Default Installing boom cover - nervous

I am a bit nervous about installing the boom cover. Specifically, it has maybe a half MM of clearance between the cover itself and the frame. To get the boom properly secured I normally torque the longer screws a fair amount.. I would think the CF deformation would stress the cover.


It sure is pretty now. I want to make sure it stays that way when it is all put together.

Mine was the same, perhaps worse about 1mm of clearance between frame and cover. It went on fine but after a few flights a hairline crack started to appear underneath. I added a bit more epoxy on the inside of that area and all is well so far. (for at least 20 flights now).

Thanks for sharing, Simon. What do you think of shimming between the cover and the frame? I would think some wide shims would work well. I am unsure where to get them though.

Maybe shims would work, I don't see any harm as long as they're not metal. I'd prefer my method, as a stressed part actually becomes stiffer, and just put it on as is. If you're too worried, perhaps apply a thin layer of epoxy on the inside of the cover which can act as a shim,

This isn't a bad idea. I tested the fit again and the only real gap is where the bottom screws go.

I'm probably just a little OCD... I have all the parts and haven't even started the build yet.
