Firstar 2000 V2 battery holder

thingiverse

I'm designing a custom battery holder that perfectly fits a 49mm wide battery, similar to the Multistar 5200 4S model. To secure it in place, I use Velcro on the belly of my firstar and also attach it to this mount with more Velcro. A battery strap is then used to keep the battery tightly fastened to the mount outside the model before carefully placing everything inside and making any necessary adjustments for optimal Center of Gravity. I've actually removed the internal mount at the front of the plane, but I'm considering upgrading this design in the future.
