The HobbyKing Red Brick ESCs wont win first place for style, though they will take top points for simplicity and reliability. With a basic set of programming features these ESCs are a perfect solution for anyone looking for a basic yet robust speed controller.
Specs. Max Amps: 50A Ubec: Nil Cells: 2~7s Lipoly Size: 60mm x 14mm 35mm Weight: 40g (Inc Wires)
It means that unlike other ESC's this ESC does not supply power to the receiver/servo circuit as it does not have a BEC (Battery Elimination Circuit). You will need a receiver battery pack or an extra BEC circuit like "6V 3A UBEC 2-5S Lipoly (6-23v)" PRODUCT ID: UBEC6v3a or "TURNIGY 3A UBEC w/ Noise Reduction" PRODUCT ID: TR-UBEC or "5V 5A UBEC 2-5S Lipoly (7.2-21v)" PRODUCT ID: X5UBEC or "Turnigy 5A (8-26v) SBEC for Lipo" PRODUCT ID: SBEC-26V or "HobbyKing Micro UBEC 3A / 5v" PRODUCT ID: HK-3EC01 or a 4.8V~6.0V battery pack from "Batteries & Accessories > Rx/Tx Batteries" or another ESC "HobbyKing Red Brick 50A ESC" PRODUCT ID: RB50-ESC which has a BEC built in.
11-23-2011, installed in a Horizon T-28 with a Power 10 motor, and Castle 10A UBEC. Power is from three new, charged, 3S, 20C, 2200 Zippy batteries. Works just "OK"; the Red Brick 50A shuts down immediately on some batteries and not others. The problem is IT IS VERY DIFFICULT TO CHECK THE DEFAULT SETTINGS IN THE ESC. It is VERY hard to interpret programming steps in the one page of instuctions. These need to be rewritten.
