Castle Creations COBRA 5 Product Use Manual

Designed for use in 1/7th and 1/5th scale RC vehicles. The Cobra 5 is not intended for drag racing applications
and the one-year warranty does not cover the use of the system outside if its intended use. Drag and speed run
setups are inherently abusive and exceedingly hard on all electronic components. Every component in the
configuration can be strained, weakened or worse without extreme caution. High speed runs and drag racing are
the most aggressive and volatile applications in the RC car hobby. Improper setup or use of this product can
result in catastrophic failures of the motor, esc and/or batteries. For this reason, Castle does not warranty
products used in these abusive applications.
•
Individual transmitter signals for neutral, full throttle, and full brake vary, so you must calibrate your Castle
ESC so that it will operate effectively with your transmitter.
•
Anytime the ESC is powered up with a new transmitter or with different throttle channel settings, it will need
to be calibrated to the transmitter's throttle settings.
•
Additionally, we recommend that the ESC be calibrated after updating to new software via Castle Link.
•
Applying voltages higher than 33.6V will cause irreparable damage to your Cobra 5 controller.
•
8S HV LIPO PACKS CHARGED TO ABOVE 33.6V (4.2V/CELL) CANNOT BE USED.
•
The Cobra 5 is a high-performance controller; you must use high-discharge cells in your high-performance
application to ensure vehicle performance.
•
MINIMUM battery capacity is 5000mAh and MINIMUM of 50C continuous for general use; for more
aggressive setup setups we recommend a MINIMUM of 70C continuous, discharge LiPo batteries. You can
never have too high of a C rating or too much mAh; more is always better
•
If the batteries you are using contain input bullets you might consider upgrading to a direct wired pack as the
bullets may not be able to handle the currents that the Cobra 5 ESC can push out.
•
If you must disable low voltage cutoff to prevent the ESC from shutting down, then your batteries are
insufficient for your application. 3.2v/cell is the lowest a LiPo battery should ever be discharged under load.
•
Utilize the data logging capability of the ESC to verify your batteries are not dropping below the cutoff voltage.
Exceeding a LiPo batteries capabilities can lead to a catastrophic failure of the battery and/or esc.
We have tested these batteries/brands in extreme setups (see connector ratings minimum section to
ensure your battery connectors are appropriate) and recommend them for the Cobra 5:
