HA- 6M hover

I want to know how come the HA-M6 can only hover 50 to 75 feet above the ground and sometimes I can’t increase my hover to look over the trees and when this helicopter should be able to hover from it’s Turbine-engine helicopters can reach around 25,000 feet. But the maximum height at which a helicopter can hover is much lower - a high-performance helicopter can hover at 10,400 feet*. However, if the helicopter is hovering close to high ground - its maximum hover altitude will be higher. So on that note can’t you guys get anything right I mean I’ve had this problem with other helicopters in this game and it’s! Not right you should be able to hover at 10,000 feet above the ground if it’s a turbine engine helicopter
