All I can say is that at least "some" companies when they release a product that "follows the lines" of another already proven design TRY to give it their own look and add their own twist and ideas to their creation. Sure the TRF201X is very much like a B4 at a glance, when you see it close, there are many subtle changes that make the Tamiya unique from the AE and vice versa, similiar with the RB5 and the Losi XXX, both similair but individual in their own way.
When it comes to the mid motor cars (X6, Cougar and CR2) they all "look" distinctly different to the eye IMHO...
THEN some companies come along and cannot be bothered to make things much different and just simply copy the mass of the car (geometry, appearance and layout) to the point that "some" parts even fit each other between the original and the copy.
It is obvious to see that the Team C car is "very much" like the X6 in every way visually, almost every part from the servo back looks "very" similiar in shape, design and appearance to an X6. However it is often said that copying is the best form of flattery and as Chazz has already added, if they are to copy then they will always be behind whilst new parts and ideas are being developed by the "creator" rather than the "immitator" and always behind in the availabilty etc
Add to this the fact that the materials used (as with many copies) will leave the car a little short in terms of quality and durabilty (IMHO) as is the case with many cars out there like this already....
It has been said elsewhere the customers have the choice now between the cost concious "copy" or the "real deal" with continuing development, ongoing R&D and support. Having spoken to many owners of the "other" copy cars that we have seen already in the last 18 months, many regretted their choice and got quickly fed up with poor back up, unreliability and poor quality and almost spent more on spares/replacements then they saved on the cheap kit in the first place.....
If it really was NOT a copy and people do not think it is or looks like one, then why has the thread been started in the "X-Factory" section?
