Henlong 1/16 Jagdpanther Tank Visaton FRS 8 Speaker Enclosure

This isn't plug-and-play. My tank was a 27MHZ model, which I swapped out for a 2.4 GHZ version along with several other modifications. The resulting design cuts down on unnecessary bumps and mounts that were in the way, allowing it to fit snugly against the battery box top. A lip on the lid ensures a secure fit into place. To assemble it, simply apply hot glue to attach the lid to the case, then use screws to hold the speaker in position or opt for riveting like I did. A bonus is that cutting the design flush with the battery box top creates additional chassis cavities that boost overall box volume - those holes at the bottom of the box serve this purpose. Use hot glue around their perimeter to seal them to the box. Another bonus: by matching the box width to the interior of the chassis and applying a bit of hot glue on both sides and the bottom, you'll significantly stiffen the chassis once the lid is in place.
