I do not understand.. Yo say 1.5 meter High to achieve 4 meter wide, however the results show that 1.5m high provides a 3,6 meter wide..

According to the MG-1S manual, the relation between altitude and spray width is: @1.5 mt.= 4.00 mt. / @3 mt.= 6.00 mt. The field test shows that for 1.5 mt., the spray width is 3.6 mt. , not much of a difference with the 4.00 mt. stated in the manual. Once you start flying higher, the spray is affected by wind, temperature and rotors turbulence, so expect getting a lot less performance in spray width as you increase your operation altitude.

Confirmed, I can tell the difference when I fly above 2 m high.
I am flying at 2 m high with 4 m wide, but it is taking longer..

Great information. Can you please confirm which nozzles you were using for this test, you show that you are using xr11001 (110deg) to the side of you illustration,  but your nozzle angle is drawn at 80deg?
This may explain some difference from the manual perhaps?

Hi Vaughan, the test was performed with four Teejet XR11001-VF nozzles, these are standard MG-1S´s.
The Agras manual did not specify if these nozzles have an 80 or 110 degrees opening, but I made some measurements and seems to me they are 80 degrees.

For sure if you fly at the same altitude with the 110 nozzles, you will get wider lines and smaller droplets. Maybe the manual is working with a 110, not an 80 degree.

Thanks for the comment, I will check and let you know.

Yes, you are right about the illustration, the opening is 110 degrees, not 80.

Thanks for the observation.
