2014 IRCHA Speed Cup

=========================================================

 

The Speed Cup is a competition where conventional helicopters are flown one at the time (much like a Bonneville run) against the clock to achieve the fastest average speed over 200 meters. A minimum of one pass or run in each direction is needed and the scoring times are derived from the average of the two runs of opposite directions. A set time is given to each competitor to attempt as many passes as possible, the fastest time from each direction are used to compute the fastest average speed.

 

===========================================================

 

 

Where: AMA Site 3 During IRCHA Jamboree

When:  Aug. 7th and 8th, 2014, Thursday and Friday

 

Schedule:

Thursday

10am to TBD, mandatory technical inspection, qualifying***, Sportsman  and multicopter classes. Inspections will continue on site 4, TBD to 5pm at TBD area or tent.

 

Friday

9:00am to 10:00 last minute inspection (by appointment only)

10:05am Pilots Meeting

10:10am to TBDpm Speed runs, Open and Unlimited, 1st round. (2nd round for top 5 qualifiers)

TBD-2:30pm Results and pilots prize raffle.

 

Racing Classes:

Sportsman, Open, Unlimited; and Multicopter (provisional)

(No segregation of power classes)

 

 

SPORTSMAN: Commercially available helicopters assembled as boxed by the manufacturer will be allowed in the sportsman class. Electric motors and speed controllers may vary by manufacturer. Gear ratios and motor mounts may be changed but they must be readily available from a commercial source.  Nitro and gas engines may vary by manufacturer, gear ratios and motor mounts may be changed but they must be readily available from a commercial source.  Electrics are limited to 12S Li-po, 50.4v, Glow/gas engines are limited to displacement as outlined in each class.  Exceptions to the Sportsman classification are models with fully enclosed, speed bodies or with tilted main rotors. All entries must be stock looking, and must be pod and boom type, but also including the SAB standard and Speed Goblin, JR Forza, Align 700 speed, and Avant Monstro (pending release date). Main rotor speed will be limited as follows:

  • For 700 size models, maximum limit not exceed the RPM limits recommended by the helicopter manufacturer due to stress limits.
  • For 600 size models, maximum not exceed the RPM limits recommended by the helicopter manufacturer due to stress limits.
  • For 800 size models, maximum limit not exceed the RPM limits recommended by the helicopter manufacturer due to stress limits.

 

OPEN:  All helicopters manufactured in mass or limited production, and conversion kits may compete in the Open class. Modifications to the kits are allowed. Electric power is limited to 14S Li-Po, 58.8v, Glow/gas engines are limited to displacement as outlined in each class. No full bodies allowed. Main rotor must be 90 degrees to boom. Canopies must have a minimum bottom rear opening that starts from the main shaft to the tail boom (see fig 1.canopy-layout-dimensions

http://www.ircha.org/ircha-speed-cup

 

UNLIMITED: Any helicopter model including those with full bodies, tilted main rotor, and one off prototypes, may compete in the Unlimited class.  Models must be propelled by the main rotor, and cannot include compound propulsion (ie, tractor or pusher propellers). Electrics are limited to 67.2v, and glow/gas engines are limited to displacement as outlined in each class. Retractable landing gears are permissible.

Event Rules:

1. Flight Path:  The model must travel the 200 meter base course in both directions without landing. Open and Unlimited classes the model will enter the course through a 100m section (pre-stage). For Sportsman and Multicopter, the model will enter the 200m course directly but must be in level flight (not diving) an the point of entry. The flight path should be parallel to the 200m base and must never cross the designated safety boundary and must be within the prescribed altitude in paragraph 2 in order to be scored properly.


http://www.ircha.org/ircha-speed-cup

2. Flight altitude: The altitude of the model must remain below 35meters and above 5 meters during the 100m entry and 200m course. Altitudes are measure from the pilot’s base. An altitude infraction will result in a null pass.

3. Inspections: All entries will be subjected to a technical and safety inspection before entering the event. Models weight will be recorded during inspection and will be checked at random during the event.  All electrics will undergo a voltage check just prior to staging by an event official. All Li-Po cells must be from commercially available sources.

4. Time: The pilot has 3 and 1/2 minutes (4min for Unlimited class) to complete as many attempts as possible and land before the time runs out. Upon finishing the runs the helicopter will land/auto as soon as possible and re-join the staging area.

5. Flight Safety: Pilots must maintain control of the helicopter throughout the flight. If the helicopter exhibits signs of high speed porpoising, instability, or erratic flight, the pilot will be ask to land as soon and as safely possible towards the north side of the runway or over a previously designated area. No aerobatics maneuvering is permitted over the 200m course. (Two altitude judges will clear the airspace and deconflict in case of full size traffic)

6. No of Entries: A pilot can enter one and only one entry per class, up to two classes. A pilot is permitted to fly up to 2 additional entries not of his own.  Winner of multiple classes may only claim one pool prize; trophies will be awarded as earned to the model owner.

*If additional entries are desired by a contestant/company, they could be accomplished as demonstrations if arranged with IRCHA organizers. 

7. Homologation rule for sportsman and open class: Model helicopters must have it readily in the market and have produced a minimum of 30 kits available to the public no later then 30days before the date of the event. The model must be sold as a complete kit, not a semi kit or partial kit with added modifications. Whenever in question, the competitor must submit a statement from the manufacturer, or distributor to the event director to confirm availability.

8. Aftermarket parts may be used in sportsman class as long as they are bolt on replacements and do not alters the stock frame significantly or changes the main configuration of the model. Aftermarket canopies must be of similar dimensions and shape as stock ones.

9. Rotor Blades: No metal blades allowed in any class. Only commercially available blades are allowed for sportsman and open classes. Use of experimental composite blades must be approved by contest director at least 30 days before the date of the event for unlimited class only.

10. Landing Gear: All helicopters models in must have a form of landing gear and a tail skid long enough to protect the tail blades. Retractable gear is allowed for unlimited class. Landing gear for sportsman class must be of stock looks and dimensions.

11. Minimum rotor size: For safety and scoring reasons, we will only accept models with a minimum main rotor span of 1.28 meters. (>600mm blades)
