This fix will stop your fan jamming up and shortening its life and effectiveness.
I was very dissappointed with my new 9500 ESC when I discovered the fan jammed 9 times out of ten after landing jumps of various sizes. Notice how you can easily jam the fan by pressing on it ever so slightly with your finger? I'm just guessing the force of landing a jump has the same effect. Here is a fix. Enjoy :)
Materials needed-
1. Less than 1cm of BIC biro plastic ink tube
2. 1mm thick piece of hard plastic cut into a square about 3mmx3mm
3. Gaffa tape (Don't laugh )
4. Super glue.
STEPS
1. Remove the four screws that hold the fan on the heatsink.
2. Remove the roumd sticker on the bottom of the fan. You should see the motor pin.
3. Sit the small 1mm thick plastic on the motor pin. Put small bit of gaffa tape to hold it there.
4. Cut the biro tube about 1/4 of a mm more than you need.
5. Dab glue on one end of tube and jam it firmly into the center of the esc heat sink. It will fit perfectly in the heatsink because there is a point in the center of the heatsink.
6. Screw the fan back onto the heat sink. PAY ATTENTION to the fan not being pushed up. This means your plastic tube is not short enough. If the fan not sit firm enough on the bic tube, you-tube is too short.
When you are finished, the fan should spin as normal, and while it is spinning you will be able to tap the top of the fan firmly and it will not jam. YAH!:)
