I have three concerns with the setup.

1. As Jon Lowe mentioned the anchor points of the carbon rods in the side wood strips is a concern. A) the strip could break where the wood is weakened due to the drilled holes and B) given stress from the elevator pushing up (or down ) flex could cause the rods to pull out of the holes.

2. Though there have been comments that the stresses on our elevator servos are not that great, I have seen in a DEPS systems slight movement of the elevator servo torquing (rotating slightly) when the elevator is pushed to an extreme position. Granted this probably means the elevator is pushing too far, but it demonstrates that resistance causes the elevator servo to want to twist and from the picture it appears that the rods will not be great against this twisting action. If I could put my hand on it I may feel differently.

3. The hole drilled through the ply that allows the rod to slip through (beautifully done btw) is also a concern. From my point of view you’ve completely separated the middle layers of the ply laminate at the ends and I’m not sure how much pressure it would take to cause those separated middle layers from slipping out. The only support they have is from glue on their neighboring layers above and below, and the surface area above and below the end ply section is very small (particularly the front joint). I hope that made sense.

Your work is beautiful and perhaps like Arch said will be fine, I’m just giving you my opinion. It’s worth what you paid for it.

A good idea might be to build another such mount and push it to the breaking point to see how much it will withstand.

Good luck,
