Helicopters

Instructions for remote competitions:

 

Students will compete on their own and video the event prior to tournament day, between Wednesday, April 28 and midnight Friday, April 30 Eastern Daylight Savings Time before the tournament to allow some time to correct any transmission issues.  To ensure teams do not start before the agreed time, we will provide a ‘code’ word to be posted that morning for all teams to see.  Said code word to be stated/shown on the video.

These videos with supplemental information as needed (eg flight log) will be e-mailed to me, the event supervisor, or uploaded to a suitable site (eg google docs, Youtube) and a link sent to me to download info.  My expectation is that in addition to information on the devices to ensure compliance to the rules, the teams would show an 8-minute time with flights called practice, official, etc, as per the current written rules.

 

  • All written rules apply, except that the teams will be providing measuring devices and doing the measurements on video to demonstrate compliance.  Timing will remain the responsibility of the Event Supervisor based on video provided.
  • Teams will provide one continuous video with the following content:
    • Show conformance to rule 3. Construction Parameters:
      • Video the helicopter from multiple directions, (at least side, top, bottom, front quarter, rear quarter), try to keep the helicopter in good focus and as close to full frame as practical so I can evaluate conformance with rules 3.a,b,c & i and evaluate bonus rule 5.a.  If you are claiming a single bladed rotor, clearly demonstrate how that rotor is powered, provides lift and rotates independent of any other rotor blade.
      • Demonstrate helicopter mass is within the prescribed range (rule 3.e) using a scale with resolution to at least 0.1 gm.
      • Demonstrate all multi bladed rotors are within the prescribed diameter(rule 3.f) using a rule with resolution to at least 0.1 cm or a go/no go gauge, show the gauge is to correct dimension.
      • Demonstrate  all single bladed rotors are within the prescribed radius(rule 3.g) using a rule with resolution to at least 0.1 cm or a go/no go gauge, show the gauge is to correct dimension.
      •  
    • For rule 4. The Competition:
    • Flight logs as prescribed (rule 4.c) may be provided on the video, please video clearly, full frame, for approx. 10 seconds.  Alternatively, they may be provided as a separate file along with the video, Excel, Word, plain text or PDF format.
    • Show the ceiling height of the room is within prescribed limits (rule 4.a)
    • The flying portion of the competition (rule 4.b,d,f-h,j) should be videoed as if the team were competing in an in person event.  I recommend it be after all the previous steps.
      • Clearly show all helicopter launches, follow the helicopter through the flight and end of flight.  Try not to lose the helicopter during its full flight period.
      • Make sure the student can be heard declaring if practice or official.
      • Feel free to show your timers, but the official times will be made by the Event Supervisor based on the video.
