I took Air 2 (more combo), and not mini 2 and not Air 2s - because: the mini does not like strong winds and the maximum height is 4000m - it is already difficult to fly on Elbrus (altitude 3847 on the upper observation deck near the cable car, but it can no longer be higher + byvakt strong wind). I did not take Air 2s because of the price - it still bites, and you can ask for a discount on Air 2. After Air 2 I wanted FPV.
