Using Dubro mini e/z servo arm connectors to allow quick and secure adjusting of the pull-spring string at the servo arm. This is a testing mock up DLG boom (CF arrow shaft) with .062" balsa stab/rudder surfaces that use 4" of .014" wire torsion springs. The servos are 4.1g Emax ES9051 with a .8kg torque. The RX is an old Spektrum AR500 4ch (DSM2) with case removed, and the TX is the multi protocol Jumper TS8SG. The plywood electronics tray is hot glued to the boom is too wide and needs to be cut down a good 3/16" in width.
