28 x 13mm Traction Wheel assembly on Aluminum hub

Note: We recently have seen a surge of interest in these from readers of "Popular Mechanics" online article "How to make the Perfect Paper Airplane And a DIY plane launcher to go with it". We are now sold out of this style of wheel, but you can substitute the bigger brother "RW38 with 2mm hole"; just make the holes 1-3/16" (30.5mm) apart. Additionally, we can streamline your build - you can get the wire, switch/battery pack here too!

This is our replacement for the old RW wheel, which is (alas) no more. We'v re-created it with the same style machined aluminum hub with set-screw mounting.

Specifications:

• Tire:
  • 28mm (1.5") diameter,
  • 13mm (0.5") wide
  • 12.7g (0.45 ounces)
  • 20D durometer
• Hub:
  • Aluminum constructions
  • 12.7mm wide
  • 2 or 3mm shaft hole options

Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).
