Hi all!

I'm starting up this thread as I begin work towards my new featherweight, Shuriken. Since this is my first time building a spinner, I thought it best to try it in FW scale first as a proof of concept, so I can ultimately work my way up to a heavyweight version, Samurai.

Despite this being a new thread, I have been planning and tweaking this design for a while. Having followed a few other threads, I think I have some basic aspects and a general layout clear in my mind.

  • HDPE chassis (20mm sides, 8mm top/base, reinforced with aluminium in key areas)
  • Drivetrain: 2x Gimson GR-EP-45 gearmotors
  • Weapon: 500 x 60 x 15mm Hardox 500 spinning bar, weight 3.6kg, angled forward approx. 25 degrees
  • Weapon motor: Turnigy Rotomax 50cc brushless
  • Power source: 1x 4000mah 4s lipo for drive, 2x 5000mah 5s lipos in series for weapon


This is going to take a while, certainly I won't start buying parts until the end of summer, but at least by then I should have a finalised design. If anyone has any advice to offer, feel free. I need as much help as I can get!
