This year's SpringFest will include a spot landing competition open to any rocket using a G or higher impulse motor. The rocket that lands closes to a pre-determined spot will win.

The details of the 45th annual Kansas Rocket Areo Modeler's Open (KRAMO) have also been posted. See KRAMO for all the details. This year's contest events are a bit different.
