During my first assignment in the Air Force, I worked with a grizzled B-52 pilot who had been stationed at a SAC base in the upper midwest - somplace with lots of ranches and cattle.
While there, he and a friend owned an old Champ and one day came up with a great idea. They clamped welding rods on the lift struts, pointing forward, then got a bunch of cheap Estes rockets, slid 'em on the welding rods, and ran the launch wires into the cockpit. They then proceeded to make rocket attack runs on poor unsuspecting cows.
I think something like that would work well on your RV, CJ!
