


Model Diesels are not so adversely affected as glow engines are, as far as power is concerned...
But the model it is installed on will still be slimy at the end of a flying day... Maybe a bit less slimy, but gooey still.

And, what Diesel is that? It looked like an MVVS 2.5 at first glance, but then I saw it is not...

Thank's Ken.. I was thinking about doing this as well... cutting a small grove around the pipe. Then i would use a small steel hose clamp....
