2019 Rules & Registration
work in progress, subject to change without notice, last updated July 2, 2019


Competitor Entry Fee - $100
Camping Fee payable directly to Byrd's Adventure Center - $10 per person per night

Meal Information
Bring your own. There is an excellent restaurant on site but you will have to share it with 600+ rockcrawlers.

Registration is now open.

You are welcome to come as early as you want and stay as long as you want. You are also welcome to participate only in the events you wish to, you are not required to participate in any event if you don't wish to. This is all about having fun, no pressure.

Registration is a two step process and starts here:

On this first page is where you register for the event. In the first paragraph you'll see another link that will take you to where you pay the $100 (plus a small processing fee). Be sure you do both (I know it's really annoying but heh that's how it works).

Remember this is a limited attendance event so sign up now before it's full.

Pilot's Information - STOL Events

General STOL Rules:

  1. Each pilot/aircraft combination will be allowed two takeoffs and landings (or cycles) in the Obstacle STOL® event.
  2. Score will be based on the best takeoff and landing cycle of each event. (i.e. either the best set of the 1st takeoff and landing, or 2nd takeoff and landing.)
  3. Only one combination of pilot/aircraft will be allowed. However pilots may fly two different aircraft and individual aircraft may be flown by two different pilots (for those wishing to have their aircraft flown two separate times).
  4. Certificated and Experimental Aircraft of the same Class will fly together, but be scored with their type (certificated or experimental).
  5. PILOTS MUST BE TUNED TO 123.42 WHEN ON DECK. Failure is grounds for disqualification.
  6. Pilots are responsible to observe sequence and be ready to follow previous group.
  7. Sequence will be announced at the Safety Briefing.

Obstacle STOL®

Obstacle STOL® Take-Off Rules:

  1. Taxi into position as directed by the line judge, with main gear stopped on reference line.
  2. Begin take-off roll after being given the "thumbs-up" by the line judge.
  3. Take-off distance will be measured to where the furthest main wheel leaves the ground for the last time. (Rule change for 2018, Tail wheel is not measured)

Obstacle STOL® Landing Rules:

  1. Main gear tires going below the top of the pylons before they pass the pylons is disqualifying.
  2. Aircraft must come to a full stop, straight ahead, and remain until judges have had a chance to measure and clear you from the runway.
  3. Landing distance will be measured from the pylons to the main gear tires once stopped.
  4. Return to staging area for second attempt.
  5. Park after second attempt.



Pilot's Information - Flour Bombing

Flour Bombing Rules:

  1. Minimum altitude: 200 ft AGL
    1. Bombing below this altitude is disqualifying.
  2. Solo or team effort – your choice.
  3. Two passes only for each aircraft. Stay in the traffic pattern.
  4. Maintain runway heading during "bombing run".
  5. Each aircraft allowed two attempts. Final score is best of the two passes.



General Information


  1. Tie downs and chocks are your responsibility.
  3. The CAG and DEPUTY CAG will be wearing a T-shirt with CAG and DEPUTY CAG in big letters.
  4. Plane handlers will be safety vested volunteers.
  5. Sufficient porta potties will be available.

We want to emphasize that all flying will be FAR compliant. Pattern altitude is 500' AGL minimum. Sufficient VFR fuel reserves are to be carried in the event of an emergency and loitering is necessary.

"Go Arounds" are allowed as long as no wheels touch the ground. This is not so you can make practice approaches, but rather to simulate real world STOL conditions where a go around might be required. Abusing the "Go Arounds" policy will disqualify that Takeoff/Landing cycle, determination is at the discretion of the Air Boss.

If you do not make the briefing you will not fly. It will be up to the classes to police themselves, attend briefing, start-up, perform a sufficient warm up, and taxi down to the marshaling area in takeoff order. All competition paperwork should be turned in by Friday evening.

You can not leave your aircraft unattended unless it’s tied down.
