Problem with esc and receiver, Help please

[Zedrik]

I got the roster crawler and novak 45t motor, my transmitter is airtronics mx sport and receiver is airtronics 2.4ghz 3 channels.

well the problem is i connect everything, and im just getting reverse, the light when is neutral stays in red , when reverse it flashes green and when i go forward with the transmitter it changes to green but no movement.

i have tried changing the configurations in the transmitter but no results, i have reprogrammed the esc many times aswell.

please, can you give some directions, this is my first scaler and im getting a bit disappointed.

thanks very much in advance.

I see that there are 10 model memories in that radio. Are you using a new - everything set to zero / centered - memory spot?

Do you have other RC's that you can bench test on? Different motor in esc, different esc with motor, etc.

The best advice I can give is to just walk away and so something else for a while, come back and start at the very beginning.

Well, i went away for the day and i tried everything again, i dont have any other Rc on which tried the transmitter and receiver.

so i did some test with a multimeter trying to figure out what is wrong.

i found the followings


with the motor connected in reverse full throttle i got 7.8 volts. (full spin on wheels)
with motor connected forward i got 23.1 mVolt (not spin on wheels)


if i disconnect the motor from esc and i check voltage in the wires this is the result

with the motor disconnected in reverse i got sames 7.8 volts as with the motor connected.
with the motor disconnected forward i got 5.6 Volts,

it seems that when the esc is connected to the motor is does not give the power for forward.

i did connect the motor direct to a source of power and it spins normally


i dont know what else to do.

any suggestions about what could be the problem?
