On the 31st I posted the problem of FS locking up at random times while flying. This morning I measured the temperature of the heat sink on my GF4 MX420 64meg while flying. The temp reached 119 deg F. I installed a fan to blow directly on the sink. I have been flying multiple acft for 12 hrs, all sliders
max no problems at all. I have no idea if 119 deg is too much for reliability or not? Appreciate any observations in this regard.
