Tried to use my huge Canyon tires whit the geode wheels but i kept killing the pins on the center driveshaft... They are just to heavy, but they really makes a good scale and hooks up great. And they have great gyro:
Used traxxas 17mm hexes for the Slash to mount them. Drilled to 8mm:
Found some new descent 23mm wheels! Thundertiger makes some!:
Bought some Panther paddles:
Didnīt really like how the Pantherīs hooked up in the rear so I bought some Proline 3.2 paddles and mounted on some old 40series 23mm Proline rims, had to cut them quite a bit

Got some Rpm arms finally:
