This blaster was a lot of fun to build, took me about a week roughly 1-2 hours nightly. It's running on 3S, 3D printed cage 41.5mm, Daybreak flywheels, Titan/rapidstrike pusher with Valkerie motor, running a MOSFET on the pusher motor to control the speed. I built in the lipo battery into the unit but it can easily be taken out if needed. It has Valkerie motors but thinking of changing them to Fangs or Krakens as on full auto power I feel the flywheels steady but can shoot faster.
