Don't forget to check out the 29mm version, using larger SEMROC components...  The same basic plan for the BS2 can be enlarged the same way...

New Plan -- Czech ALFA, Estes components
This is based on a message from Roy Green over on OldRockets about his acquisition of an original 1966 Czech ALFA kit.
The BARCLONE version uses the BMS version of the BNC-50J nose cone, which is reasonably close to the nose cone shape seen in a photo in MRN v6 N2 (page 6). I chose the BT-50W body tube (9.5"), and created fins that are similar. This version uses a standard 18mm mount. I sent Roy a message that he should measure, scan, trace, and photograph his kit for YORP...

New Plan -- Star Ranger
I thought of this design as an early development prototype to the Estes Andromeda and Alien Explorer classes of starships. Not as flashy as those later designs, as this is intended to be an early "technology demonstrator" for the systems they would later use...
All SEMROC components this time... Specs are as follows: Length = 40.2" Fin Span = 8.1" Weight = 3.03 oz Altitude = 330' Deployment V = 6.75 fps Recovery = SEMROC 20" parachute Motor = C6-3 Do not use any other motor for this model!

New Plan -- Regulus
This is a very rough prototype simulation of a design inspired by those beautiful Sunward/Canaroc models...
Surprisingly, RS allows me to simulate most of the design, although it won't draw the nose and tail cones on the non-centerline tubes. I hope Apogee is looking into this for their next version. Try to imagine those cones in-place when you look at the 3D image. This design will be prototyped and flown before a PDF is available, but I wanted to put this sim out here to get some feedback...

Very pretty, Craig. It's nice to see your "Scrounged" designs getting more adventurous. I would caution that the tail section of the Regulus here has quite a bit of feel like Rockitflite's new Odyessy kit.
Keep on chugging out the new designs! By the way, the latest file you sent me on my "starter" model with the twin tails? It's really cool, but it's even further from the look I'm going for. Why don't you change the name and post the twin-tail here? Later, EV

I'll make some changes to the Regulus, since I wasn't trying to "copy" anything. This was just a "first draft" sim... Quote:
Are we talking about the swept-tip version, or the flat-tip version?

Regulus
Here's an updated version of the Regulus, with minor changes to the tail area. Be sure to check the flight specs on the RKT file...
Small sample: Max Alt = 670' Deployment V = 1.1 fps Motor = C6-5

Regulus -- V3
Here's yet another revision to the tail section. I gave the pylons some curves to break the sharp edge look of the earlied versions...

EVModels Nightwing
Quote:
DOH!   I know which one... Here is a new design from EchoVictor, which is a derivative of yet another model still under development... Simple to build, nothing very complicated, which are usually the qualities found in a very good model. Performance is excellent on the A3-4T motor, reaching 430', and deploying at a gentle 5 fps.

Honestly, Craig, give yourself some credit. This design has morphed so much from my original vision that it has become its own design. So really, it's the Craig McGraw/BARCLONE Nightwing. If you want you could say it was inspired by an EVR (EchoVictor Rocketry - it's the name I'll use once I get the ball rolling early next year) design. Later, EV
