I've bought PF servo motor about one year ago and I haven't got chance to test it. Then this ugly buggy 42037 appeared and I realized it's good volunteer for testing it. My goal was to make it fully remote controlled with adding just PF parts and keeping original look as much as possible. So after two days I've got this result.
It's powered by one M-motor, steered by servo motor and even uglier than before. It rides well on smooth and solid surfaces but it's pretty slow on carpet. Main issue was to find room for battery box. Front of buggy is almost unchanged and rear is rebuilt much. It can still open cab and fake engine works. It lost just seat and lights. If anyone is interested I'll share its LDD file.
