Hello again, This morning i go to the track for some testing, include the weird phenomenon with my motor. The day is sunny, 30ºC and the track are 58ºC, is hot, my old Sorex 36 are rip
I retire the nylon washer, in the back lid, my first pack run 6:30 minutes, in the morning the track are at 43ºC, the motor not fade at any moment, but finish at 78ºC, and ESC 70ºC.
In the second pack, not fade, and temperature raise to 84º motor, 76º ESC.
In the third pack, not fade again, the temperature are dangerously high, 86ºC motor, 82º ESC, only 8 flashes to cut, at internal check temp. i feel, a soft motor at 4:30 minutes.
In the next pack, i put a dissipator in motor and fan in ESC, the temp low to 60ºC in ESC and 80ºC in motor, with not sintom of fade, and 7 minutes run.
I run a 6 packs in total, and not sintom of fade at any moment, the motor are fast in all packs, the back lid are deformed and i change for a new one.
I don´t know is the problem are the Washer, the lid or the temperature, but when the problem happens the batteries run 5 minutes right and now 6-7 minutes.
I take a temperature with a Exergen 301, is a infrared termomether used for nitro motors.
Well, i continued probed and next will compare with the 4.0
