act as a template for the drilled pilot holes. Just
remember to drill and fit one screw before drilling the
other three. That helps to make sure they are all
correctly aligned. I added Dave’s Hubs and 2. 25”
Lite Flite wheels to complete the motor assemblies
The chassis uses Kitbots mini nutstrip to hold it
together, and I rough-cut the sections on my small
miter saw (Figure 13), then filed the ends smooth.
The chassis is then assembled using 6-32 screws.
With the top panel fitted to keep it square (Figure 14),
the bottom panel can then be added. It is secured by
placing 12 #6 self-tapping screws into the drilled pilot
holes (Figure 15). Line up the panel and insert a
couple of the screws before drilling and inserting
More #6 self-tapping screws are used to secure the
four motor assemblies (Figure 16); refitting the top
panel (Figure 17) completes the rolling chassis.
The final part of this series will cover the installation
of the electronics and setting up the radio transmitter
and receiver. SV
