I bought a 60’s version of the helicopter and satellite cars. They seem to wind up ok… helicopter goes about four inches off the flatcar… the Satellite just spins! Is this normal? I don’t want to over tighten them, but you can tell they are winding up.
No it isn’t normal. The satellite should be flying into the celing if it’s right.
I dont have a helicopter launcher but i do have the Satellite car. When wound up tight the satellite hits the ceiling when I launch it from the floor. I’ve wound and launched over and over with no problems. Give it a few more winds than you have been and yours will take off to infinity and beyond.
