Yep, even in the country of origin. The factory is 20 miles from my home, that's why I drive a Yokomo. Besides that Serpent is brand for gas racers, let them stick to them. I have seen so man project going by this factory during the more than 25 yrs of racing. This car will be off the market within 2 years just like the offroad buggy about 20 year ago they tried to market. It was gone within a couple of months because they wanted to concentrate on the onroad gassers.
Go for a chassis which has a good support for sparepart whether it is in a onlineshop or your LHS
