I continue my mission to motorize the Creator Expert fleet, have already done a bunch other of them.
I always try to make the motorization as inivisible as possible, you should not be able to see any electronics without looking very carefully.
As the Porsche is pretty big and heavy I used ad Buwizz and a Large motor geared up 20/12 to give it the power that a Porsche deserves. If you do not need Turbo Power it could also be powered with a cheaper CaDa system.
Since the PF servo is so big and bulky, i have used an M motor with a rubberband return to center function instead.
Also added 2 pairs of Power Function lights, altough I am not totally happy with the front lights, but this was the best I could come up with.
Because I am creating instructions for other to build this, I have not used any rare/expensive bricks and tried to reuse as many bricks as possible in new locations. It only requires about 150 extra bricks and electric parts.
If there are interest, I might create Power Functions and/or Powered Up versions later. I have some ideas to hide the IR reciever and there is still space for a slightly larger battery and motor.
