I have ABS Enclosures for sale. I am a one man show. Not a business so, I would prefer to use Ebay if that’s alright.
Made in my shop from 1/8" Vacuum molded ABS sheet. Middle will hold 2 up to 2 4s 10ah Lipo batteries (MultiStar High Capacity) or 2 6s 5ah Zippy Compacts. ESC area can fit the Castle XL2 or any other 1/8 or 1/5th scale car esc. I added an extra space in front of the batteries for other electronics (bec, on/off switch, charge ports, led…etc.) Batteries and other mentioned electronics are not included.
This case comes trimmed. and ready to install. You can velcro it or fasten it to your board with t-nuts and screws (not included) If you fasten this enclosure with screws it will conform to the shape of your deck. Concave is not an issue. It is slightly flexible material so if your board is a little flexible it shouldn’t be a problem.
If you would like an enclosure made to your exact specifications let me know. I can make a mold for $80.
