Something to replace the Neptune - Short Typhoon?

[Ed Kirk]

I printed the main tank, both inner tube, outer shell and one end cap in single print then added 5 baffles and other end cap. I don't think the printed parts are water tight and will coat the inside with casting resin which is very slow to set and drains out leaving very little excess.

I am going with a simple battery, 12V NiMH (3000 MaH) and dedicated charger from Servo City. Both come with XT30 plugs and the battery has an inline fuse holder and fuse.

Battery box slips into cylinder using threaded rod to guide and hold in place, bow bolts on threaded rod locking in place. To remove battery, remove bow and slide out battery.
