Installation of battery tray

I’m using this nice model , the same as the one installed in the Leader G.
The difference of the new one are the PLA 3D printed parts.
I changed the carbon rods with an EASTON arrow, carbon plus aluminum inside …. recommended by Gregg OKERT 20 years ago
The Easton arrow fits perfectly the news PLA 3D printed supports - slightly larger diameter.
As the previous model was all carbon replaced now by a part in PLA 3D printed, I did a modification I used a 6 mm diameter carbon fiber rod reinforcing the printed parts which in fact hold all the battery weight. This rod is flush to the sides of the support and is mechanically blocked on the front and rear main supports .
I did some checking - thanks STEVE - and it seems that CA bonds OK to PLA 3D printed material.
So as per BVM recommendation I used ZAP A GAP, and will reinforce with some BVM Aeropoxy.
Installing the battery tray takes time, but it’s a major part and need to be well secured.
Removable, you have access to the landing gear box, in case ….
The battery tray must be installed 97 mm below the fuselage where the canopy is standing as per BJ recommendation.
I don't use Velcro for securing the batteries but this non slip material.
