Some time ago word was going around that a heat sink won't be able to lower the heat significantly.
Today I measured the temperature of two more flights, giving a total amount of 6 times flying with heatsinks installed head and tail.
It does help a lot! Not only during the flight, but the cool-off effect after landing is also much faster...
I didnt look at the temperature at each flight. But the head + tail motor are still running smooth after a total of 48 flights.
more interesting are the temperatures measured at the main motor because i didnt measure the tail motor's heat until i installed the heatsink.
the temperatures of the first few flights were lower because i was very carefull not to destroy the mjx instantly.
The first higher peaks indicate when i was able to fly harder.
