You get wha you paid for.
Having owned losi and Kyosho I will say Kyosho has the best quality and parts.
With Kyosho you can feel every thread biting into the carbon composite parts and they do not back out unlike other brands.
Losi metals are made out of noodles IMO. Like all my 2wd Kyosho cars a lot that I'm gonna sell all my losi cars.
Btw what car are you looking at?
