Or going darkside, tracking riders on the TdF/Vuelta etc? Rather than getting camera footage from a helicopter positioned a few hundred metres away, just have drones picking up the footage close to the action. Would also mean motorbikes don’t have to tail a rider doing 60mph down an alpine descent. Being able to flick between drones could make footage of racing really intensive.
Almost impossible in road racing. That MTB shot is relatively easy since it’s one rider and can probably be staggered, staged, re-run etc. Also it’ll be on a fairly small overall area to maintain FPV flying and transmission range.
Trying that in a road race on a much longer range at much higher speeds in a pack is going to be insanely difficult. There’s the risk of crashing them into spectators or riders too which is considerably reduced when it’s one rider on a DH course.
Battery life is going to be 20 minutes max at those sort of speeds and manouevres as well.
