Electronics help (Tx Rx servos...)

I am looking to make a rc gas powered power wheel. I have a 49cc engine and a power wheel jeep. I need help choosing what I will use for a controller, receiver, and servos.

I will need a servo for the gas and brake. The gas could be controlled by a simple rc car servo because it wouldnt need much force to actuate the carb. However, the brake I will be using is a disk brake with a caliper. To move the caliper arm would need about 5flb.

The steering will need a high powered servo due to the weight of the car.

Now is where you guys come in! Please could you suggest all that I would need to make this possible? I am new to this and have an idea but dont know where to go from here. I would like to learn everything. So I need a radio, receiver, a (small) battery for a power source then servos but I dont know how to tie it all together!

Thanks for your help!

The Sabertooth 2x12 RC is one of the easier RC controlled DC motor controllers to understand. You simply plug inthe leads like a normal servo, connect the battery and the motors and you’re essentially good to go. You’ll notice the Sabertooth 2x12 is essentially the same controller but without the pair of 3-pin leads (so you can solder your own). There’s a diagram at the end of the datasheet which shows you how to connect everything.

To confirm - you want to convert the power wheels Jeep to gas power and make it remotely controlled and to adapt the gas and brake to use servos? Also, rather than using the brake pedal, you want to directly control the disk brakes? Note that you can plug servos directly to an R/C receiver (no additional electronics required). However, if the servos are powerful, you might want to feed them separately and only connect the signal and ground (split) cables.

Certainly - you’ll need an RC controlled DC motor controller. Some of them come with R/C leads, though if not, you can purchase them separately. Note that almost none of them use position (via potentiometer rather than encoder), so you’d only control the speed and direction of the motor. We do offer some high power RC servos.

Okay I have an idea of what you are saying… Is there anyway you could give me links and a list so I can research what all I need and how they are connected? I don’t know anything about motor controllers or how they are connected to the tx and rx.

Yes. I do not think a standard rc car servo will have enough power to move the steering or operate the cable for disk brakes. Ideal I would need a high powered servo to operate the steering like a windshield wiper motor or something simpler (why I am asking). Then im not sure is there a way to connect a high powered servo and a normal servo to the same ch on the controller that way I could connect the high powered one to the brake and the standard rc car servo to the throttle?
