Diaclone commercial

Yup. That was inconsistent. Ironhide and Bluestreak were shown flying in an early episode. The Dinobots all flew in robot mode.
Sideswipe loaned his rocket pack to Prime in the last scene of 'More than Meets the Eye.' Prime was shot down.

The story I understand is: The diaclones were human sized robots that piloted larger mecha. The would be Autobots were the 'Car Robot' line of Diaclone toys. So Convoy (Later Optimus Prime) is a large Car Robot with a lunar trailer meant to store other Car Robot mecha.
Convoy would later be upgraded with a new trailer that doubled as power armor and able to haul even more Car Robot Mecha into battle (Ultra Magnus).

The car robots were the mecha armor, not the actual diaclone pilots.

interesting that in japan, they had an English name, yet Hasbro changed the name, go figure, guess they thought "Transformers" sounded better.

I don't think the name 'Diaclone' would be a very motivating selling point for the toys. People would be asking 'What's a Diaclone'? While a Transformer is a LOT easier to explain, hence the name change.

It does sound better...

You can actually find some of these commercials as extras and easter eggs on the 20th Anniversary 2 disc special edition version of Transformers: The Movie.

They do on one of them.

one of these trucks is not like the other one of theses trucks is not the same.
