(Tail Arm ÷ main wing MAC) X (Tail surface area ÷ wing area) = .55 or greater Tail Arm is the distance from the C of G to the 30% chord point of the horizontal tail. .55 minimum is for a symmetrical … airfoil section tail typical of light planes like Cessna 150s. …

The stab angle influences the pitch attitude in cruise, allowing the body of the machine to be flatter (more nose up) than it would be without it, by pushing down on the tail with speed. …

No. Rudder authority on these airplanes is a function of yaw power requirements in the worst case asymmetric thrust condition and fin size is related to that and also related to the natural yaw dampi …

How much and where you add that weight doesn't matter as long as you move the C of G forward into the allowable range, and you don't exceed the maximum all up weight. 1000 lbs added to the tail 50 ft … The forward limit is a function of the ability of the tail to generate trimming downforce in the most extreme-demand case, which is usually raising the nose for takeoff and landing around the fulcrum of …

The fixed tail surfaces are to provide a passive weathervaning effect for stability. … And airplane like the Cardinal or Cherokee, with a manually operated stabilator tail, would be pretty difficult to control without the anti-servo tab. …

The horizontal tail is quite different. … The result is torsional overloads of the horizontal tail will tend to brake apart the structure inside the tail cone itself rather than the horizontal stabilizer box or its hinge lugs, whereas the fin …

A flat piece of wood with rounded edges will work fine. The tail's job of producing downforce doesn't require the lift coefficients or angle of attack range required of the main wing, so the actual …

stabilons are fixed surfaces that add effective stabilizer area to improve the center of gravity range, and also, by their location, add that additional surface area in a low location that mitigates the tail … So they would have just increased the area of the existing stabilizer, but that didn't fix the stall issues which are inherent to the T tail. …

The beauty of the pure delta configuration was you could get a reasonably low supersonic drag configuration in a planform with a lot of wing area, essential for really high altitude cruise and for rea …

Yes it can be fixed by replacing the stabilizers and wings which just bolt on. Replacements are readily available in the used parts market for 152s. Generally with metal that's been subject to a sing …

It's done to get a little more lift coefficient, and hence more tail downforce power, at low speeds and there is a drag penalty to take depending on how much camber. … The Zenith STOL family are the extreme example, and being draggy flying lunchboxes anyway, the penalty is minor in relation to the benefit and allows a smaller, lighter tail unit than would be needed otherwise …
