Here is the box along with my original build electronics setup.
Oddly, I chose a lovely Hobbywing brushless sensored motor and ESC combo
and then paired it with the cheapest servo I could find. I guess I
figured the load requirements were low. It actually works
fine. I'll replace it some day when it dies. Super fast
speed is not important to me because I don't race.
I only took this single photo during assembly and then I became too
engrossed and built the whole thing in one night. This shows part
of the first ball diff I ever assembled. I screwed it up.
When clamping it down, I forgot to put in the spring first which
resulted in crushing the plastic nut holder inside the hub. The
whole thing was a nightmare and I stayed up all night correcting
it. I did manage to fix it without buying any more parts though,
and I've driven the car for months with no problems.
This shows the front and rear suspension. The front suspension
uses pushrods and crank arms to locate the shocks inboard and free up
space for low bodies. The system works pretty well with very
little lost motion. The front and rear suspension use the same
type of control arms. The rotation axis can be adjusted by
inserting different blocks for the pins. The upper arms are
turnbuckles which allow length adjustment for camber, and the rods can
also be attached at different positions. The battery compartment
is big enough for moderate Li-Po's.
The completed car. The chassis tub is pretty full once the ESC,
servo, and receiver are installed. The receiver actually sits on
top of the servo. I cut the wires short and soldered them directly
to the motor to avoid clutter and I like the way it looks. The
whole system is very quiet on the road, with the loudest noise being the
hum from the sensor system. From the bottom you can see the
smooth surface with the cooling duct for the motor and slots for the
battery.
