L9110H-bridge motor driver So I have this old RC car which doesn't seem to connect to the joystick very well so im going to modify it with an Uno with 433 MHz receiver/transmitter. 

Both the steer and drive motors work as intended so long as you can reverse their current. I've seen people use the dual channel drivers which is what I know I probably what I should use to drive the motors. I bought a starter kit a while back which came with a single L9110H Chip. I thought maybe I could order another one and just solder them to a PCB and mount the PCB along with the Uno inside the car that way I don't have an extra chip just collecting dust. I've looked at the data sheet for the L9110H and came up with a diagram on Fritzing. 



I was hoping someone could tell me if I'm on the right track with this?
Yes, looks good to me. That looks to be identical to the "Application Circuit" on page 2 of the datasheet you link to.
