ive heard of the hammer head trick ive been trying to practice it in a spit16 ive been able to do it few times but its hard to get down i know its better for twin engines but does a bigger rudder help out more? idk it look like a good trick to learn and if you have any tips plz tell me
thanks 67COUGAR

A true hammerhead is an aerobatic, not an air combat maneuver. What you're looking for is the rudder reversal. There are a few reasons for the distinction. The aerobatic hammerhead is done pure vertical and at close to zero airspeed. Pure vertical may be, but isn't always, desired or required in ACM. Also, the slow speed does two things to you. First, it's harder to control and still be able to point your nose effectively until speed builds up on your way back down. Second, and maybe even more importantly, hanging up in the air at near zero airspeed in an air combat environment makes you an ideal target for another NME fighter in the area. You may as well have a neon sign on you that says "SHOOT ME". Another thing to consider is that AH aircraft don't do true aerobatic hammerheads very well but they all can easily do a rudder reversal.
While the rudder reversal can be stretched out to zero airspeed like a hammerhead if you need just a bit more altitude (and you're sure you aren't going to get picked), it's typically done at a higher airspeed while you still have good control. The key is to use yaw to rapidly turn the aircraft 180 degrees (a reversal) from a nose-high attitude and be able to kill the guy below you. As for tips remember a few things.
First, if you fly with Combat Trim on it will tend to add in more and more nose-up trim the slower you go. CT just works off a look-up table and sets trim according to speed, it doesn't care if you're going straight up or level, it'll give you the same trim and that'll make the airplane want to pitch over backward when you're going vertical so you need to either trim manually or hold forward stick to stop the nose at the desired angle.
Next, as you yaw the airplane with rudder, dihedral effect will want to roll the airplane into the yaw (left yaw = left roll). This can work out OK but if you really want a pure 180 then you'll need to use opposite aileron to stop the roll (left yaw = left roll = right stick to counter).
Last, the rudder reversal works best if you do it with the natural torque of the engine so for airplanes with props that rotate clockwise (most of AH's airplanes) you'll want to use left rudder. A few exceptions where right is better are those aircraft with counter-clockwise props like the Typhoon. Another exception are twins like the 38 with two counter-rotating props. The torque produced by the counter-rotating props cancel out so it'll go as easily to the right as to the left. If you want to do the reversal against torque, it's best to cut your power a bit to reduce the torque, especially when flying high-horsepower aircraft.
You last question is easy. Yes, theoretically, a larger rudder makes this easier to do but from a practical point of view all of AH's airplanes will do rudder reversals well.

Excellent writeup Mace.
These reversals are doable in almost all planes in the game but tricky to master. Most planes in AH I've found have a sweet spot in airspeed where with the right timing and combination of inputs you can pull off this reversal very quickly and surprise your enemy. The further you stray from this sweet spot the harder the manuver is to smoothly and quickly pull off, so experiment frequently and at varying airspeeds and with varying weight loads until you start yielding results you're happy with.

ok wow thanks really appreciate it<S> , mace id like to get your call sign in aceshigh so maybe you can show me how to actually do it but the reply really helps alot
thanks 67COUGAR

As usual Mace is spot on.
I would recommend rudder reversals only in tightly controlled circumstances. An example is a 1 v 1 duel in the DA or TA or an extremely isolated MA fight. Anytime you are nose high below minimum vertical maneuvering speed you are an easy target for an unseen attacker.
Perfect the technique in training because it will teach you to judge relative energy states with care but limit its use in any multi-threat environment as it will get you killed quite a lot.

I like doing them when I rope a con and want to blow his belly apart with a tater.

I enjoy using rudder reversals. I use it as needed and truly miss using them in the Old Pizza Map Canyons.

A true HH is very hard to do... If anyone can perform a true 1 please post it.. I posted a similar thread a couple years ago.. :salute

Its not perfect, but is this what you are talking about?

No this isn't hammerhead. Neat reversal though (wing over).

oh I was kinda going by this statement A true hammerhead is an aerobatic, not an air combat maneuver. What you're looking for is the rudder reversal.
I didn't get it to zero air speed nor was I perfectly vert.
Isn't a wing over when you have one of the wingtips stall out causing the plane to go upside down at the top; not just a reversal in the vert plane?

Would this be a hammerhead?

Nice wingover animation here

No.
You go straight up, until you reach 0 speed while still keeping nose up, kick in rudder, start sliding back and reverse 180 degrees (yaw only).

Bighorn that animation shows a rudder reversal. They call it a wing over but compare it to this USN video.

An aerobatic hammerhead doesn't include a tailslide. A hammerhead pivots around the yaw axis.

Note that the description is similar to the animation you linked, i.e. slow down enough then use rudder to rotate.

Its wingover, it's same as on that video (they double it up) and is also the same as on the page you referenced for hammerhead (scroll down to wingover)
Rudder reversal is what exactly?

Well, every reversal of the same type done in less than half the wingspan is called Hammerhead. Of you want absolutely no offset in reversal, you need to stop and tail slide for 'on the spot' reversal and rudder to work (need airflow over controls).
For offset larger than zero and less than 1/2 wingspan, you don't need to slow to zero, nor tail slide is required in that case (you got airflow over the rudder).

Rudder reversal is when you go up and use the rudder to yaw the nose around. Your animation link is a vertical climb with a rudder reversal, the wing over in the USN video is more of an arc, it starts with a climbing turn and you roll into and out of it. The wing over description in my aerobatics link also is a roll into a climbing turn and again gravity pulls the nose down not the rudder.

All depends how tight you want to have it. You can help the wing over with the rudder or not. There's no prescribed radius for wing over (as long as you stay in the box).
In fact, high yo yo isn't all that different either.
Anyway, for the purpose of game play, any kind of top reversal is fine if executed at the right time and done quickly enough to get a shot.
