Funnels and Hurricanes
I spent some time searching for the name of a move to make sure it was the correct name: tic toc funnels. I decided to start writing some tips for this move, but then realized I have not explained how to perform funnels so I will do that now. I did not bring my laptop charger today so I won't be able to refer to the sim like I usually do so, if need be, I will edit this tonight after the gig.
Hurricanes
Make sure you are very comfortable with circles/circuits in all directions and orientations. Once you can do a circuit, try to perform this at a decent speed depending on your comfort level. After picking up some speed, put more of a bank into the circuit. Now you are doing hurricanes. Even though some may not consider an upright, nose first hurricane a true hurricane, it still is. But most of the popular versions are inverted forwards, inverted backwards, or upright backwards. The best way to get comfortable with doing a hurricane is to practice circles and figure eights. Then as you gain more confidence and build up speed, you will start banking the helicopter more. Try your best to make the circle even, as in try to keep the edge of the circle at the same distance from center line on both sides. To picture this, look up Inscribed Angle so you can see where the points lie in the circle. If you think of yourself as point B, the best viewing angles will be point A and C because you will see the rotor disc a little clearer in judging the distance. For some this may not work but it is something I think about.
Now, try doing a backwards circuit and as you gain speed, think about your rudder adjustments so the tail does not dip or raise which would produce an uneven circle. The next step would be to work on forwards and backwards inverted. If you decide to try this on the real heli first, make sure you have plenty of altitude in case you make a mistake. But it is best to perfect these on the sim first.
Funnels
Once you can do a hurricane you should be able to perform funnels. A funnel is like doing a circuit, but sideways. For car people, think of a drift competition. For an example, I will describe an upright tail in funnel. For your first attempts, begin in backwards flight, as if you are going to do a backwards hurricane. Use a slight rudder input to bring the tail into the center of the circle. For instance, if you are performing a clockwise funnel, the right side (passenger side) of the helicopter is leading the helicopter around the circle. The tail is constantly pointing towards the center of the circle. So you should give a right aileron input to get the helicopter to move to the right, but add some rudder input to keep the tail into the center of the circle. Pull back on the elevator stick to adjust the angle and add more positive pitch to keep the helicopter from descending.
Practice this without any sort of angle initially. Once this becomes easy, gradually increase the angle's degree. Depending on how steep the angle is and the speed you are travelling a large funnel or small funnel will be the result. This maneuver takes some time to get very smooth and even. Practice with more altitude then you might think you need. I noticed today that to keep the heli in a good line, I kept giving very very small positive and negative inputs. If I saw the helicopter lose altitude, I would add more positive pitch, but then go back to zero so the heli did not rise out of the circle's "line", and this continued during the funnel until it felt like I wasn't giving any inputs, but still probably moving maybe 1/2 a mm.
Next, try them inverted, as well as nose-in and nose-in inverted. If you can picture yourself moving the helicopter in a circle, only sideways, funnels will eventually be easy. There are lots of videos online if you need to see what a funnel looks like.
Make sure you have fun with this, otherwise its not right!
