4449pcs Cada C61053 Helios Supercar Apollo IE 1:8（Dynamic version）

I don't know, haven't got it yet

The delivery was perfect as always, packaging is bullet proof.

The set is definitely not for beginners, so you should have build some supercars less complex before that. Cada typical you will rotate the gear box more often then earth rotates in a year. This can be confusing.

In the end the set is very massive and the engines do have some problems to move it. It´s pretty fast for it´s weight but the battery will not last that long. So it´s more for a sprint race then long distance. But you can reach the box quite ok under a side panel to plugin the USB cable for charging.
