Parachute Duration Info and Plans
Parachute Duration information & plans


Parachute Duration (PD) -  Models for this event contain a Parachute for its recovery system method.  The models must stay in one piece, not drop any parts.  A big challenge of this event is to have a model that can contain a large parachute that can deploy reliably, in order to get a good duration. Some use small diameter models that boost pretty high, while other fliers use larger models that can contain and reliably deploy a larger parachute, at a tradeoff of altitude performance.
