The manual for the kit builder instructs you to bend radio control connection bars for servos and controls to a slight "Z" shape. The manual doesn't mention that there is a special tool for creating the proper bend, appropropriatley called "Z' Bend pliers. Take my word for it, don't try it with needle noses. It's $14.95 worth of frustration saved. Do your math on your dollar cost to frustration level; then go to this website, http://www3.towerhobbies.com/cgi-bin/wti0001p?&I=LXL475&P=0
