FSX – Douglas D-558-2 Skyrocket Rocket Model v1.1. The rocket model D-558-2 Sky Rocket has been updated to V1.1. On my D-558-2, if the reality setting was hard, the battery died mid flight and all indicators were disabled. The voltage gradually decreased, and it was found that the cause was that the battery was not charged. I added a generator switch to the VC to control the generator. Along with that, some textures have been fixed. I was surprised that FSX was so real. This non-charging issue has also been fixed in D-558-2 Hyblid model v1.1, early model v1.
