First of all, I guess you're basing this on a no wind situation? And if you've always flown legally and maxed at 120 meters, how do you know that 200 meters might not be even better? I'd just like to know what you're using to make this judgment...imperical data or just a gut feeling.
Interesting statement,
Usually the higher the stronger the wind is.
What do you mean?
The connection/signal/gps is better?
Less interference?
It saves energy?
It goes faster?
Range on the spark is terrible with just little obstacles, houses and what not, but in large open space it manages ok, no way near the parrot bebop2 though. Remember this is phone only, no controller
