250 a battery and you need 6 to take off! I’m taking 36 so with hot charging we shouldn’t have much downtime. It’s not about speed but the images, 48MP needs a big heavy camera but only this size will show those minuscule cracks were looking forHappy days. We used a company called cyberhawk. Good blokes (and a lady). I took a team up to trial flying one on the inside of a blade both in the bunny ears and down the vertical. The lead pilot asked if I wanted to have a go but I made my excuses and declined. Bit too expensive if I messed it up! If I remember correctly your batteries are wildly expensive too so best of luck with it. Hope you get good weather.
