Featured Flight Guidelines/Application

What is a BFR?

Lets face it, a BFR is a Big Flipping Rocket. The biggest rockets you’ll see flown at Spudnik we call BFRs. They fly on L – O motors and are usually very heavy. They carry multiple electronic devices to control parachute deployment. We need to review what you are bringing if you are planning to fly a BFR.

Do I have to register my rocket as a BFR?

Yes, if you plan to fly a rocket with an L or larger. NSL is a big event and we need to have a good idea what to expect to support them and you! If you show up with a rocket that you have not pre-registered, your flight will be allowed only at the discretion of the LCO.

General Guidelines

The form allows for uploading a RockSim or other simulation files. Please provide this as it helps the BFR team understand your rocket. BFR flights present greater recovery challenges than other flights, make a plan for recovery before your rocket is on the pad. Look at the aerial photo of the field and know where you are. Take a phone, take water, a vehicle if necessary to retrieve the rocket.

Local Rules

  • SLVROC requires two (2) altimeters on board all BFR class rockets. Each altimeter is to fire a separate charge for both apogee and main deployment.
  • Each altimeter must have its own power supply. Some new altimeters are capable of programmed multiple events as “back-up”. These do not meet the requirement for redundancy.
  • The field is open to O motors. However, Registrants intending to launch motors of N and O impulse must contact the event director through NSLWest@nar.org more than 60 days ahead of time to discuss logistics.
