Rear Tire Mount for 2 Rotopax Canisters (My original design)
Rotopax Mount Handle (My original design)
Assembly:
Glue is needed to attach the canister cap to the canister. I recommend waterproof Gorilla Glue (Affiliate link).
Rotopax can be glued to the tire mount. This is the way I'm currently running this setup on my 10lb rig that does roll on wheeling trips a fair bit but the canisters never broke thus far. However, there are screw holes available for M3 bolts as well.
Tire carrier is designed to mount on the standard 1.9 tire that comes with SCX 10.3. It may look like its too small but just squeeze the tire a bit when mounting. If, however, you do not like the look, you can scale the mount up a percent or two.
The mount handle is just for scale look, I have mine friction fitted but you can also opt to glue it.
