another home made radio controlled unit from me..
again retaining my concept of only using a receiver and transmitter from a china rc car 1:24 scale, i designed and built this 1:18 scale crawler which has the capabilities of a factory made rc crawler...
no servo, shocks, differentials,etc.
all of it was home built and designed.
you can build your own too!!!!
































the answer is
1. design - use your ideas and skills, specially principles in physics.
2. draw what you designed from scratch.
3. built the prototype and test it.
that's how i made it
