Spadroon motor testers needed!
 

Hello All,

The Spadroon jet motors, which are single-use, solid propellent rocket motors for propelling Jetex- and Rapier-type F/F (Free-Flight) model airplanes, are ready for Beta testing, and Dr. Edward Jones, their developer, is seeking modelers to evaluate them (I have provided his complete contact information below). The Spadroon jet motors, like Dr. Jan Zigmund's Rapier jet motors, are low-thrust (15 grams), long-burning (20+ seconds) motors that resemble black powder model rocket motors. Dr. Jones is also interested in hobbyists' evaluations of the Spadroon motors for non-flight applications, such as model cars and model boats (Jetex and Rapier jet motors were/are also used to propel such models).

Dr. Edward Jones (e-mail: rocketscienceinstitute@gmail.com - I've included his postal address below) is the founder of the Jet-Ex-Press Jetex/Rapier discussion forum on Yahoo.com (see: https://groups.yahoo.com/neo/groups/Jet-Ex-Press/info ). He is a retired propellant chemist from Aerojet General, and he was on the team that developed the solid propellants that were/are used in various stages of the Polaris, Minuteman, and Trident ballistic missiles, as well as in the Genie air-to-air rocket and many others. He also worked on the long-burning (9 minutes!) solid motor that powered the AQM-38 target drone--this guanadine nitrate motor was, literally, the largest and longest-burning Jetex motor ever made--and it was even reusable (just like the English Jetex model jet motors)! Also:

The Spadroon, which is his own version of the Czech-made single-use Rapier jet motors (see: www.rapier.cz and www.jetex.org ), could also--with the addition of a clockwork or electronic recovery system deployment timer--power low-thrust, long-burning, boosted single-stage model rockets (including scale models of the WAC Corporal, Aerobee, IRIS, Boosted Arcas I, INTA-255, Skylark [the Cuckoo-boosted variants], the Skua, and the Petrel), as well as provide secondary (horizontal flight) propulsion for boost-gliders and rocket gliders. In addition:

Below I have included his Rocket Science Books website's URL (his book outlet, which offers reprints of rare rocketry and jet propulsion books), below his postal address, which is:
