70cc twin V2
[H=1]Description of the maneuver[/H]
Can be performed with 360, 540, 720 degree spins inside of the "flip" which is composed of a flip and a roll. Pirouetting Flip Loops, Mobius, Piro-Flipping Figure 8's Vertically and Horizontally, Piro Tic-Toc are all variations of this maneuver
[H=2]Level of difficulty[/H]
Hard/Extreme. You should be comfortable with all orientations of the helicopter. While learning this maneuver you will get a sense of throttle management, control, and over-control. I recommend learning this maneuver as soon as possible.
[H=1]Performing the Maneuver[/H]
Start with half flips. Start learning a half flip by doing the elevator and rudder movements separately at first.
Start upright tail in.
Give a little positive pitch to keep the heli from falling
Push forward until the nose is pointing straight down.
Stop pushing forward then give left rudder until the tail is straight down.
Pull back on the stick to level out. You will be inverted with the tail facing you.
Stop there and regain control if you are a little off.
Keep doing this until you are comfortable. Gradually work the sticks in unison to smooth it out into a single roll/flip. Ultimately you want to start by pushing forward and giving left rudder at the same time. Then you should roll the cyclic stick clockwise until it gets to the 6 o'clock position. Timed right you will get a smooth roll and end with the heli inverted tail in.
Once tail in inverted you pull back on the stick and continue to give left rudder (same rudder all the time). You will roll the cyclic stick smoothly clockwise from the 6 o'clock position back to the 12 o'clock position. Again this should end up being a continuous smooth roll. You will end up where you started upright and tail in.
Practice each half slowly and eventually you can start to put them together to do a full half piro flip.
Full Piro Flips
You should be completely comfortable and dead on with half piros before considering upgrading to full piros. You should also be proficient in flips and rolls that end with the heli nose in inverted. I.E. practice nose in rolls and flips making sure you can stop halfway while still in control...
Start upright tail in again.
This time you will apply forward cyclic and left rudder again but you will need to give more left then with a half flip because you want a full piro rotation.
Stir the cyclic clockwise as before, but this time follow the tail completely around and stir in a complete circle. It's important to always stir with the speed of the tail. Watch the tail go around and move the stick around as it moves. It's a timing thing and the more you do it the sooner it will "click"
If timed right and all goes well you will end up inverted nose in.
Make sure to pause here and regain control before trying to flip back out.
When starting out just reset and start over at this point. Keep repeating this until you can get the heli to stop and correctly be at the inverted nose in position. Without being able to do this properly you will never get a clean piro flip.
The beauty here is you just do the exact same movements to get back to upright tail in again. Repeat this as many times as it takes to start to get this to look and feel right. This part was always easier for me because you end up upright again which was easier for me to regain full control of in case I'm a little off on the timing.
The important thing here is to stop at each half when you are learning. Do not try to do full flips when you are starting out. They will be very sloppy at best and you won't know why. Also doing one half at a time will make learning the timing of the stir with the tail much much easier. Work on each half slowly and don't start going again until you are back in control and the heli is centered and back in front of you if you drifted away. When you are ready you can start to link the two halfs together to become a seamless full flip.
As always if you are new to this stuff definitely only try this on a sim until you get a good idea of what you are doing. You are nearly guaranteed to crash doing this stuff.
[H=2]Steering[/H]
When steering the Piro Flip use positive or negative pitch to "pull" the helicopter in the direction you want it to go. (Represented in the video below).
[H=2]Exiting[/H]
When exiting, time the stop of the tail with the stop of the cyclic movements and exit in desired direction.
[H=1]Common mistakes[/H]
Mistakes:
1. To much collective
2. To much cyclic movement
3. Not taking your time
4. Trying this in real life without trying it on the simulator first
5. Breaking stuff
[H=1]Tips[/H]
1. ONLY use collective when the blades are level with the horizon, any other time the collective should be at 0 degrees.
2. Make slow large movements with the cyclic
3. Take your time through this maneuver
4. Don't get frustrated when you crash
5. Record yourself doing the maneuver and the inputs, then compare them to my video below.
6. TRY this on the simulator first!!!!
