2 x Phoenix Ice 100 AMP ESC 34Volt up to 8S plus Castle Link device and USB cable. Please note the red wire of the servo cable on both units has been cut. I never have trusted a UBEC on a high voltage system and used a separate receiver battery. If this is a problem I can rewire a new plug. Both ESC have been tested with a 5S battery and 5055 motor. The units have not been tested with a prop on high load. ESC's $110.00 each, Castle link $30.00. Or take all three items for $230.00 Add 4% for paypal.
