Its not the size, its the technology... Its hard to fit good or high tech components inside a small rc car. For example, the 1973 mobile phone as big as a brick would be cheap today because it is easier to fit components in. However a new iphone or samsung or just any other brand would try hard to make phones slimmer, high quality, lightweight, and faster.So it would be more expensive considering the price of components (Sorry for writing an essay haha)
Had a terrible experience with that brand. Got one of the little blazers and with in 3 mins of run time a small weed got wrapped around the rear hub and broke the driveshaft.....took it to my local hobby shop to which I was informed they didn't carry parts and that he considered it "toy grade" ..... returned it bought a traxxas and now I have 4 traxxas trucks .... and 2 arrma. Spend a little more get a better product 🤷
