Have checked if the Redcat diff outputs can be turned down to 6mm shafts so that I would be able
to use the Redcat dogbones (or FLM balldrives). Well, unfortunately the pinhhole in the shaft is
at the wrong position and too big. Drilling a new one is not possible because it would interfere
with the old one. Not nice. Other ideas would be using a wheel axle and turn it down to 6mm, problem
with that is, that most (if not all) wheel axles are hollow so that won't work either. Another idea
would be to make some custom diff output shafts like the ones from RC-Monster but with 6mm diameter
inside the diff and 8mm outside, so that a diff input cup could be attached. Downside is, that this
will make everything wider, so one would have to mount the arms more outwards, also not easy.
For people who want to use Savage axles, I think there is a way to get it to work using stock Savage
axles and diff outputs with FLM extended 11mm dogbones. To fit the Savage axles in the Redcat hubs,
replace the 10x18 axle bearings (for the buggy, MT bearings are different size) with 8x18 bearings
(or use a spacer sleeve). To get the length correct, make custom hingepin braces with holes more to
the outside.
Since I don't want to use Savage axles anymore, the only easy (but not cheap) option I see would be:
Have some custom dogbones made that are a tad shorter than the Redcat ones and with 12mm ballend on
the axle side (for Redcat axle cups) and 11mm ballend on the oder side (for Savage diff output cups).
Got some 10mm axles and 24mm hexes from a Reely Carbonfighter 3 (also sold under "Smartech" label),
and test-fitted them. Looks like this would be a good option for people with Baja or XL size chassis
and 24mm wheels, it gives about one inch of extension per side.
