Is there a mod to control usual helocopters like drones? Because if there is, this would make playing attack helicopter as gunner posible. Because when you fly NATO drone MQ-12 Falcon you can just go to reqired altitude turn on autohover, turn off autopilot, and switch to gunner. But when you play as gunner in choper, and you switch to manual control of helicopter, if there is the pilot he starts losing altitude right when you switch back, or if you fly without pilot even after turning autohover on, when you switch to gunner seat, helicopter starts falling. Maybe there is a trick to make pilot not doing anything, or when you are without pilot to stay hovering at same place, if there is please give me info. But otherwise it would be great to control helicopters as drones.
