Hacker C50XL richard? thats the one! honest, how can you actually contimplate going YS when you can get a lecy setup for 300 quid more and never have to pay fuel. at 30 quid a gallon for good YS fuel youd use a gallon in 2 weeks, if not less......so, in 20 weeks, youll have paid the extra 300 off, then if you need to replace your lipos at 400 quid, youll pay that off pretty quick aswell, IC makes no sence any more to me......if i didnt already have the motor for my C50 id go leccy on that.......
