I've made a quick tutorial for Topogun 3 since a lot of you had issues understanding the new tools and what's different from Topogun 2.
Buying topogun 2 now and then upgrading to Topogun 3 when the official release will come will be cheaper than buying 3 directly Also you get full access to Topogun 3 beta with the ability to save and export ;)
