Looking good man, hows the new HB tires grip?

 

[dezman]

cheers the tires have loads of grip on grass and dirt and its not bad on road aswell its got loads of torqe and just screams till its flat out the 990 carb made a huge difference


the exaust is off a fg marder its got a much bigger outlet then the stock dunerunners it gives loads of bottom end pull and sounds waspy i'm thinkin about a baja ss pipe

chevy it probably wont make any difference its basicly a wt-813 improved for rc use it does make the car fly tho

This is the BRAND NEW coverted 990 CARB now fitted to all


Zenoah G270 and G290 4 Bolt V2. engines.


This already de chocked carb from the factory offers a HUGE upgrade against the stock 603, the upgraded 668 and the 813.


With out having the accelerator pump in this carb is MUCH easier to tune and performs just as well.


heres some more info i found

Very cool, I like the dunerunner more every time I see it, I don't think you can go wrong with any of the gas Rampage's.
