U.S. Drone War's
First Annual Multi Rotor Challenge
The First Annual Multirotor Challenge is designed to bring together modelers from all over the country and provide an opportunity to share technology, show off their aircraft, and earn the bragging rights from winning one of the many organized contest events. Be sure to join us March 23rd and 24th, 2014 for a great gathering of Multirotor models!
We currently have several events planned for the Multirotor Challenge. Here is a brief rundown of the events that are currently planned. For complete contest rules, with all of the specifications, please see the link at the bottom of this paragraph.
1. Lifting Competitions:
In the Dead Lift competition: your multirotor will lift as much weight as possible up from the ground to a height of at least 5 feet, to get the machine out of ground effect, and then hold the weight for a minimum of 10 seconds, and then set the model back down in a controlled landing.
In the Controlled Lift competition: your multirotor will have to lift off from a starting pad, and then fly a figure 8 pattern around two poles set 30 feet apart, and then come back and do a controlled landing on the starting pad.
In both lifting competitions, battery weight counts as payload. There will be 4 awards given out in this competition, two in each category. The first award will be for highest overall weight lifted, regardless of aircraft size or weight. The second award will be for the highest weight lifted as a function of the weight of the aircraft. In this category any size machine can win. For example a 2 pound model that can lift 4 pounds would beat a 20 pound model that can pick up 35 pounds, because the smaller one has a payload to machine ratio of 2.00 and the larger machine has a payload to weight ratio of 1.75.
2. Pylon Racing Competitions:
There will be two categories for the pylon racing portion of the event, Stock and Unlimited classes.
Stock Class: This class will be for basic smaller Multirotor models with a frame size of 500mm or less, measured from the motor shaft on one arm to the motor shaft of the arm directly opposite. In the case of a tri-copter, the distance from the center of the craft to the center of any motor shall not exceed 250mm. The machine can be a Tri-copter, Y6, Quad-copter or Hex-copter design with no more than 6 motors and propellers. Motor size will be limited to production models with no greater than a 22mm x 17mm stator, and a Kv value of 1200 or less. Any size props may be used, but the pitch will be limited to no more than 5 inches. All motors must be attached to the arms and no “tilt-rotor” type motors will be allowed. The only exception to this will be in the case of a tri-copter, one arm may pivot, but only for the purpose of normal yaw control.
Unlimited Class: In this class, anything goes, with a few minor exceptions, as long as it is deemed safe to fly by the contest director. There will be no limit on motor size, prop size or pitch or number of motors. Since this is a multirotor event, tilt rotor aircraft like the V-22 Osprey will not be allowed. All motors must be firmly attached to the arms of the craft pointing in the conventional direction. The only exception to this will be that one motor can rotate on an arm in a machine with an odd number of motors, but only for the purpose of maintaining normal yaw control of the model. To keep things safe in this event, there will be a maximum takeoff weight of 10 pounds, including batteries, in the Unlimited Class.
There will be a total 4 awards given out, two in each of the categories, one for highest overall point total for the event, and another for the fastest heat race time for the event.
3. Obstacle Course Competition:
There will be one award given for this competition.
4. Autonomous Spot Landing Competition:
There will be one award given for this competition to whoever has the closest landing back to the original takeoff point.
