Top Spin was a "Jumpstarter" from the old G1 line, which meant that his transform was basically to fold him in half. Silly basic figure that he was, he (and Twin Twist) were always 2 of my favorites. When I saw Shinobitron's version that he posted a while back I knew I had to "borrow" the recipe.

I did a little different version for the detail on the head, using a modified Astrotrain noggin. And I left the original arms since I really liked the way they held the blades, it offered a lot of posability, and if you leave the blades in, you can fold them back to get a good resemblance to his G1 arms.

Finished off with an autobot symbol from reprolabels.

This guy proudly sits with my TF Classics Collection.

From the original Tech Spec:
No mountain high enough, no river wide enough to stop this one robot wrecking crew. Has superior mobility due to his Cybertronic vehicular form. Views conquest of rough terrain as much a victory as beating Decepticons. Uses 2 rear jet engines to go 300mph... goes 80mph on water with 2 front pontoons... has 2 hi-voltage electric cannons and 2 hand lasers built in... carries a powerful twin ion impulse blaster.
