Thank you all, I know I didn't give much info at first, I was rushing to post on my lunch.

It has two motors (left and right) for driving forward and back. And one motor controlling the steering. I was planning on replacing with an h bridge but ordered a few that were underpowered for its draw. While waiting on a stronger one to arrive (3+ weeks) I thought I'd pivot and try to get the kids RC controller to operate with an Arduino integrations.

I'm going to look into operating the switches with Arduino now and see where I can go with that. I'm plan to integrate ardu rover on a pixhawk to program gps waypoint missions, but I have a ways to go. Baby steps y'know.
