Rocket & Pulsejet B/Gs!
New model pulsejet engines have become available (please see below). Like ramjets (which are much harder to make work in model sizes), model pulsejet engines could power model rocket-boosted scale models of air-breathing target drones, RPVs, and missiles (such as the Orbital Sciences GQM-163 Coyote ducted-rocket supersonic target [see: http://en.wikipedia.org/wiki/GQM-163_Coyote ], Canadair's [Bombardier's] Bullpup missile-like, turbojet-powered CL-89 and CL-289 reconnaissance RPVs [see: http://en.wikipedia.org/wiki/CL-89 ], etc.) Such models could be built and flown as R/C or F/F (Free-Flight) scale boost-gliders. Now:
Hobby King is offering new-production "Red Head" pulsejet engines (see: http://hobbyking.com/hobbyking/stor...ion_System.html ), with ignition systems. The Red Head pulsejet runs on ordinary gasoline. Also, an eBay vendor is offering valveless pulsejet engines (see: http://www.ebay.com/sch/i.html?_trk...cat=0&_from=R40 ) that run on propane. While such engines are usually used to power C/L (Control-Line) and occasionally R/C (Radio-Control) model jets, there is no reason why suitably large (with good gliding performance) F/F (Free-Flight) pulsejet-powered models could not also be flown safely. Scale models (or scale-like models, with larger wings) of pulsejet drones would make good F/F pulsejet models. Also:
Below are five (5) links to material on two pulsejet-powered target drones--the Globe XKD5G and the Globe KD2G Firefly. Scale models of both drones would be very easy to build using model rocket body tubes and nose cones, and ducted Rapier or Jetex (or EDF) jet motors could be installed inside "just for looks" dummy pulsejet engines on the models. Actual model pulsejet engines could also be used. Here are the links, and also two references to information on the XKD5G and KD2G drones:
 Norman J. Bowman: "The Handbook of Rockets and Guided Missiles", Perastadion Press, 1963
 US Navy: "Model Designations of Naval Aircraft", 1950 and 1951
I hope this information will be helpful.
