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.

Printed battery box.

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.

Finishing up and testing electronics tray, designed to slip into end of ballast tank. End cap and tray single print, keeps things tidy when complete. Getting close to getting wet.

Just curious - is there interest enough in this project for me to post the STL's? No cost, but since Bob owns and sells the files it would be his decision. I don't plan on selling anything and some STL's would have to be purchased from Bob anyway.

If this works out I will probably re-work the full length plans to take my modifications but use regular twin ballast tank kit since I already have one.

I don't like the yellow - it's PLA glass filled, doesn't print well. Probably stick with white with red trim.
