Status: offline 		Hello,

I am looking at mounting a pair of servos for the elevator in my
Extra 300s ARF.

The fuse is made up of 1/8 balsa sheeting down at the tail.

Is it safe enough to cut this then epoxy some 1/8 ply strips to use
as servo rails ?

My concern is that the servo hole cutout would weaken the
structure.

On the inside of that backplate I would mount two 3/8" hardwood rails for the servo mounting screws. Epoxy this structure to the inside of the servo cutout hole. Simply putting 1/8" ply for holding the servo screws is not enough IMO.
