High Power Season is Here

Posted: August 24, 2022

KOSMO typically schedules about three launches each year at our flying field near Ellinwood, KS that allows for flying high power rockets. The next two scheduled launches are planned for this field. First is the Final Frontier Fun Fly on Saturday September 10th. That will be followed by Rocket-tober Fest on Saturday, October 8th. There are alternate dates as well if the weather doesn't cooperate. See the Events page for all the details.

At both of these events we will have an FAA waiver good to 10,000 ft above ground level. That means any high power rocket can fly up to that altitude. The size of the field generally supports rockets using up to a K motor, though certain circumstances may allow bigger motors as well. To fly high power, you must have the proper NAR or Tripoli certification. We will be flying under NAR rules, so no experimental motors. If you are interested it getting your Level 1 or Level 2 certifications we will have people on site that can help you do that.

Of course, it isn't only about the high power. There will be plenty of the small model rockets and mid-power rockets flown too. Unfortunately, due to dry weather, we are going to have to pay special attention to flying conditions and/or burn bans. Watch for further announcemnts as the launch dates approach.

KRAMO is Here

The KOSMO flying season is starting this month, with Spring Fling, one of our three high power launches at our launch site near Ellinwood, KS.
