Title: Trying to understand ESC, brushless motor, Transmitter and Receiver.
Post by: sim_tcr on January 15, 2018, 09:20:32 PM
Hello,

I am new to RC hobby.
I am trying to understand ESC (electronic speed controller), brush less motor, Transmitter and Receiver by connecting all these components.
My main goal is to achieve progressive throttle/steering.
I am planning to buy https://www.ebay.in/itm/A2212-1400KV-Brushless-Motor-30A-ESC-1045-Propeller-Set-Multirotor-Quadcopter/331661007308?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649  and https://www.ebay.in/itm/2-4G-3CH-Digital-Remote-Control-Transmitter-with-Receiver-for-RC-Car-Boat/222755613558?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649 and use my own 1.2V 2800mAh NiMH rechargeable batteries to power these.
Can some one confirm all above will be compatible each other and achieve my goal?

If this is not the right place, please move it accordingly.

Thanks.

could you please explain bit more, so that I pick the right one?
I was reading more (after my original post) and what I understood is,
Throttle/speed is from brushless motor through ESC. And throttle channel of receiver is connected to the ESC.
Steering is from servo motor which is connected directly to steering channel of receiver.
Is that correct?
if so, the mentioned transmitter/receiver has 3 channels which i can use for above purpose?

Thanks

Sorry I didnt read it carefully at first, you are talking about RC Car,  then the TX RX is compatible.  I was thinking about plane.  BTW I have not idea about RC Cars.

•You need an inrunner brushed/brushless motor.
•TX and RX are fine.
• An appropriate battery(NiMH, LiPo, Lion) is required which can be decided after choosing the motor.

30A Electronic Speed Control (ESC)
Description - Electronic Speed Controller (ESC) is a electronic circuit to vary the speed, direction and possible to act as a dynamic brake,  of a Brusless Motor. This particular ESC is recommended with A2212 brushless motor (1000kv, 1400kv,2200kv).

Specifications -

Weight : 23g
Dimensions: 45.0*24.0*9.0mm
Current(A): 30-40
BEC : 3A
PWM: N/A
Li-Po : 2-3
Ni-Mh/Ni-cd : 4-10Ni-Mh
Constant current : 30A Max 40A <10s
Li-Poly 2-3 cells;  Ni-MH 4-10 cells Auto Detect
Break On/Off
Auto Low battery Slow down at 3.0V/cell Lipo, cut-off at 2.9V/cell Lipo

I am planning to use 6v Nimh as the low battery is at 3v.
You think above motor is good? This is not for any drone or plane. For now just to learn things may be if all goes well I will use it build a small rc car.

Better to buy a car to start with

The parts you are looking are would never work in a car.
They're for rc planes or quads.

If you want to get into cars, I have a car for sale. 1:10 scale 4wd, brushless.
With spares and a lipo battery, 13k+ ship
