Come on man, the Spark is almost as heavy as the avata and that´s the top speed of those FPV drones using racing props and high output battery. Close to 100 km/h is a huge speed for drones. With those, crap very thin floppy clip on propellers...
And one more, last thing: in able to speed up that fast, the drone has to be almost vertical. The drone just simply can´t do it, because after a certain agle, the drone shuts off.
This drone doesn´t fly this fast, because, the props are not...
I had this drone for years, flew it with dronemask a lot, it was hacked and everything, but never managed to fly faster, than 50. The 2nd thing, that those propellers are not designed for that speed. I use spec HQProps on my Avata2, full throttle...
I don´t know how is it possible. My spark had a top speed around 50 km/h. My only drone, that flies over 100km/h is the Avata2 in manual with 40 degree cam setting
