muffer exhaust angle
I noticed on my .40 size engines, they all came with different angles of the exhaust port on the muffler. I know you can change it, so... seems to me 90 degrees straight out leaves the least grease on the plane, 30 degrees down leaves more on the bottom of the fuse etc. My question is, does the angle affect a thrust vector and thus the trim? I'm thinking it would be minimal, and I'd also think 90 degrees straight out would leave the least oil on the plane. Fill me in. you experts!

RE: muffer exhaust angle
The direction of the exhaust port has no practical effect upon the airplane's flight characteristics. As for best results for a clean plane, that often depends upon whether it's a high-wing or low-wing aircraft. Straight right isn't a bad place to start, though.

RE: muffer exhaust angle
Um...why did you quote you?
I have seen, but never bothered to try this. Some guys run a tube from the muffler to the LG; to eliminate 'glow gook'.
Run as fast as you can toward gas, electric or both. Glow is just not something I want to bother with anymore, you'll see.
Good Luck

Adding extra tubing to the exhaust will reduce engine power output in almost every case and can cause overheating.
If it is an exhaust that you can rotate eg ST 90 then it makes no difference which way it points.

RE: muffer exhaust angle
on our mosnter trucks, we use EXHAUST DEFLECTORS, basically a silicone tube that diverts it further away
(and hopefully under the wing and away from the fuse)

Most short tubes used in the exhausts ( such as the Dubro ones ) are short and wide enough that any impact is miniscule.
This is something I've tested with interest since I'm looking to keep my muffler HOT for my smoke systems...
The tubing did not impact temps in the least... and I wish it would have.

I didn't realize that monster trucks had wings on them.
