|That weapon could go on either vehicle, |
I just thought it worked best on the jet.
The Duocons are transformed by fitting the air vehicle on top of the ground vehicle by lining up slots and tabs, pressing the two together should then cause the toy to pop up into its combined robot mode. The result is a robot without discernible feet (not unlike the "Minibots" of a couple of years previously) and arms that cannot even be raised to point the included weapon forward. Flywheels actually fares slightly better here than fellow Duocon Battletrap. You can raise Flywheels' arms slightly to the sides. Battletrap's arms have no mobility whatsoever.
While it's never been proven, it's probable that the names of Battletrap and Flywheels were actually swapped at some point during the production process. Flywheels actually has no wheels on either of its vehicle components, and the tank is a far more "battle"-ready vehicle than Battletrap's camper-truck ground component (while I might say the same about Flywheel's jet versus Battletrap's helicopter, that's far less of a slam dunk, as the Apache has been used by the military for many, many years). It would hardly be the first time such a swap has been shown to have happened with two generally-similar Transformers toys.
