The next thing i have tackled it the servo trays to install the throttle servo and the rudder servo.
I also added an extra ply wood to give me clearance for the servo arm.
Here you them both on a dry test in it's location i have not yet epoxyed them as like to do a dry test,
before i glue them and i still have to add some reinforcement with triangle cuts of balsa wood for the final fit.
