Ez-runs are great
I have several that I race including the 9t combo and the 5.5t combo, they are fast and have not given me any faults in about 10 months of racing. everyone else I know that also has them have only good things to say about them.
£75 will get you a 5.5t motor , esc and program card. £58 will get you a 9t motor, esc and program card. its a no brainer.
