I wanto buy the following ESC and BEC but I don't know is it compatible with each other. Can someone see it and let me know? I'm installing both of it on my Stock Belt-CP. I don't have a ferrite ring. I use 3S1P 11.1 2200mah 20c Lipo, Tower Pro sg90 servo. Which BEC you recommend for the ESC?


ESC
GWS Brushless ESC 35A 2-4S 3A BEC, Speed Controller.
Weight: 22g
BEC: 3A


BEC1
Spec.
Output: 5v/3A or 6v/3A (Selectable via jumper)
Noise: <50mVp-p(@2A/12v)
Input: 5.5v-23v (2-5S Lipo pack, 5-15cells NiMh)
Size: 41.6x16.6x7.0mm
Weight: 7.5g

Features:
Over current and over heat protection.
Switching frequency 300khz.
Chip Efficiency is 92%. This UBEC utilises switching technology to gain a much higher efficiency than liniar BEC. Which means less heat and longer battery life.
The UBEC is equiped with a noise reduction alloy housing to reduce noise even further.
Incorrect polarity safety feature ensures the UBEC will not be destroyed should the battery be connected incorrectly.

or BEC2
Spec.
Output (Constant): 5v/5A or 6v/5A
Input: 8v-42v (3-10cell lipo) High Voltage
Size: 48x27x9mm
Weight: 37g
Quiescent current: 20mA

Features:
Type: Switching, however because of the noise reduction (thin metal case & filter) this unit gives the same noise as a Linear BEC.
