I folks!

I thought an update would be in order

Also shows my Arduino-based project to make a transmitter myself.

Lots of small things amounting to some progress:

Needed to crossdrill the wormwheel to prevent it from slipping.

Crossdrilled the motor shafts to install 2mm pins and standard 12mm hexes,
as the old grub-screw hexes proved unreliable.
Then tapped the motor shafts (internal M3) to mount the wheels, as the old fixture
with a grub screw collar was really bad.


Modified the Slash wheels:


Modified the front and especially the rear implement mechanism:


Modified the hood/bonnet


Added mechanical floating positions for both circle lifts:

complete with new switches on my joysticks

(The red switch is the dual rate, which gives me two driving speeds.)

Improved the articulation joint with thrust bearings

Currently I am working to get my driven front axle going, it's looking promising:
