max diameter 0.75 inch (19 mm) min 0.5 inch (13.5 mm); distance between these points 0.25 inch
If you remember the photo I sent you I´m using an air intake trumpet about 0.9 inch long with the big diameter of 0.8 inch and the little one about 0.6 inch. May be there is the problem. now I can see there is no difference between using the trumpet or not as the diameter differences are equal (0.25-0.30 inch)
I will remove the trumpet for todays flight.
