I took notice to something recently and I thought I would get everyone to add what they know here. If it works I'll make it a sticky at the top so that everyone can find it.

There have been a rash of questions lately asking how to do this maneuver or that maneuver and I feel we need a single location to find all of these. I'd prefer to keep this related to 3D

So, tell us all how do a certain maneuver...or ask how to do one


THERE ARE NOW VIDEO CLIPS INCLUDED WITH ALL OF THE MANEUVER DESCRIPTIONS!!!

PLEASE GO BACK AND CHECK EM OUT!!!!!

Setup:
Slightly tailheavy ( the less elevator throw you have the more tail heavy you need to be.)
At least 45-70 degrees of elevator throw
High rate aileron
Max rudder deflection

How to:
1.Get the airplane up high maybe 300' to start
2. Chop the throttle and dive the aiplane vertcially, straight down.
3. Immediately give full left aileron input and get several rotations until the plane is rolling fast.
Simultaneously (but ever so slightly lead with full down elevator) feed in full down elevator, full right rudder and half to full throttle. The plane will violently wrap into an inverted flat spin.
4. As it settles into the inverted flat spin, continue to hold full down and full rudder and bring the ailerons back to center. This should level out the flat spin.
5. Adjust the throttle and ailerons to flatten out the spins and slow the descent.

If you get it right the plane will descend vertically flat on its back wrapping tightly around its cg axis.

Status: offline 		Waterfall
Setup: Same as the Blender
Maximum down elevator deflection (As much as you can possibly get)

How to:
1. Level the wings or climb vertically until the plane comes to a stop in a hover stance.
2. Full down elevator, hold and apply full throttle.
3. The plane should flip inverted in a pivot right around the wingtube ( For me, the radius of the pivot is the same as the distance from the tip of the tail to the wingtube)
4. As the plane wraps to inverted chop the throttle and then back to full throttle as the plane comes back up. Hammer the throttle to punch it completely over the top and get right back out at it flops over. Sometimes you can leave the throttle in if it falls just right.
a. You have to rudder correct quite a bit in this maneuver to keep it straight. I personally watch the tail of the plane and push it where I want when the plane is pointing vertically nose up or nose down.

How do you know you have it right?
The plane will totally lose lift and start to fall rapidly as it waterfalls over and over. Sometimes if you hit it just right the plane will accelerate into an extremly fast waterfall rapidly spinning right over the wingtube axis.

To recover, simply get off of the trottle and elevator and fly out.

The trick is to enter and exit manuevers in a fluid manner constantly transitioning from one thing to the next, or at least have a good setup transition to get you to the next maneuver.

Status: offline 		Knife Edge Spin

Setup same as waterfall

How to:
1. From a knife edge or vertical stance really high up, apply full down elevator, and then in the same direction full rudder and full aileron. Basically just pin the elevator/aileron stick all the way over.
2. Adjust the throttle and aileron to keep it in a knife edge position. I normally can hold it there just keeping everything at full deflection and adjsuting the throttle.

The entry is the key, if you dont get it just right you wil end up in an inverted flat spin. The trick for me is dont mess around. SHove the sticks to full deflection and go straight to around 1/2 throttle. It will immediately fall right in.

This is another manuever that eats altitude in a hurry. Be sure to be plenty high and give yourself time to recover.

Same setup as above

1. Slow the plane to just slightly above stall speed. Point the nose down and then sharply feed in full up elevaotr and keep it there, do not let back out, hold full deflection. Start out high until you get the feel for it.
2. As the airplane stands up chop the throttle so that it does not stand up vertically or flip over. It will start to sink fast, wings level and slightly nose high.
3. Immediately begin to ease in the throttle until it stops sinking and then control forward motion and altitude with throttle ONLY. You wil probably be pulsing the throttle a bit to hold it in the high alpha attitude.
4. Use the ailerons only to keep the wings level
5. Steer the airplane with the rudder only. No ailerons to steer.

The key issue is going to be managing wingrock. The wings are going to stall alaternately and rock back and forth a little. Best thing you can do is use the ailerons to minimize.
That and/or,
a. lighten the airplane
b. check lateral balance
c. Add a spoileron mix to lift your ailerons either to a set deflection on a switch, or to work in conjunction with the elevators.
You should not NEED the mix. If the plane is light and if you set it up right, wingrock will not e an issue and in time you will manage it with aileron control

Last thing.
As you turn the airplane be super careful until you get accustomed to how the plane handles, typically the plane is gong to want to drop a wing a little ( You are giving the textbook inputs for a snap roll) Just be thinking ahead and adjust the ailerons ahead of time to keep the wings level as you steer. This will be especially apparent on a downwind turn where you are turning the nose out of the wind and putting your tail to the wind. This is the riskiest time and when the plane is really going to want to lose altitude and tipstall. You have to be " on" and ahead with the ailerons and throttle.

