– Variable rate of fire. Default configuration fires about 1 mag per half-second or 30 darts per second

    WOW!! This thing is AMAZING! I giggle every time I dump a mag! Shoutout to Frontline Foam for making this kit very easy to use with clear step by step videos and fast responses to emails with questions. The parts are all quality and mesh with the 3D printed files seamlessly. I appreciate Frontline offers multiple options not only for this kit, but options for different levels which is a huge plus if I can print my own parts. Huge win for the consumer and much appreciation for the company. I highly recommend the Lepus for all as this thing is solid, insanely fast, and so much fun!

    my dad bought it for me for my birthday we built had fun for a bit until we needed to rewire link my dad broke the button and we need a new battery although we think it is really fun

    What a fun blaster to use!
    I bought the hardware kit and printed the blaster myself on my Prusa Mk3S+ in Silk Yellow and Black using the files from this site.
    This was my first completely printed blaster and it was a super easy build. I do have a lot of fabrication experience but the Frontline Foam Youtube build guide was an excellent resource to build along to. With the 1200rpm motor it is a great dart hose but is still controllable enough to get 3 or 4 bursts out of a 15 round magazine.
    The small form factor and high rate of fire make this a great secondary or tertiary – or just use it to terrorize your friends, family, and coworkers!!

Which way/orientation should the switches be soldered in the video? I'm assuming the larger switch with higher amperage is the rev trigger and smaller one like in the video is the fire trigger. Should the rev trigger be on the right and fire trigger on the left (both with their buttons facing the left)? Also, at what lengths should I cut the red and black wires to without having too little? What should I do with the metal tips at the ends of each wire? Lucian asked on April 6, 2026

That is correct! The larger switch is the rev switch and the smaller switch the trigger/fire switch. Both buttons should face the left.

The lengths of wire should be 5" and 5.5" as per the guide. And the metal tips would be for the battery connector, so 8" for black and 5.5" for red.

Iam debating between the FoamBlast Fang ReVAMPed (130-2S) motor and the Out Of Darts Kraken motor (130-3S). My pusher motor would be running at 1500RPM, i was now wondering what the best motor would be? Also can i use a 3S lipo with 2S motors? Alexander asked on December 23, 2025

The Fang motors generally get better performance on the smaller wheel diameters. They are indeed usable with a 3s Lipo. However, if you rev for extended periods of time, they would heat up faster and could potentially burn out or wear out faster. However, under normal use, we haven't had any issues!

Can i use 2 smaller switches instead of one big and one small FIlip asked on November 14, 2025

Yea, that would work. However, the smaller switch may burn out and need replaced if the flywheels jam causing the motors to push too much current through the switch.

 Derrikk Sun answered on November 14, 2025 store manager

how much Amps are using all motors when they are not jammed

 FIlip answered on November 18, 2025

Usually a 7amp fuse works well! It depends on what motors are used.

-Derrikk

 Frontline Foam answered on September 25, 2026 store manager

Good question. Around 5 amps. It depends on temperature, wear and tear, etc. So 5 is safe, but 7 if a 5A fuse trips repeatedly.

what does mean the nose part 32.5mm FIlip asked on November 12, 2025

The 32.5mm refers to the distance between the flywheels!
