G'day Rohan,
Congrats on your LX90 it won't dissapoint you.
A couple of helpful hints. Make sure you read the manual.
For accurate GoTo's Calibrate Motors then Train Drive, in that order is important.
Turn on Cord Wrap and you won't hear crack!!!!!! ever again.
Also go to Weasners Mighty ETX Site it is all relevant to the LX90.
