How to Win  

 

Model Helicopter World, leading Worldwide Helicopter Magazine, has carried a series of articles on how to win the World's premier 3D event. Written by Russ Deakin, regular columnist with Model Helicopter World and Judge for 3D Masters 2001, 2002, 2003, 2004 and 2005, the articles describe each of the 30 Set Manoeuvres in detail, and how they should be flown.

Set Manoeuvre 1 k=1 This manoeuvre is entered from backward flight, ideally into wind and as the model is level with the judges, introduce positive collective pitch, with a moderate amount of forward cyclic to initiate the first quarter of the loop. From here, the collective pitch is reduced to around zero degrees and with the help of momentum and the sustained forward cyclic input, the model continues over towards the inverted section. Here, a smooth change to a negative collective pitch requirement of around minus 3-5° should have been completed to halt any loss in altitude and retain motion. From here, the model heads towards the three-quarter marker, where the collective pitch requirement is to be changed through zero degrees and is well on its way back to a positive value as the model nears the exit point. Backwards Loop
Set Manoeuvre 2 k=1 The two backward rolls should be entered from medium speed backward flight. As the model rolls over to the first 90° knife edge position, collective pitch should have been reduced to a zero value. Then, as the model continues towards the inverted section, pitch is changed to a negative value of around minus 3-5°, with a small temporary shove of well timed forward cyclic being used to push the tail down and keep the momentum. From here, collective pitch is once again reduced to zero degrees as the model enters the next knife-edge position and back to positive as upright flight is returned to completing the first roll. At this point, you will probably need to instigate a small temporary shove of back cyclic to keep the model moving and as you progress on to the second roll, control requirements are a simple repeat of the above. Backward Rolls (2)
Set Manoeuvre 3 k=1 The general idea here is to settle the model helicopter into a stable inverted hover at a height that you feel comfortable with and in a good position for the judges. Then two slow to medium speed pirouettes are performed, with cyclic control being used throughout to hold the model truly stationary, whilst collective is adjusted to retain a constant altitude. Inverted Pirouettes (2)
Set Manoeuvre 4 k=1 To perform an outside loop, the model should be positioned at a safe height and the manoeuvre is entered at medium speed and hopefully, downwind. Then as the model comes in line with the pilot/judges, forward cyclic is used to push the nose of the model down into the manoeuvre. From here, pitch is reduced to zero as the model nears the first quarter and as the model continues on towards the inverted section, collective pitch should have been changed to a negative setting of around minus 3-5°. Now allow the  model to carry on towards the three-quarter point, where pitch will be reduced to around zero degrees with a final transition back towards positive pitch as the model exits the manoeuvre. Outside Loop
Set Manoeuvre 5 k=1 This visually dramatic manoeuvre is best described a s amedium-high speed sideways flight remote circuit. The speed and aggression of the manoeuvre dictates that the tailboom will be near vertical while the model is travelling in a sideways motion. We require 4 complete remote circles to be performed in flowing succession. Pie Dish
Set Manoeuvre 6 k=1 To perform the two stationary forward/backward flips, the pilot should position the model so that it is line with the judges and at a height they feel comfortable with. Then either fore or aft cyclic is used in conjunction with a small amount of additional positive pitch to send the model towards the first quarter of the flip. Here, collective pitch will have been changed to that of zero degrees and as the model enters the inverted section negative pitch is used to retain altitude. Then as the model continues to rotate towards the next vertical, pitch should have been smoothly change to zero and back to a positive value as the model becomes upright again. Then the process is simply repeated to enable the second and final flip to take place Flips
Set Manoeuvre 7 k=1 The contestant must perform one inverted figure eight in the forward flight direction. For maximum points, the manoeuvre must be flown at a constant altitude and speed with the crossover point directly in front of the judges. The left and right hand sections of the manoeuvre should be symmetrical and the judges are expecting this manoeuvre to be flown at slow to medium speed so that the pilot can display full control over the model in all orientations. Figure 8 Inverted Circuit
Set Manoeuvre 8 k=1.5 The contestant must perform one loop while constantly tumbling in the forward or backward direction of fore/aft cyclic. Maximum points will be awarded for a constant rate of tumbling and overall motion of the helicopter throughout the manoeuvre. In addition to this, the manoeuvre should be symmetrical in shape with the start and finish points directly in line with the judges Tumbling Loop
