OOD Proton Pack Rival Hopper PRE-ORDER

The Proton Pack is a custom-designed, 3D-printed hopper feed system that allows for a feed rate of 20+ rounds per second. This is offered as a do-it-yourself kit, or a fully assembled and pre-soldered unit. 

*Do not use new Headshot ammo with this product, the rounds are too stiff and can damage your connected blaster*

The kit version requires soldering and assembly. Both versions will require a 3S Blaster or other Rival blaster such as the Perses, Zeus, Hera, Khaos (adapters sold separately). 

FEATURES:
• Updated Arduino based PCB for 2024!
• High reliability, jam-free design. Thoroughly tested.
• Compatible with most Rival ammo including 3rd party ammo, and cheap knock-off rounds. Rock hard head-shot ammo not recommended
• High power custom designed brushless blower with 40 mm/H2o of static pressure. Enough to feed your blaster 4+ feet vertically
• 3s Jupiter, Juno and Rival blaster compatible
• Simple circuit, easy to install! Simply plug the pack’s XT-60 cable into your blasters XT60 plug.

SPECS:
• 20+ rounds/sec continuous ball feed
• 30+ rounds/sec ‘burst‘ feed rate for first 50-60 shots (Note, fire rate is ultimately determined and limited by your blaster).
• Printed in PLA filament
• Battery tray dimensions: 137 x 49 x 25 (LxWxH)
• Dimensions of hopper unit without container: 8″ X 4.75″ x 4.5″ (LxWxH)

TO COMPLETE THIS MOD YOU WILL NEED:
• Rival compatible blaster re-wired with an XT-60 connector
• Hose adapter to your blaster (sold separately or optionally on this page)
• 3s Lipo Battery. We HIGHLY recommend the high quality 2700mAh pack that is listed ONLY on this listing. We will make other options available as we get them in. The Turnigy 1500mAh 35-70c pack is also compatible.
• Soldering iron, solder and basic tools (for DIY-KIT version)
• A relatively airtight container, bucket, etc. You can purchase the 1-gallon container on this listing. 

COMMON QUESTIONS:
DUEL WIELDING: In order to duel wield the proton pack, you’ll need two independent packs and blasters. While I did test a single unit that could feed two systems, the fire rate was cut approximately in half, so I thought it best to use two units, rather than reduce the fire rate by 50%. We do not recommend modifying the hopper to attempt a duel-wield out of a single pack, as the airflow on the fan will not be high enough to feed two reliably.

AMMO: Most ‘Rival’ sized ammo types are compatible, ammo not included.  We do not recommend the new Headshot ammo or other rival rounds that are stiff.
