That should be correct. The only difference between the bodies appear to be that the “complete sets” (cars & controllers) of the MicroSizers have the windows painted black–like the OEM Bullets. I’m working on scoring a MicroSizer from Hobbico to evaluate and report on for The Admiral’s Lair, and according to their PR person, I should have one in late June. I’m trying to get ahold of a 49MHz car to make sure there’s no cross-talk with the 45 MHz (and just because I really want one :smiley4:).
Since Hobbico is planning on selling all of the hop-up parts, as well (engines, tires, gears, etc.), it’s highliy unlikely they’d do anything beyond changing the packaging. Everything should be cross-compatible.
