There is a specific calibration procedure, have a check on the castlecreations.com website for the manual, but its basically:

1) connect batts to esc & turn on
2) hold full throttle on the radio & turn on
3) wait for beeps & led to change color
4) pull full brakes & wait for beeps + leds to change color
5) release to neutral and wait for beeps
6) esc will beep arming tone and then be ready for use

Make sure all your throttle trims are at neutral and the epa is set to 100% for forwards and reverse, and the throttle is in 50/50 mode ( not 70/30 or 60/40 etc ).

You can rig up some mounting adaptors if you really want to use the metal chassis, just a couple of strips of aluminium with 4 holes in each to line up with the mounting holes on the tranny & the chassis.

If you just want a metal chassis though, look into the FLM 3905 chassis, will work perfectly with your parts & is much stronger than the stock nitro chassis- and longer too.
