SpringFest — Saturday, March 8, 2025

  • 10:00am - 5:00pm
  • Lanterman Family Farm, Ellinwood, KS (Launch Site Information)
  • 10,000ft Waiver
  • Alternative dates: Saturday March 15 and Saturday March 22

The SpringFest launch is one of three launches this year in the Ellinwood area. This is our largest and most open launch area, which means that high power rockets are allowed at this event. We will file an FAA waiver good to 10,000 ft above ground-level. Generally speaking, this will allow up to a K impulse motor. Note that you must be properly certified, or be getting your certification, to fly high power rockets. If you would like to get Level 1 or Level 2 NAR certification, we have members that can help you with that. Please contact us if you have any questions.

This event will feature a fun spot landing competition. Any rocket flown with a G or higher impulse motor is eligible. The rocket that lands closest to a pre-determined spot wins. You can make as many attempts throughout the day as you wish.

While high power rockets are allowed at this launch, most flights tend to be of low and mid power rockets. So do not hesitate to join us even if you are not flying high power.

If there is unfavorable weather on March 8th, we are scheduling two alternative dates of March 15th and March 22nd. Watch the website or Facebook for schedule changes.

KRAMO — Saturday, June 7, 2025

This is the 45th annual Kansas Rocket Aero Modeler's Open. This will be a NAR Rocketry Competition sanctioned event, so any NRC flights will be allowed. Please see the KRAMO Page for more details.

Please note that regular sport launches are allowed and encouraged at this event. So, even if you aren't interested in the competition classes, please join us for some sport launches. Of course, once you see how much fun the competition flying is, you'll want to do that too.

This year KRAMO is planned as a one day event on Saturday. However, if the weather looks better on Sunday, June 8, we may move the event to that day. Watch the website or Facebook for any scheduling changes.
