There's a lot of interesting comments here.
Here's my take on it...
If Team C is a China manufacturer, then copyright laws are non-existence. Team China?
Whether or not they are a direct copy is open to debate. What we have to remember is that most shells produced are scaled to 257mm wheelbase and 190mm width. Also there is only one shape of an M3 otherwise it would not be an M3. Hope that makes sense.
If they are knock offs, I would like to know of who, as I have not come across another manufacturer selling the McLaren P1. Maybe I have not looked hard enough.
L&L Models are selling Team C products. This is evident by the TC part number.
I don't believe L&L Models are trying to pass them off as their products. They are just a vendor selling a product line.
I don't think L&L Models have Frewer moulds, just acquired old stock. I make this comment because they only have a couple of styles. I could be wrong here.
If I see a product that suites my requirements and is of a good price, in the realms of RC cars, then I will buy it - irrespective of who made it and/or whether it is a copy/counterfeit.
In conclusion, I am very happy with my 2 McLaren P1 purchases.
