Habu SS Battery Tray
Description
I felt there was not enough surface area to use stick-on Velcro to secure the for and aft movement of the battery and then pull the battery out to replace the battery. I drew a battery tray in Autodesk Fusion, but realized if I decided to use different size batteries, the battery would need to be moved for and aft as needed, so I redrew using parameters. Hopefully someone can benefit from my work. Parameters used (see pictures to help with description). All measurements are in inches. CBW - Cross Bar width. These worked for my model but may need to be adjusted to fit yours CBD - Distance between cross bars. These worked for my model but may need to be adjusted to fit yours SL - Length of stubs that keep tray from sliding front to back The stubs fit between the cross bars ST - Thickness of stubs BL - Length of battery. This length should match your battery. BSL - Length/Height of battery stops. The battery fits between the stops and keep the battery from moving front to back. PTH - Plate thickness PWI - Plate width FL - Fillet/Chamfer size BD - Distance between front of battery and front of front cross bar. This distance helps with CG of airplane. You should balance the airplane as the directions specify and then measure between the from of the front cross bad and from of battery. My Habu SS, using the HBC 4000 6S battery balanced with the battery .96 inches from the front of the cross bar. With my setup, I cut a small block of foam from the packing material and used the Velcro straps to hold the front of tray.
