hi all its been months since i bought this item thought i would give it a good run first .... well it sits in my rc18r with a 2cell 3000mah lipo and motor fan and i have not been able to fault it it is very quick ,smooth and with the program card they are heaps of different opptions for you to choose from ...slow to fast just depends on what u want .this is a very good set for the price considering the brushless set up i put in my rc18t cost $180.00 i will be definately buying another hobbywing for my next project
