Castle Phoenix 45 amp HV bl esc (Box 76)

Don't let the amp rating fool you here - 45 amps and 50 volts adds up to over 2,000 watts of power! The Phoenix HV45's compact size and light weight make high voltage systems a realistic possibility for even small field rc aircraft and small to medium sized rc helicopters. Use the Phoenix HV-45 ESC in your next 0.40 size electric rc conversion and marvel at the extra power and runtime that high voltage systems are known for. Do you like large rc aircraft? We powered our own 11lb Funtana 90s "test" aircraft with a Phoenix HV-45 controller and a 12s Lipo battery pack for unlimited verticals and wild 3D maneuvers - electric rc flying has never been this fun as well as affordable!

Optocoupling prevents the Castle Link from powering the electronic speed controller (ESC). The ESC will pretend to be dead if you simply connect it to a Castle Link. To program an HV ESC, you need to power the ESC through the battery power lines.
