some of the more advanced units are fully automatic to match flow rate with speed after they're calibrated. I obviously have no capacity to do that with my setup. I'm still working on finishing touches to my spray bar to get the distance out of the wings, it didn't spray as far as I anticipated from 15", I have plenty of material flow, but not the distance I was expecting.
Maybe we can grab lunch someday, I'm taking a Pesticide course up in West Hartford on Thursdays for the next two months. I come right down 84 on the way back. I can toss the spray unit in one time and let you look it over, we could run some water too if you'd like.
The next unit I make will be more simple, larger and faster.
350gallon unit, 120+GPM pump on a Honda engine, rotating nozzle bodys (plugs to turn them off, fan sprays for anti-icing, and jet-streams for de-icing). I can afford a little more waste when I have a 350gallon tank versus squeezing every ounce out of a 60Gallon tank.
