capacitors, receiver connector, and red and black wire side). The red wire is the positive (+) lead, and must match up to the positive lead from your battery. The black wire is the negative (-) lead, and must match up to the negative lead from your battery. The polarity MUST BE CORRECT or the controller will be damaged from reversed polarity. The Hydra 240 has two SETS of input and output wires. We recommend using a separate connector for each connection to ensure maximum current capacity. Make sure and connect the entire battery pack to both input wire sets of the Hydra 240. Do not connect half of the pack to one input, this will lead to operating problems from potential voltage / current imbalances.

Disconnect battery Programming the HYDRA™ is as simple as answering a few questions. The Hold full throttle on your transmitter HYDRA™ asks questions by flashing a setting number, followed by the possible setting values. There are five settings that can be programmed in the HYDRA™: HYDRA™ flashes LED and rings once 1) Reverse Type, 2) Reverse Throttle Amount, HYDRA™ flashes LED and rings 4 times indicating that it is ready for 3) Cutoff Voltage, 4) Timing Advance, Continue to hold full throttle 5) Starting Power.

When you enter programming mode the controller will emit a HYDRA™ flashes LED while beeping indicating that you are in sequence of beeps and LED flashes that tell you which programming step you are in. There are two parts to the beep sequence. The first set of beeps indicates the Let trigger go neutral (center) ‘Setting' Number (e.g., Cutoff voltage type), and the second set of beeps indicates a Setting Value (e.g 2 cell LiPo). Answering "no" to a Setting Value will cause the At this point the HYDRA™ will be flashing/beeping the following sequence: HYDRA™ to ask for the next Value. Answering "yes" to a Setting Value will store Beep – Pause – Beep… and then Repeats that setting in the HYDRA's™ permanent memory.

remaining programming options at their previously stored values. 3.2.6 A Word About Cutoff Voltages
If you are running NiCad or NiMH cells, the default cutoff voltage of the HYDRA™
(5.0V) is normally what you should use, and anything else in the programming is up to your personal preference to change, so you are ready to run! ** IMPORTANT NOTE: Lithium Polymer Users **
If you are using Lithium Polymer (Li-Po) batteries, DO NOT operate your boat with the factory default Cutoff Voltage. You MUST change the Cutoff Voltage BEFORE running your boat.
4.0 Troubleshooting:
Everything is hooked up correctly, the BEC (receiver and servo) works, but
the throttle does not work.
The controller is not seeing the four seconds of neutral throttle and is not arming. Try moving your throttle trigger slightly in each direction to arm the controller or follow the calibrating function Section 3.1 above. You may also check to make sure that your endpoint adjustments on your radio (if it has them) are set all the way open (both top and bottom, are furthest from zero).
