My biggest pet peeve with helicopters is the required items to fly. I’m currently flying to Aconcagua and the needed items is so ridiculous that it take me a few hours to build them before I can send it flying. So far, i can only do 1-2 per day and i’m 34/50 toward 2nd star. Still remain the 3rd star, then Stanley and Mont Blanc. It’s also unrealistic to need so much items.
