I ran across this video of a Savannah used in spraying applications. With a skinny pilot, you could have a useful load of about 35 gallons. I guess you could call it "spot spraying".

I could sure use that once in awhile. A deceased friend's old Sorensen belly tank and booms for a 180 Cessna are still out at the airport but wouldn't want to trash my airframe mounting it.

There was an article in the old Sport Pilot/Hot Kits & Homebuilts magazine years ago about a Rotax 582-powered agplane a guy designed & built for "personal" spraying called the Aeromaster. Carried 30 gallons dispensed via a "Spray Miser" rig. Looked pretty handy & affordable for a smalltime farmer, esp if you wanted to remove the spray rig & do some sport flying off-season. Danny Roche/AeroLites in Welsh LA was trying to market both the airplane & the spray equipment, don't know how that went for him though.

Danny was doing ok until Katrina. I heard the business did not recover. Most of his sales were going to Brazil where there were not as many regs on aerial applications. I have a Spray Miser ulv system that I bought for my 701 from Danny in 2002. It used a 12 volt pressure pump and each nozzle has an independently wind driven plastic prop to produce uniform droplet size. 25 gallon tank. Uses vegetable oils for carrier rather than water to improve coverage at low volumes. The Aerolite Aeromaster looked like a little ag plane. They were also starting to equip a twin engine ultralight out of florida for added flying safety.
Danny seemed like a good guy even when I needed service.

Correction to post.... I just found a 2010 contact for him, so let me give him a promo.
