The yellow guy is the Passenger, he does nothing but be a passenger. (might have been called a Dummy) The two propellers are the old ones, can be placed near things and used, but not adjustable. These parts cannot be gotten anymore but I had them in various places, and upon removal made them there own subassemble, a while ago, I released them, then realised I also had the other propeller in a subassemble and added it and am rereleasing it. I have none of the stats for the weight or power but atleast you can have these parts. I have looked through others ones of this cause other people put out old part downloads, but so far as I looked through like a dozenish of them, I found none with the old small propeller, and few had both the big propeller, and the dummy together.
