UMMARY


The launch vehicle is designed to reach a mile


It contains a Lateral Flight Dynamics (LFD)
Payload


Designed to test dampening of longitudinal roll with
rollerons


Aileron Deflection Package (ADP) is will induce a roll


Rollerons

dampen the roll


LFD fins mount
rollerons

and measure the roll rate
