This update adds the following... 1. Fixed a bug with the Cheyenne's load out screen which would prevent it from being removed causing it to overlay other helicopter loadout screens. 2. Fixed a few other errors being reported by the loadout screen for all helicopters. 3. Rebalanced the Cheyenne's engine power so that the MTOW is more realistic. As always, the MTOW is the maximum weight where the helicopter can hover outside of ground effect. 4. Added the AH-64D Cheyenne which is a modernised version. It loses the nose turret in favour of a Targeting Pod from the Viper as it was a perfect fit. It gains 2 extra hard points under the belly and a slightly improved engine. It can also carry a much wider array of weapons. The MTOW is slightly higher but it is still very easy to exceed. In these case's try a Short Rolling Take Off by setting PROP to 50% and then full collective! ːsteamhappyː 5. Tweaked the pusher prop so it will produce more power at low speeds allowing you to accelerate much faster shortening the transition time between hover and forward flight.
