I'm only buying from nitrotek coz I can't find the product in China in in UK. Wot sort of a part company can't u fone? Crappy nitrotek. When I bought my cyclone I couldn't call them & find out any tracking information. If u want parts advice u gotta message, they normally return a message that annoys me. If u fone modelsport u could wait 15mins in a que, because they advise you like a friend even if there's no sale. Nitrotek won't do that. They make u wait up 48hr & incourage to buy only from them them
