Based on the Fast Action Battler pictures from TF08.net, the actual name is Grindor whose alt mode is MH-53 Sikorsky Pave Low, the same alt mode as Blackout. The FAB line doesn't have enough detail to know if the character (and other toy classes) will have more differences then just the paint job. Thanks to Phil for the link.
FAB Bumblebee Bio
With the battle raging in the desert, Bumblebee knows he needs to be ready. He upgrades with the latest in deep desert weaponry and prepares to charge into battle across the dunes. The Decepticons will never know what hit them when they get a taste of his sand blast.FAB Grindor
Grindor is always ready for a fight. He plans everything out in detail, so that he knows exactly how a battle is going to go before it even begins. He is always at the center of the action so that he can use his heavy firepower to ensure his plans succeed.
