και το δευτερο


Red Brick 70A Brushless ESC With 5V 5A UBEC for Helicopter Airplane Quadcopter
Features:

The Red Brick Series of ESC's don't win prizes for looks but their simplicity and realiability
They have a basic set of programming features but to be honest, looking through the manual there is not much that you can't program .they provide the perfect solution for anybody wanting a basic and yet very robust speed controller.
The Red Brick ESCs have been engineered with heat dissipation in mind. As a result, they feature an over sized Aluminium heat sink and therefore, are slightly larger than many ESCs in their class, however this compromise in size is aimed at assisting to eliminate the problems associated with over heating.
The reality is about 14g difference give or take and remember, this ESC includes your BEC whereas many otheres don't.
If you are not comfortable using the in built BEC, remember you can use a separate one. Just remember to cut and make safe the red wire on the built in BEC to ensure that only the signal moves and not the volts.
Max Amps: 70A
Ubec: 5v / 5A
Cells: 2~7s Lipoly
Size: 75mm x 20mm 39mm
Weight: 77g (Inc Wires)

Important Note: this ESC is Opto, without BEC supplying power to your Receiver, you need extra power source for your receiver. You can use a UBEC, a voltage regulator, or extra batteries as the power source for your receiver. If you hear the music tone repeat again and again for more than 3 times, you may need to check your power source to the receiver.
