28mm diameter x 13mm wide silicone rubber wheels mounted 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.
Secure it to your motor shaft with the included 4-40 hex grub/setscrew (requires 0.050 hex wrench, like our HexW050).
