Download the manual for the ST-M also. It has some better details than the STA manual does.

Be careful when installing the wheel pants. There was an on-line article somewhere that had a better mounting technique that helps to make them stand up better to some abuse. Dump the included landing gear and go with the Robart struts.

This is a good build article too- http://www.geocities.com/jbrundt2/ST-M.html Even though it's for the ST-M, it as some nice details that will set off the STA better than stock.
