Nerf dart drop, individual release by servo (SG90)

This is a simple setup to carry and individually drop up to 12 Nerf darts using a SG90 servo.
Deflection to one servo side releases a dart from one shaft, centering the servo rearms the same shaft. Using the opposite servo direction discharges the opposite shaft - so ideally this is fitted to a 3-position switch.
May still need some fine tuning, as occasional blockage or double release hs occured during tests.
3 different fits provided for the matching the release wheely with your SG90 servo... check this thing to print a fit sample to find out which one matches your printer best:

Installation tip:
It fits the RC plane drop shaft of a Hype UCanFly, Hype UCanFly2, Hype WeCanFly, STModels Discovery or Robbe Charter NXG (all the same thing basically), and can be fitted e.g. with self-adhesive welcro.
Good for target practise, so next time you use the plane to drop sweets onto kids birthday parties, they won´t end up in the mud.
Note that it may be illegal to drop things from RC planes in your country.
