 We just had our last tail of aircraft 548 roll out of Kiln, Mississippi with the new NP-2000 propeller mod. That's where they removed the old 54H-64 bladed props, swap them out with the NP-2000 eight bladed props and increased performance and flying capabilities of these aircraft. These are our brand new NP-2000 propellers that we just got back from modification earlier last year. It's a hundred percent modular system and we're able to change the blades independently right here on the aircraft. Every piece of this can be changed without having to remove the motor or the propeller. We are the first unit in the international guard to get all eight of our tails modified with these NP-2000 props. These new propellers add a lot of new life to the aircraft. Floraudal responsiveness, reliability, and they do such a great job for us. We can't go wrong here.
