Two updates ago I noticed that my CrystalSky (9.8" H.B.) fan was not seeming to come on (I could not hear it come on) and yesterday (after latest firmware update) I flew in 70 degree weather and after a 20 minute flight the back of the C.S. was hot. This latest firmware update stated that it was to help a problem with heat management but didn't seem to help. I am concerned that the fan has failed but don't know of any way to verify that besides listening for it. Any one else have this problem and/or suggestions?

Thank You,

Ted.
