Plane Engines need Air Filter?
My combo from tower came with everything, engine and all. But it doesn't have an air filter on it.
I come from the world of RC cars and we ALWAYS had to have a filter on it. Are planes different? I can see why you dont need one in the air but I mean landing and takeoff or even a crash can lead to dirt getting in.

If you don`t take off from very dusty ground you will not need an airfilter on your aero engine. I too run cars and airfilters are mandatory on them but I have never used one on my plane engines

Some engines used to come from the factory with Perry carbs installed (K&B, HB, Irvine - a long time ago). Perry, when Perry was actually Perry, used to provide a line of air filters for those that just couldn't resist - at a fee, of course. <G>
They kept the June Bugs and pieces of gravel out of the engine and they even improved the fuel economy somewhat. I've never heard anyone go so far as to say that the air filter improved performance at all, but at least they didn't hurt it too badly.

Well our landing field is low cut grass. Every now and again the prop will "cut" the grass just a bit and im worried about a pice of grass getting into the carb.

I live (and fly) in the middle of what is one of the world's largest plantations of pine forrest and during the spring, the air is quite literally yellow with pine pollen.
If you fly during this period, your model comes down covered with a fine layer of pollen -- and that pollen appears to be very abrasive (like fine grit).
Suffice to say that I bought some air filters for my engines :-)

Hey Ed -
Here's someone who claims improved performance from a filter!
[link]http://www.rcuniverse.com/forum/fb.asp?m=5012118[/link]
Actually the reason that he uses sounds quite plausible!

How well do these filters stay on.
Ive tried other filters. Even using cable ties they do not stay on.
I havnt found a shop selling these Bru Line.

Bruline: Exceedingly difficult to install, in some circumstances. Others, are a walk in the park. If you are lucky, your carb has a long enough venturi that the Bruline easily slips over it and is secured with a zip tie.
In the case of the Webra 50 in my photo, it was a real test of patience and manual dexterity. The zip tie walks a fine line also, between holding the filter on, and squeezing it off. Most engines (carbs) are not this problematic.

To PlaneHeli
I noticed you're from Oz (possibly)
This shop is located in WA but their supplies are tied into a national buying / selling group that supplies all over Oz. They have the Bru Line under Fuel and Air Filters in the accessories area of Air Circus.

I use Bruline filters on TT42 GP :fits easily on carb neck without needing any ziptie,it stayed there.
SK 50, needs some work to fit it on carb neck but no need any ziptie.

There you go. It just goes to show you that the word performance does not necessarily mean more rpm.

RE: Plane Engines need Air Filter?
It's not unusual to see a filter on an inverted engine in controlline circles--especially if the model is sporting a custom-modified (expensive) engine, which many of them are. Once installed, they are not much trouble and give some piece of mind about scooping up debris while the model is on the ground. Some who have converted modern glow engines to diesels with conversion heads use the Bruline filter body as a "holder" for venturi restricters on their carbs. (Many diesel conversions don't need the intake to be so large.) Good luck, Dzl

I hadn't thought of using them that way before. Thanks for the tip.

RE: Plane Engines need Air Filter?
Yup. You can cut a bunch of them from the bottom of a margarine cup (or similar), then punch different sized holes in them to find the one you want. They will fit back into the filter body with the filter--you just have to work at it a little. Works fine. Not my idea; I got it from Davis Diesel. Good luck, Dzl

Since the Bru-line company and the original Tower Hobbies is gone now, where can someone buy an air filter for a 60 sized engine these days? Looks like because many people are switching to electric the demand for air filters has diminished so much that the companies went out of business.

There's a boundary layer of dirty air, thats why cars and trucks that run nitro generally run air filters, I've flown off most of the flying fields in the south east and never ran an air filter in an airplane, they are simply above all that unless you're flying through dust devils.

The shop is still with us, operated now by his son, Matt. Last I checked, Matt still had a decent supply of the filters.
You can do a web search for Prop Shop Hobbies on Van Dyke Avenue in Warren Michigan. Probably best to call and ask for Matt as the newer folks may not know about the filters.
