TurtleRC Turtle Brain Model B
Instruction Manual
V2.0
WARNINGS
Keep your hands off the control sticks when powering on the Brain or Transmitter.
Always use a functioning killswitch if someone will be riding on your prop.
PRACTICE driving your prop in a safe area away from people until you understand how it
moves and reacts.
CHANGELOG FOR MODEL B
Model B does away with the fuse and power switch present on Model A, and instead employs a 50A
thermal circuit breaker. This provides the same protection as Model A but does not require a supply of
50A fuses. If a stall or other fault occurs once and the breaker trips, simply reset the breaker to activate
power. If the breaker keeps tripping, something is causing an over current issue that needs to be
corrected.

    1. Motors and Wheels Acknowledging that our Turtle Brain is just that, a 'brain', we need to have something to control. In this case, the 'brain' is controlling 1 or 2 brushed DC motors. Most configurations will have 2 motors in a 'differential drive' format –...
  • Page 5 3. Something to Move Of course you didn't just buy a Turtle Brain to admire it (although we wouldn't blame you). You need to combine the Turtle with some kind of cool stage prop or item you want mobilized and remote controlled.
  • Page 6 Once you have your motors connected to the Pigtails, plug one of them into M1 and the other into M2. If you later determine that the Turtle isn't responding how you would expect (left and right or forward and back reversed) check the Troubleshooting section for how to correct the motor connections.

    Basic Usage Getting the Turtle up and running once it's set up the first time is straightforward. Step 1: Turn on the Transmitter after installing batteries (included) WARNING: DO NOT TOUCH THE CONTROL STICKS WHILE POWERING ON THE BRAIN OR THE TRANSMITTER. DOING SO MAY CAUSE SUDDEN UNCONTROLLED MOTION OF THE PROP.

    TRANSMITTER The Transmitter isn't making the motors move, even though the Red LED is on. In rare cases you may need to re-bind your Turtle Brain to it's transmitter. To do so, do the following: 1) Turn off everything. 2) Plug only the battery and killswitch into the Turtle Brain (LEAVE THE MOTORS UNPLUGGED).
  • Page 12 MOVEMENT Because there are so many ways to mount the motors to your props, you may end up having mismatched control of your prop at first. If your Prop doesn't react appropriately to the stick movements, follow the diagrams below to determine what you need to do to correct the situation. NOTE: Sometimes it may require more than one tweak to get your system working.
