Have had a 12 pack of D2.3 reloads for a while and wanted to do something a little different and fun for this interesting 18mm reload.
Have always liked the Black Horse spaceplane concept from a few years ago and decided to size a model for the 18mm D2.3. This model is very much semi scale and not a detailed model of the concept. (In the RC world, we call this sport scale or fun scale)
The 3-view drawing attached is easy to find on the internet, as are several articles about Black Horse, which has more or less morphed into the Pioneer Rocketplane.
Started it a couple of weeks back and decided last week to finish up for the NARAM sport launch.
Picked a length of 20.5" and a span of about 19.5". After doing a lot of profile models lately, I wanted to do a full fuselage. Flat sides and rectangular formers were sketched up. After cutting out the cranked delta wing from 6mm Depron, the fuse plan was laid out on the wing center section and built up on top of the wing with 3mm Depron fuse sides and 6mm formers. Wing spar is 1x6mm flat carbon strip.
Laminated 2 layers of 1mm Depron around a BT60 tube so that it would take a curve. Hit it lightly with a heat gun to set the Depron and speed the glue cure.
Just about complete. Still need to add the ballast, attach the curved upper fuse panels, do some foam block work for the nose and canopy area
Current weight is 3.4 oz, with the 18mm case and radio gear, but without the nose weight, nose blocks, pushrods and decals. Goal weight is 6.5oz or so.
Even though 6mm Depron is no longer available, I think this model could be built with the other softer foam sheet options out there, adding a touch of reinforcement here and there.
More as it develops!
