Do you all use an air filter with your OS .32SX-H and what filter do you use?

Nope, don't use a filter on my OS 32. Haven't found a need to use one yet. If I flew over dusty fields I would definitly consider using one.

Yes, I do. Bruline / fine filter on my 32SXH; you will need to readjust the needle valve for the filter; I found that my engine needed to be leaned a little with the filter on.
I know most people don't use filters unless they're flying off the dirt but I feel better if the engine is sucking clean air!

I use one, never even considered not using one, especially with a heli. It just makes me feel better to use a filter when any engine is sucking air from the outside world. Have you ever looked at the fan on your engine after it has been run for a while........is it clean?

Rain has kept me in.

Ok so I agree clean air is good air. Any tips on which ones are best, and what type of maintnance schedule should be kept. I know some filters on cars and bikes are washable, but not sure if this aplies to model engine filters.

I use a Bru Line filter (fine) on my heli engines. You can buy replacement filters for them for around 3.00 for two. The inital is only about 4.00. I wash mine out every couple of gallons of fuel (not on any schedule) ocassionally according to how dusty the conditions are when I fly. I only replace them when they start to show signs of deteriating (spelling?). Of couse they are cheap to replace. I use a zip-tie to hold them onto the carb. I don't know about any of the other sites, but Tower carries them.

I do....

blacktop surfaces are dirty!! I use the one from century, fits o.s. .32, cost about $6, better quality than the bruline, which will eventually fall apart and could suck the foam into the carb, the one I have has a very fine metal screen.........you will need to cut some clearance into the fan shroud for a filter.....fritz
