Over on their Facebook page, QualityWings Simulations has announced that they’ve pushed out a v1.5 update for their Ultimate 146 for FSX and Prepar3D v4.
This update comes in response to a string of bugs, issues and inaccuracies reported on the QualityWings Simulations forum by customers. Version 1.5 brings along crash to desktop fixes, improved aircraft behaviour to bring it closer to its real-world counterpart, an issue where gear and flaps would occasionally not retract and more which you can view in the complete changelog towards the end of this article.
Also, at the end of this article, you’ll find instructions for existing customers to update their product.
If you don’t already own the QualityWings Simulations Ultimate 146, you can grab a hold of it on Flight1.com for a price of $19.95 (Incl. VAT) for Prepar3D v4 or for FSX/SE also on Flight1.com for the same price.
