New SpaceX rocket model!
Hello All,
SpaceX not only offers their $29.00 "Falcon 9 and Fairing Flying Model Rocket Kit" *here* (see: http://shop.spacex.com/accessories/...rocket-kit.html [hopefully they'll add a Falcon Heavy kit, with an optional fairing and Dragon spacecraft]), but they now also have a 32" (80 cm) tall, molded plastic "F9 Desktop Model" (see: http://shop.spacex.com/accessories/...ktop-model.html ), which comes with both a payload fairing and a Dragon V2 spacecraft, as well as a display stand. Although it's pricey ($140.00), it might make a satisfactory PMC (Plastic Model Conversion) flying model rocket, *OR*: This model's parts could be used--with no harm to them, or to their surface finishes--as "mold masters" to create RTV (Room Temperature-Vulcanizing) rubber molds, which could then be used to cast polyurethane resin (or epoxy casting resin) parts for flight models (see: http://www.ninfinger.org/models/rms...resin_cast.html ). Epoxy casting resin--which is more expensive but produces heavier, harder, stiffer parts--is excellent for casting "secondary master" parts, which can be used to create new RTV rubber molds when the original molds wear out (or to make multiple molds at once, if larger batches of polyurethane resin flight parts need to be cast simultaneously [for school projects, model rocket companies, etc.]).

The cheapest build would be to start with a F9 paper model that you can probably download for free. Resize the model to be wraps for standard body tube sizes. As for the fins I personally prefer a removable fin tube similar to Estes space shuttle or Dr zooch flame fins. Now the real challenge here for this model is to find a matchbox , hot wheels style Tesla roadster appropriately scaled, to use as a nose weight. And descending separately would be cool also.

For added reliability, the upper stage/car's parachute could be packed *below* the main rocket body's parachute, so that it would, if necessary, pull the rocket body's parachute out with it. (Sometimes dual-'chute rockets, whose components descend separately under their own parachutes, eject the payload's parachute while the main body's parachute remains stuck inside the body tube [due to a too-tight fit, ejection charge leakage, etc.]. Putting payload's 'chute below the main body's parachute ensures that they'll both leave the rocket's body tube, and while tangling of the two 'chutes is very uncommon, one or both 'chutes can be wrapped in a square of wadding [which strips off at deployment] to prevent this possibility.)

I know a lot of you don't do TRF...but there is an interesting build thread on a Falcon Heavy, so you might find it interesting... FH TRF Build thread
I thought it cool they found the fairing nose and transition used by the SpaceX kit "in the wild" and used Big Bertha nose cones for the side boosters. Might not be as pricey as 3 SpaceX kits. There are some nice AXM paper model files that could be used as a source for wraps, legs, and grid fins (note FH #1 used the smaller aluminum grid fins on the center core, and the larger titanium grid fins on the side boosters) |
