I run a few Brushless setups on my small-scale collection
There are a few things that can cause this:
Provide me with some info and I am sure we can get this resolved:
What battery pack/s (brand/voltage/technology) are you using?
Did you set the ESC up via the push-button method or do you have a MambaLink USB interface?
Did you try running the motor outside of the Micro? - As in not installed, so there is no load on the motor shaft..
This is a bit "n00bish", but you did make sure the motor wires are correctly plugged in white to white, red to red and black to black..
My suspicion is that the low- voltage cut-off may be set at 6.0V and you could be using a 6.0V pack, the LEDs will light up, but she ain't going nowhere
I do recommend the MambaLink USB interface with the new Ver.2 sofotware.
This makes setting the Mamba25 up a simple task, I find the push-button method is tedious
