If you thought solid axles were strictly for trail and
monster trucks, think again. Tamiya’s Grasshopper
and Hornet dynamic duo (as well as countless clones
of those designs) all rolled out on solid rear axles that
incorporated the motor and transmission as a unit. What
the floating-pod concept sacrifices in performance
to independent suspension it recovers in reduced
complexity and parts count—and thousands of RC’ers
getting started in the ’80s thought it was just fine.
380 BRUSHED POWER
Just like it did in 1988, the Grasshopper gets a 380 brushed motor
instead of the usual 540 size. We’re not talking a lot of power here. But
you can install a 540 if you want to; the 380 mounts to an adapter plate
that simulates the hole spacing of a 540 motor, so boosting power is
easy. One thing the Grasshopper definitely didn’t have in 1988 was an
electronic speed control, but Tamiya throws one into the box for you in
2017. It’s not a big-amp unit ( Tamiya says it’s for stock motors only), but
a stock motor is plenty for the lightweight Grasshopper. And you can
even go brushless— Tamiya says 25. 5 turns is the motor limit, but good
luck finding one of those. A 21. 5 T should be fine.