Status: offline 		Rolling Harrier:

If you understand the 4 point roll, then you will understand the stick movements in the rolling harrier.
Entering the rolling harrier is really easy but the ability to fly it depends on your plane setup and the plane itself.

Lets start out with one direction first. Remember you will need full 3D rates for this:

1. Begin with holding right aileron.

2. As your plane begins its roll to the right feed in left rudder and about the same time down elevator (this will bring you through the knife edge / inverted portion)

3. 4. as your plane begins to the other side feed in right rudder and about the same time up elevator (this will bring you through the other knife edge / up right portion)

4. Depending on where you want to direct your plane you will need to goose the throttle about every 1/4 turn of the move.

Every plane has a slightly different feel in this move. It will take a lot of sim time and a lot of practice.

Start out with rolling circles first and then move into this when you get the feel. Giving more or less rudder or elevator will also help you steer the plane around. I find that if I feed in throttle inverted or upright during the rolling harrier it keeps the plane going straight.

Feed in too much throttle and your plane will pull out. Too much rudder and or elevator and your plane will also clim / pull out. You might also try letting up on the aileron input to slow things down if your plane gets moving. You have to keep up with the rudder and getting the stick movements is the key to doing this IMHO. Once you think you got it down, try it in the other direction.

Status: offline 		Comment regarding the Rolling Harrier

The descprition above is good I just want to qualify one thing. Adding the control inputs early
quote:

(feed in left rudder and about the same time down elevator )
works, actually the next input is more early than at about the same time, to do a rolling harrier circle. Effectively what is happening is the rudder and elevator are alternating duties. 1/2 of the time the elevator is acting as the rudder and vice versa.

Too Add.

Straight Line Rolling Hariers are similar but the control inputs have to be timed better so that you DO NOT input early or late. You have to hit the rudder/elevator inputs spot on to keep the airplaen going in a straight line. For me straight line rolling harriers were the most difficult of all to learn.

Wall

Fly forward wings level at about 1/2 throttle. Simultanously chop the throttle and pull full up 3D rate elevator. The airplane should stand up sharply on its tail, without gaining any altitude. When it stands up re apply the throttle to keep it in a vertical position to transition into a hover or whatever your next maneuver will be.

You can also use a similar version to popup into a hover from a lower speed. Its not as violent but it gets you into the right attitude to harrier, or pull on up into a hover.

Be sure to watch both videos..

Requires 45-70 degrees of elevator throw and an aft CG.

1. From an elevated position, push full down elevator and dive the airplane vertically, straight down.
2. Once the plane has accelerated and has some momentum, pull full up elevator sharply and hold.
2a. If the plane does n t pop into a harrier stance but descends nose slightly down
1. Move the CG back or increase elevator throw.
2. As you pull full up, pulse the throttle pretty hard to help pop the nose up. Then immediately adjust the throttle to maintain the harrier attitude, or transition into the next maneuver.

Status: offline 		Inverted Flat Spin

Requires High rate rudder and elevator and aft CG.

1. From any attitude, push full down elevator, full right rudder and full left aileron.
2. As the plane starts to flatten out continue to hold full down and full right rudder, ease the ailerons back to center.
3. Adjust ailerons as needed to level the wings. Adjust the throttle to keep the nose level.

Variations
To make a nice transition, slowly ease off of the rudder and let it come back to center a little at a time, adjusting throttle and ailerons to control attitude and wings level. The spin will start to open up into a flat circle and the diameter will increase as you let off the rudder. The the spin rate should decrease to a slow lazy flat inverted turn and look like a lazt falling leaf. From here you can transition into an inverted harrier, rolling harrier etc...

Status: offline 		Upright Flat Spin

Same setup as above.

1. Chop the throttle and ease in high rate elevator until the plane stalls.
2, Input full up elevator, full left aileron and full left rudder and the plane will start to spin.
3. As the plane starts to spins hold full elevator and rudder and let the ailerons come back to neutral.
4. Adjust the throttle to keep the nose level. You may have to adjust the elevator a little, but if you play the throttle right and dont add too much, you should be able to hold full up.


The plane will spin either but to the left it works better because you are working with instead of against other forces.

Variation

Let out of the rudder slowly to decrease the rate of spin. The spin will slow and eventually open up into a flat spin/turn.

To transition from upright spin to inverted spin simply move the sticks from one spin to the other, Just make sure that you input to keep the rotation of the spin the same. IE if you are spinning inverted clockwise make sure that you move into an upright spin that will continue clockwise. This normally means siomply crossing over with the ailerons and applying full up elevator, or vice versa depending on what you are doing.

Im am including a second video of what the transitions look like.
