Please refer to the map, the parking lot beside the 污水處理廠. We play on Sat. and when we have time. But not sure about this Sat. as there will be a Race this Sunday at TRC for 1/5 bikes.
They are both made by Nuova faor. The second one is the top of the line one. Hobby pro don't have it in stock (they only have the first one in stock) but you can ask the shop in KWS to order it for you. It will take around 1 month.
