The Durham launch site now supports limited high power launches in addition to model and mid-power rocketry. Please see the section below for the restrictions we place on high power launches.

Model and Mid-Power Limits

Max Takeoff Weight - 1500g (3.3 lbs)
Max single motor average thrust - 80 N
Max single motor impulse - 160 Ns
Max total (Cluster) motor impulse - 320 Ns
Max propellant weight - 125 g
Altitude limit - 3000 ft

High Power Rules and Limits

Maximum loaded impulse : < 640Ns (that's one I motor)
Maximum altitude : 2000 ft (single deploy) and 2500 ft (dual deploy)
ALL high power flights must have PRINTED simulation results
ALL high power flights will be RSO'ed by a Level 2 or 3 CATO Board member
No high power Sparkys (due to fire hazard and noise)
WE WILL NO LONGER BE PERMITTING HIGH POWER ODD ROCKS (Pyramids, Stealths, etc)
