That could very well mean that the current version 1.07 (sticker on bottom of Typhoon) is The latest version and those units are shipping with Black motors.
Now, the bigger question here would be, what is the difference other than color? Improved motors?
Thanks BEE for that Clarification.
There is a difference. I just recently bought 6 from Best Buy(Colorado). They had two in stock and hade to ship to 4 to home. The 2 I brought home had black motors and the other 4 had silver motors(all 4 were shipped from Ohio). The difference is what is inside the packing. Black motors came with:
Black battery w/charger
Black rotor blades
ST10+ Transmitter w/shield
16GB microSD(even though the packing list says 8GB)
CGO Steady Grip
Typhoon RTF Airframe
Now the other 4 were a little bit different. They were the same except for:
I've hade a few pilot mishaps with the first 2 I purchased (black motors), and the replacement blades I purchased were white. So far there has been zero difference in flight stability and control. The replacement motor/ESC controller I purchased was a silver motor and yet the same results, zero difference in flight stability and control. So far there has been no difference in flight stability and control between the 6 Q500 4k drones that I purchased. Also all firmware was current with 1.07 version for all drones.
