I built the Ultra Stick 60 using some of the ideas I saw in some RCU posts (rear mount rudder and elevator servos). For any of the folks out there that have done this too, I was wondering what you did to reinforce the holes in the fuselage that were cut to install the servos. I cut some small spruce strips and CA'd them on the inside of the fuselage so the screws holding the servos would have something more substantial to hold on to. Is this enough, or is more reinforcement needed?

Thanks!!!
