WL toys 12428 steering servo replacement and ESC recommendation

[Griffdog69]

I have been upgrading this WL 12428 rock crawler my son had. I am at the stage of replacing the steering servo with a 3 wire one vs the OEM 5 wire. I bought a futaba servo but it is too big to fit. I will figure a few other ways to make it fit but my next upgrade will be a receiver and esc. I already have a receiver by flysky and would like a recommendation for a new esc for it. I am keeping the OEM brushed motor in it so I don't need too much. Thank you in advance for any and all advice.

Thanks,

This is the car I am upgrading

going to need a radio receiver to use a 3 wire servo..can't recommend a servo as i dont know you trucks servo size
after looking at a few replacement servos Id say it is a standard 1/10 scale servo