Set Manoeuvre 9 k=1.5 The contestant must perform a sideways loop while continuously rolling on roll cyclic. Maximum points will be awarded for a constant rate of roll and overall motion of the helicopter throughout the manoeuvre. In addition to this, the manoeuvre should be symmetrical in shape with the start and finish points directly in line with the judges. Sideways Aileron Rolling Loop
Set Manoeuvre 10 k=1.5 The contestant must perform one inverted circuit whilst the nose of the model continuously points to the centre of the circuit. Maximum points will be awarded for a slow, flat, symmetrical, constant altitude example that is centred on the judges and allows them to ascertain the pilot has full control over the model Inverted nose-in circuit
Set Manoeuvre 11 k=1.5 This manoeuvre should be entered from level inverted backward flight into any wind present, whilst being at medium speed and altitude. Then as the model comes in line with the judges, the forward cyclic used to build motion is changed to a back cyclic command and some additional negative pitch is added. This sends the model up into the loop and as the first quarter approaches, collective pitch should have been changed to around zero degrees. As the model continues over to the upright upper section, positive pitch is used to retain altitude and motion. From here, the model is allowed to fall backwards to the three-quarter position, where pitch has been progressively changed to around zero degrees. Then, as the model attitude returns to inverted backward flight, negative pitch is used to halt the descent and exit the manoeuvre. Inverted Backwards Loop
Set Manoeuvre 12 k=1.5 A knife edge pirouette should be entered from medium forward speed and altitude, with the manoeuvre being executed in line with the judges. Whilst several combinations are possible, the most common is to enter the manoeuvre from upright level flight and use a slight kick on back cyclic to gain some extra altitude. Then a one-quarter roll to the right is used to swiftly send the model over to knife-edge and full right tail rotor is applied so that a sprightly 360° pirouette is released. Once complete, a one-quarter roll to the left followed by a touch of forward cyclic is used to return the model helicopter to its previous upright forward flight path. Knife-edge Pirouette
Set Manoeuvre 13 k=1.5 This manoeuvre is performed while the model is travelling forward at low to medium speed (pirouetting rolls). The idea is to continuously perform two pirouetting rolls/flips with no hesitations throughout. The model should enter the manoeuvre level with the judges and exit the manoeuvre with the tail/direction of travel being identical to the start position Pirouetteing Roll/Flip (2)
Set Manoeuvre 14 k=1.5 This innovative manoeuvre consists of a minimum of 4 opposing near-knife-edge crescents joined in a flowing snake-like motion. The manoeuvre must be perfomed along the flightline with a horizontal tailboom and with alternating forward/backward cyclic as the opposing crescents are performed. Snake
Set Manoeuvre 15 k=2 The backward rolling circle should be performed at medium height and speed with the remote circle being performed directly in line with the judges. The general idea is to continuously backward roll your model helicopter at your preferred rate of roll rotation and whilst the model is rolling at a consistent rate, steer the model around a remote circle in either a left or right hand direction Backward Rolling Circle
Set Manoeuvre 16 k=2 The inverted pirouetting figure eight should be performed in front of the judges in a remote figure eight. The manoeuvre is best performed at low to medium speed, whilst the tail rotor is continuously rotating at a consistent rate Inverted Pirouetting Figure 8
Set Manoeuvre 17 k=2 This rather technical manoeuvre is best performed at medium speed and altitude and in line with the judges. The general idea is to fly into the manoeuvre at speed and just prior to the start position, set a consistent rate of rotation on the tail. The actual rate of rotation can range from very slow to quite fast and it really is down to the pilot which rate suits them best. Then by using both pitch and cyclic control, the model is steered around a loop while the tail is constantly rotating, until the model exits the manoeuvre Pirouetting Loop
Set Manoeuvre 18 k=2 The pirouetting outside loop is practically identical to its slightly more conventional counterpart, but further complication is added by its inverted requirement. So instead of starting the manoeuvre in an upright position at the bottom of the loop, the model enters this variety from upright flight from the top of the loop. Then collective pitch inputs are well backed off as the model drops down into the manoeuvre, with plenty of collective being used to haul the model back up to the exit position Pirouetting Outside Loop
