Their previous project for FSX is listed for $39.95, so that's a pretty good deal for upgrading to P3D with all the other giveaways this season. BTW, does P3D ever go on sale?
EDIT: looking further back into the posts, this may be the new project that was revealed only a few days ago :https://digitalflightwire.com/flight-replicas-announces-piper-super-cub-project/ so, not exactly a update of the previous package.
