The TSP L-4 engines are small engines designed for the propulsion of rocket gliders, with low thrust and very long duration, 18 seconds. Same size of Estes or Klima motors, 18 x 70 mm.
Their thrust is so low that they are only suitable for aircraft models that fly thanks to their wings and only horizontally, and it is not sufficient for vertical flight. By the standard model rocket engines coding system, their type is D0.9-P.
The TSP engines are a perfect replacement of Rapier engines of equal characteristics, and which are now no longer in production, and the famous old Jetex engines that no longer exist since the Seventies.
For suitable glider designs, information and advice, please visit Jetex.org, which specializes in this fascinating field of flying modeling.
