Some good advice above regarding chargers and using a simulator. The only problems I’ve had with the wizards that I have were forever burning out esc’s and motors, mostly through my own stupidity. I have since upgraded the esc’s to 30A and invested in a set of quality motors. Haven’t had an issue since, also upgraded the camera on one of them to a RunCam split, upgraded the vtx to a better eachine unit and it’s certainly a better quad for it. The wizards are a good learning quad when set up correctly in betaflight although I quickly realised that my money was better spent on quality goggles, spare parts and ultimately a better quad. Thou shalt have a lot of fun in this hobby!
