How do you know that your 3D printed part is strong enough to meet the flight loads? I’d hate to see your battery break loose in turbulence some day.
I considered that. Since this battery is only 4 pounds the forces it creates is a lot less than the 14 pounder that was there before. The part I made was able to carry my weight when bolted to a beam upside down with me (200#), suspended from a rope through the middle. I figured that would be equivalent to approximately 25g of the 4# battery. My wings are only rated at 4g so I think there is going to be a bigger problem before the battery departs the holder. Now what I am worried about is if the ASA filament will soften in the engine compartment so I am keeping a close eye on it to see if there is a problem there. I already have a nylon one that Justin (pilot here) printed that should take a few hundred more degrees in case this one fails the temp test.
