Default Receiver heat sensor

I searched these forums for "heat sensor" and found:
"Some ESC's have a temperature sensor to prevent this"

I assume ESC means the receiver/servo package in the aircraft.

Anyway, I flew my Firebird Outlaw this morning and was timing the flights and getting used to flying in a very light breeze. The batteries run about 9 minutes. When I put in the third battery the props would turn momentarily but that was it. The fuselage felt slightly warm so my guess is that there is a temperature sensor on the circuit board of this cheap little Hobbyzone airplane.

When I got home I checked the third battery to make sure it was fully charged and the motors ran fine.

Default 30 minutes to cool off

Apparently two batteries worth of flying then 30 min of cool down is required for the speed control. The air temperature when I fly is about 72 deg F.

I drilled a 3/8 in hole in the battery cover and two in the pylon just below the wing for ventilation. It might not make much difference.

That thin plastic sure is tough.

Default It is the battery stupid

With three identical batteries I apparently used the bum one last for two days of flying.

I finally marked them and found the bad one.
