Dear All
My test was not so good .
I use 5S 2700 mha , 13x6 prop
Fiorotti active timer .
the first 2 minutes was ok but after the motor loose power
I did 4 flight with different batterys with all the same result
After each flight I put the finger in the motor , if I leave my finger I could burn me .
the temperature was very high .
When I used Cobra or Eflite the temperature was little hot .
I think If I use a smaller prop and higher rpm the motor would work better .
But I can do more tests now , I have contest in JATAI state of Goias in Brazil .
A little far from home 800 miles , but one of best contest in country .
Thank you
Guil
