SE­CURE SERVOS

Model Airplane News - - TIPS&TRICKS - Craig Wil­liams, Pitts­burgh, PA

With large and gi­ant-scale air­planes in which the aileron servos are se­cured un­der flush-fit­ting hatches, I re­place the typ­i­cal 3/8-inch-square spruce mount­ing rails with thicker and wider sup­port blocks. If there’s enough room, I dou­ble the width to 3/4 inch and make them about 1/2 inch wide. Plus, I use thin light ply­wood to add re­in­force­ment gus­sets to se­cure the rails. I also use 15-minute epoxy in­stead of CA glue for a sturdy glue bond.
