I was tempted to buy the wizard X220 from Grayson hobbies, but keep the setup they do to it before they ship it out. I was a bit worried about not having any hands on help with Betaflight, but I just found a local group of people that are flying race drones, this evening so I might end up going with the Diatone Tyrant S and use the Turnigy Evolution. Just have to decide if I want to wait until September to get one (they are backordered)
