Lambda Flights 5-8, Landings 1 & 2 

Lambda is a series of actively stabilised model rockets. The end goal for the vehicle was to perform a propulsive landing.
Lambda E, the vehicle that performed the final two flights, uses four A3 motors, two for ascent and two for descent. The dry mass of the vehicle is 200g.
The landing legs and most of the airframe are printed from TPU 98A which has excellent impact resistance, and makes integrating the rocket without breaking the airframe far easier.
