We are announcing our model of helicopter later today, also here is an update from one of our devs Destroyer121.
"…we are planning on working on the flight model, making it more heli-like. Once we feel comfortable with it, we will give it to the testers. It might take a few hours, a few days. We know that you all want a heli, and so do we! We also don’t want to rush anything, making it seem like an unfinished product, even for the beta testers"
