Well i had 2 now i only got 1. there a bit pricy but there fast and handle like a 1/10 scale car. the 3rd party suport for it is allmost bigger than the hpi suport. it has adj. wheelbase width ect. you need to get a chassy made for the big block if you use 1 becoue it has binding in the motor pod. i use a ratzas pro pan chassy http://www.ratzas.net and soft ratzas hole’s there tires.
this are the upgrades you need if you plan on useing a big block.
new chassy dont really need it but its nice ta have 1
steel or alu. front unaversals the plastic stock’s get blowen out
stock it will do about 18 mph mine is doing close to 54.6 mph but theres not a stock part on my car.
also you might wanna do what i did and buld your own insted of buying a kit if you wanna do that i can get you a part list of all the stock parts and then if you want you can change them to alu. or what not.
