It was the 607 FS that came with the module for my 9C.
I figure it was a combination of small plane, batteries running warmer in the heat, more warming from the speed controller and to some extent a lack of cooling air travelling through the fuse. But I won't be flying again when it is hot, too big a risk. |

I think you really need to add air vents to the fuse to circulate air around the Rx if you're getting heat related problems on FASST at only 90+ degree temps...
