So last September, my wife and I welcomed a little boy into this world. Before Jake was born, Wal-mart started selling battery powered VW buses. I ordered mine online and shipped to store and it showed up the day we were scheduled to go in for induction.
This is the bus: http://www.walmart.com/ip/RollPlay-6V-VW-Bus/45717570
This build thread took a two day pause while acquiring a driver. On the way home from the hospital, we had to stop by my job site for work because we had some marketing photo shoot, so the first house we took my son to, wasn't actually ours...
The first night that he was home, I began the transformation!
I did a similar conversion about 3 or 4 years ago when my sister (TrooperChris's wife) asked me to make a power wheels jeep remote control for their infant. Like a good uncle, I obliged! Then he grew up and a family friend asked for the conversion on theirs so I swapped it all over and they haven't given me back the RC equipment, so I started on Jake's setup.
I sourced the appropriate equipment:
1- 45 amp ESC for brushed motor ($11)
1- 2.4ghz 3 channel remote controller and receiver (~$20)
1- 1/4 scale servo for steering (Hitec HS-805BB)
Various connectors, plugs, Y-harness, etc
I made a bracket for the steering servo to mount on. The bracket secures the body of the servo to the front axle. Then I use an RC car tie rod to connect between the servo and the bus's tie rod. These 1/4 scale servos are really strong. This one boasts 343 oz/inch of torque at 6 volts. I had to run a power wire from the battery to the servo so that it was getting the full 6 volts instead of having to pull its juice through the pins on the receiver. This is where the Y-harness and extensions came in.In the end, this let me take control of the steering.
Then I cut the wires between the stock battery on the bus and the stock motor. I use Deans connectors on a lot of my RC equipment, so I continued with those and installed the speed controller between the two. The ESC, when plugged into the receiver, acts like the accelerator pedal and lets me ease on the throttle from the remote.
I installed the receiver and hooked it all up. Bingo!