Set Manoeuvre 19 k=2 The Chaos manoeuvre should be performed in clear vision of the judges at around medium altitude. My understanding of the manoeuvre is that it is an incredibly fast and tightly controlled constant pirouetting flips. As judges, we will be looking for tightly controlled examples that should be held for a minimum of ten seconds up to a staggering 30 seconds Sustained Chaos
Set Manoeuvre 20 k=2 This  manoeuvre is based on constant forward or backward tumbles of medium speed throughout, whilst the model is steered around a remote circuit in front of the judges. Once again, the tumbling circuit is best performed at medium speed/altitude, with a medium to fast rate of tumbling Tumbling Loop
Set Manoeuvre 21 k=2 The contestant must perform a minimum of two medium sized pie-dish revolutions whilst continuously rolling the model helicopter on roll cyclic. The manoeuvre can be flown in any direction of flight and orientation of the model. Maximum points will be awarded for a constant rate of cyclic roll, motion, symmetry and altitude, with the start and finish points centred on the judges Waltzer
Set Manoeuvre 22 k=2 The contestant must perform one climbing funnel with the skids either facing in or out. At the apex of the funnel, the orientation of the skids must be reversed via roll or fore/aft cyclic and a descending funnel is performed back down to the start / exit position. Maximum points will be awarded for accurate, centrally placed symmetrical examples, where the rate of motion and altitude change is constant throughout the manoeuvre Detonator
Set Manoeuvre 23 k=2.5 This manoeuvre is a series of metronomes performed in conjunction with a constant pirouette. The helicopter muust metronome back and forth 45 off vertical with a minimum of 6 pitch reversals in conjunction with at least 1 360 pirouette in each traversal. Pirouetting Metronome
Set Manoeuvre 24 k=2.5 This manoeuvre can be entered from a hovering position or backward flight, but the start point of the manoeuvre should be directly in line with the judges. The overall manoeuvre consists of backward rolling the model helicopter continuously, whilst prescribing a symmetrical horizontal remote figure eight parallel to the flight line. The pilot can choose to roll continuously to the left or right. The manoeuvre can be entered from either the left or right hand direction and the figure eight can be flown in any direction. Horizontal Backwards Rolling Figure 8
Set Manoeuvre 25 k=2.5 This manoeuvre can be entered from a hovering position or forward / sideways flight, but the start point of the manoeuvre should be directly in line with the judges. With the model oriented tailboom vertical, a remote 8 is prescribed with a series of pitch-activated metronomes. The manoeuvre can be entered from either the left or right hand direction, with the figure eight being flown in any direction. Metronoming Horizontal Figure 8
Set Manoeuvre 26 k=2.5 This manoeuvre can be entered from the upper, lower or centre section of the manoeuvre, but the start position should be in line with the Judges. The overall appearance of the manoeuvre consists of performing one inside pirouetting loop and one outside pirouetting loop to prescribe a vertical figure eight parallel to the flight line. The pilot can choose the directions of the inside / outside pirouetting loop sections of the manoeuvre as preferred. The manouver can be entered from upright or inverted flight and the figure eight can be flown in any direction Pirouetting Vertical Figure 8
Set Manoeuvre 27 k=2.5 The overall idea is to perform a remote pirouetting wall of death manoeuvre in front of the Judges. This consists of flying a constant altitude fast moving remote circle where the model is practically vertical in the tail boom / nose axis of the model, whilst pirouetting. The entry point can be on either the near or far side of the manoeuvre, but should be in line with the judges. The rate of pirouette is left to the pilot’s discretion, but at least two pirouetting wall of death remote circles must be performed Pirouetting Wall of Death
Set Manoeuvre 28 k=2.5 The Competitor must perform a backwards horizontal figure eight whilst metronoming the helicopter on roll cyclic; the boom should remain parallel to the ground while the disk is vertical through the centre of the metronome. Maximum points will be awarded for a constant rate of metronoming, overall motion, symmetry and constant altitude, with the manoeuvre centred on the judges Drunken Sailor
Set Manoeuvre 29 k=3 The contestant must perform a sustained stationary metronome, where the orientation of the model changes on every metronome though 12 symmetrical positions to prescribe a clock face. Maximum points will be awarded for centred stationary positioning/altitude, symmetry of metronoming motion and 12 equal changes in position Big Ben
Set Manoeuvre 30 k=3 The contestant is to perform four pirouetting loops where the axis of each rotates to prescribe an imaginary globe. Maximum points will be awarded for a well-centred manoeuvre that has a constant rate of pirouette, motion, shape and change of axis for each of the four loops Pirouetting Globe
