The protos is wirth the money yo pay, it comes with an Axial .28 engine so it's not race legal, at least in Europe, but the average quality is really good for that price, I'll probably race the next truggy season with the Mantis.
I went with the Mantis Truggy from them and it is just unbelievable. Once the motor got broken in, I can't find a place big enough to unload all the power in.
The reviews I have read say good things about it, but the common supply for parts is a big concern.
