Hi Rc Zombies, how are you finding the Hara Edition Pro 4 ? I have only just run my pro 4 for 2 x race meets now on carpet indoors.It is only the original kit, not even the v 1.1, but i was surprised how competitive it was. I hear the newer kits have a different setup to my original kit. What is your take on this ? I am looking at purchasing the Hara kit to run outdoors on bitumen tracks only, & keep the " old girl " for carpet
