If you guys are so desperate
www.rc-car-online.de has MB, MT etc. in stock. They ship worldwide, speak english and their service are extremely good.
(funny that the MB costs 207$ LESS in europe compared to the US.
The CY engine is a chinese version of the Zenoah. CY is Cheng Yang - my brother has a CY in his MT, and it sounds, feels and performs just as good as the wellknown Zenoah which I have in my MB. So no problem there.
The exhaust are directed out the back on the "new" models - but its not a 05 design, because my 04 also had the exhaust pointed out the back. They keep improving the design, and the exhaust out the back is much better than down the side I would say - both because of the looks and because of the smoke, oil etc.
