HELP needed 4 the World's Largest mass produced R/c car...

[RCpickens]

Hello Everyone,

I recently purchased a 1/3 scale RC atv, made by 3Z Scale and it was called a Bulldog R/C Rider.
It was made in 2009 roughly. It has a gas engine.

Here is a link to the specs:​

Here is a link to a video of it in action:

ISSUE:
It requires a passcode to access the r/c electronic, of which i don't have.

Can anyone help with this, i.e. how to bypass the passcode system, maybe rewire to use newer electronics, but with the old servos, i dunno...

ANY help would be appreciated.

Thank you,
RCpickens

Did you try the same code sequence shown in the video?

Thank you, AND I can now say, YES to that question. Nice try thou, never thought of it. But, no luck... Any other advice would be Greatly Appreciated. Thanks again.

Hello, did you find a way to get your rc truck running?

 

[RCpickens]

No, I think i would like to start from scratch. I am removing all electronics , leaving steering drive motor (12vdc), and installing a electric motor with controller. Does anyone have a suggestion for updated electronics. Possibly a Arduino based control. Open for ideas. Arduino rc control? Appreciate any help.

the problem with arduino controls is gonna be finding and esc being enough to power the motor your gonna need ... as far as setting up the pwm signal that wouldn't be too hard ... could probably use a nano for that instead of a uno ... the other problem is going to be regulating the arduino power ... and making sure your servo/ esc doesn't over pull on the arduino pins

Appreciate the Reply.
Additionally, a lil more detail; I installed a 96volt ATV electric motor conversion kit. It came with the batteries, drive motor, and controller. The controller is controlled by a thumb action (i believe) controller that mounts to the handlebar. low voltage control.

My thoughts were if i could replace the thumb control for speed with a RC servo or possibly a Arduino to control the speed/juice to the motor. The 12 vdc ( i believe since the battery for the old drive mechanism was 12volt) steering motor is about 2 inches in diameter and 3 inches long, no identification on it. It controls the steering at the gearbox for the steering mechanism.

I will get some pics and the instructions/specs for the controller outputs/inputs.

Appreciate any help, Sincerely, Thank you

Hey were you able to get yours running?
do you still have the original electronics? I would be willing to buy the parts off you if you still have it.

Also for your issue i would just physically connect an rc servo to your thumb throttle. I would just 3D print a simple housing and mechanically attach the servo to your throttle potentiometer.
Also for steering get a dimensions engineering 2x12 sabertooth and Kangaroo. Both of these will create a close loop system so that you can create your own servo.
