I want to start running air filters on my HELI motors,

Where can I find these ?
I got a used raptor a few years ago, os50, it had a filter, so I know they are available.

Just about any rc car filter would work but it would be quite cumbersome to install and a bear to get in and clean under the fan shroud. There is one speciality filter made by audacity that you might find acceptable. It looks like it might fit the bill. http://www.audacitymodels.com/Produ...63/Default.aspx

went to the local hobbyshop with motor and fan shroud,
found one that fits in the shroud, but is much bigger that I really wanted. it's much bigger than the one that was on the old rappy.

I was able to get 8 test flights on it.
Did not notice any performance differences, and the motor did not over heat.
going to keep a close eye on motor temps, as it only 33 deg f

that one on that website looks nice, but model in pic looks like a 90size, way to big for my first test project.

I would imagine it is not needed to run a air filter , the way I see it is any particles that find their way into the fan are not going to find their way into the motor , being heavy they will get to the edges of the shroud , it would need to change direction and go into the carb , fairly unlikely id say ?

Until you hit the ground and the dust fly's. That's when a filter will save your engine.

I'm going to order a set of those to try out.

In 250 flights on one of my heli's I've had 2 broken clutches, and shortly after each clutch was replaced the motor blew.
Found very small metal chips on to of the piston, the same metal chips were found under the clutch on top of the fan, it was chunks of clutch debris.
2013's 3 bad clutches and 3 blow motors, 2 different models, each had hard chunks at the piston.

I'm not worried about the dirt or dust, that's part of crashing. But it will be a bonus reason for installing the filter.
