there are people who use them on the Facebook page "the spark side" its mod group you can join. That is where i first heard about it. The owner of UAV mods had commented on someones post. That is how i found out about it. And when they were in stock he emailed me and I ordered one. Just did not have time to get the
battery and changer to start using it.
I do agree you can get 10k ft and back for a total of 20k ft on the stock battery9i think that would be the max i would push it on the stock
battery). There are a few things i think that will get you there or further faster.
-sport mode(or sport mode ++ if you use super patcher)
-sats in place asap as not to waste
battery (this is very fast and the count goes up to 20-30 if you use super patcher 2.0 because you also get Galileo sats . In my areas i would get between 10-12 now i get 20-28 and in an open area i now get 30 max.)
That update is worth it just for that alone that is to me the best thing about it.
