Castle COBRA 5 HV 12S ESC With 2028-800KV Motor

TAKE YOUR TRUCK TO THE EXTREME WITH 12S CASTLE POWER!

COBRA 5 HV ESC- HIGH VOLTAGE. NO COMPROMISE

The Castle Cobra 5 HV takes everything  the Cobra 5 has and dials it up to 12. With 50.4V support (12S LiPo) this ESC is built to tame 1:4 scale monsters weighing up to 50 lbs.

COBRA 5 HV FEATURES:

• 32-Bit processing power for smoother motor control and improved response time.
• Enhanced Data Logging includes:
• Double the maximum sample frequency of older generations.
• 8x increased logging time of older generations.
• ESC electrical motor timing data.
• Acceleration data via onboard accelerometer.
• Looping feature prevents interruptions in data log recording.
• Additional tuning features include:
• Improved braking adjustability
• Separate brake and reverse curves
• Highly adjustable internal BEC (5.0V - 8.5V adjustable in 0.1V increments)
• Access to tuning options and firmware updates for free with Castle Link V4 USB programmer included with purchase.
• Upgraded current-sensing and thermal protection system actively mitigates the risk of failure in aggressive or high-load setups. 

ADDITIONAL FEATURES:

• CRYO-DRIVE™ Technology minimizes the amount of time the ESC’s electrical components spend generating heat, resulting in improved thermal performance during partial throttle operation where the majority of driving occurs
• ESC is housed in a rugged CNC aluminum case and potted in waterproof epoxy to protect the electronics and promote efficient heat transfer
• Premium forged heatsink with elliptical fins for superior air flow and increased heat dissipation
• Oversized factory equipped thermally controlled 50mm cooling fan
• Waterproof design for all weather conditions
• Auxiliary wire functionality for "on-the-fly" adjustments using your transmitter
• Audible alerts for easy diagnosis of common issues such as motor-over-temperature and low-voltage cutoff
• Convenient transmitter programming for six common adjustable settings including cutoff voltage and drag brake

Motor:

The Castle 2028 Extreme 800KV motor now has an IMPROVED 4-POLE 12-SLOT design that boasts exceptional EFFICIENCY and produces LESS HEAT.  If you need LARGE-SCALE POWER for LARGE-SCALE VEHICLES the new BRUSHLESS SENSORED 2028-800KV motor will no doubt hold up to the heavy throttle and extended usage that 1/5th scale vehicles like the Losi 5IVE-T, 5IVE-B or DBXL-E encounter. It is the perfect upgrade for any 1:5 scale RC hobby vehicles (including gas to electric conversions) weighing up to 30 lbs for 2WD and 25 lbs. for 4WD.  The 2028 Extreme can easily run in the 10 horsepower range*          

*Burst power output for durations typical of vehicle acceleration. FEATURES:

• Running modes include Sensored and an ULTRA-EFFICIENT sensorless mode.
• High-strength, high-temperature grade neodymium sintered magnets combined with High-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions.
• Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible.
• Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor.
• Dual sensor ports to ensure optimal installation in your large-scale vehicle.
• Updated modern and sleek design; looks as cool as it performs.

Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it, resulting in a cooler running motor. A cooler motor has a longer lifetime. Construction of our motor required careful component selection; each verified through internal testing to ensure the HIGHEST EFFICIENCY possible. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn’t put our name on anything less.
