Milviz has released their expansion pack for their DHC-2 that they call “Spray N’ Play”. It consists of a STOL wing modification kit, straight floats and an agricultural-focused model with a completely functional crop duster.
It can be yours for only $14.99 USD over at the Milviz store but it requires the Milviz DHC-2 Beaver installed for it to work. That costs $39.99 USD. It supports both FSX with Acceleration pack or FSX Steam Edition as well as P3D V2 to 4 with the latest hotfixes installed.
This aircraft is “Award Winning Excellence,” as Milviz calls it: it comes with configurable fuselage styles, different propellers, and different visual and navigational options. It also includes in-depth systems modelling, custom start-up routine, WX Advantage weather radar, and more.
