probleme mit mex mv120A !

[mr ice]

Hy!
I'm sorry but i can't speak so gut german so I will write in english language
I have a little problem with a brand new Model Expert mex mv120A from Schweighofer.
http://www.der-schweighofer.at/artik...mex%20mv%20120 (http://www.der-schweighofer.at/artikel/71184/?query=mex%20mv%20120)

I have conected it to a brand new lmt-lehner 1535/5 hi-amp and when I want to start it, the motor vibrates for aprox. 0,5 to 1 second and then it starts spining normlay...
I know that the problem iz ESC, because I tried with a turnigy 80A ESC on it and it works fine...
I tried all timings and it is all the same...
I can choose 4-10, 10-20, 20-30 degrees

please help me if you can...

How many Lipos do you connect to the ESC?

The MV Version works from 3-6 Lipo-Cells, if you have connected only two cells, maybe that´s the problem.

[mr ice]

on the esc is a picture... 2-6 LiXX/6-20 NiXX

but I have tried 3s lipo too and there is no diference...
thank you for the idea!

Hi,

thats exactly what my Hextronik HXT 120 ESC does! Your ESC looks very similar and has the same specs ... perhaps it is a clone / is sold under the Model Expert label ...

this problem is known as "rough startup" in combination with 2-pole motors ... you can do nothing, only change the ESC or use it with an outrunner.

:thx:
Will be anything wrong if I run it?...
I start it only on the bigining of a run and than is full gas to the end of the race.
