I saw some long tubes for doing just that in the same area (muffler accessories) on the tower hobbies site. Might be worth checking out. I think the deflector should be sufficient. I don't have one on my plane and I haven't had any problems. I have my cam in the same place. I did rotate the exhaust nozzle on the muffler to blow down and left (if your looking at the plane from the front). Give that a shot. Also, check to make sure you aren't getting leaks from around the cylinder head. I have an OS 46LA on my Voyager that leaks around the head. Still runs good though, but I do get oil on my canopy.
Also, I got an OEM version of Power Director Pro with my Aiptek DV3100 camcorder. I just may have to upgrade for that PIP thingy. That is just too cool!!
