Which is the better combo, in general? It seems, at times, that the XRS is starting to get more negative press in the speed and/or overall performance - plus hard to set up... On the other hand, what would a realistic top end be on the XRD/300 combo and what prop? I am still researching which one to buy (I currently have a XRS/250 Pro and will barley hit 80) in my research I have visited with Bullet and currently there is an approx. 9-10 month build period before delivery, lol, almost a year before I would get the new one... Plenty of time, I guess to sell my 2014.
