Air Tabs Installed

The purpose of air tabs on an aircraft is to improve slow flight handling and reduce stall speed.
Their purpose on a metal box with attached a/c's, vents, antenna's etc seems ill defined at best. So far it looks like "lets stick 'em on & see what we get".
Without repeatable data based upon identical or nearly so configurations their value cannot be anything other than costly subjective hearsay.
YMMV
Good luck

In most part I agree, however isn't that the case with most scientific theories? impossible to get absolute proof, the Wright Bros. built a contraption based on it should/might (and a wind tunnel that every one on RV.net would laugh at if we tried to use it on our RV's) work with no proof it would work. It was accumulated failure and success (of themselves and others) that ultimately gave them the necessary knowledge to fly.

When do we ever get absolutes about most of lifes issue's such as,

when should I retire? should I retire in Detroit or Denver? should I invest in Apple or Blackberry? is it a good idea to marry that stripper? At times the best we do is throw educated guesses at some issues, the more accumulated knowledge we can amass (in this case a forum) the better of educated guess one can make.

Aerodynamic additions to our RV's are relatively low cost when one compares the cost of fuel over the RV's lifespan or the initial purchase price. I have under 100$ invested in my air deflector.
