ezrun 35a 13t combo v1.1
 

Just found the above in my wardrobe still new in box. I remember it costing about £70 but never got round to using it. Just wondering is there a lot of difference between this and the newer version v2.
Sticker on the box says EZRUN-25A-SL program card 13t-3500-300kv but the esc has 35A-sl V1.1 on it.
