I bought this motor sometime ago , same weight of Cobra 3520 and EFlitec32 .

My plane is a little heavy , almost 2000 gr . I was using cobra or Hyperion motor .
What do you think?

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

Dear all

I did today  a good flight with this motor
I īm using 12x6 apc prop  and Fiorotti timer

I did 2 flights of 5 minutes  , no problem with the motor
My plane is a Legacy converted to eletric , my old Legacy
I think this motor is a good choice and cheap

thank you

Guil,  wish you good luck or performance with your set up.  I sit here now thinking 800 miles for a contest, but it hit me that not that many years ago most contests for me was over 200 miles and several were in the 550+ mile range with our nationals being a 1400 mile trip one way.  With Marcus no longer with us I hope you can give us a good report on the contest and the fun you guys have.  When I seen the photos of the guy/gals and the feast after flying all day made me wish I was better off financially so I could come to you country and join you guys.  But, any way have fun and do good at the contest.
