Model Forum / General / Rockets / June 2008Stealth plane
Found a drawing of what is supposed to be the "Aurora", the top-secret high-mach stealth fighter. This was inspiration for my own design. See the binaries group for pictures. I think I did too good of a job with the stealth part - it turned out it is very hard to photograph! It's made from BT20 body tubes and an Estes nosecone kit plus some cheap foam board. The leading edges of all the fin surfaces have a 1/2" piece of typing paper glued on so the foam board till not de-laminate during flight. It goes up Sunday morning on a B6 at first, then maybe a C6. It's built so that if I ever want to lose it, I can launch it on 3 engines, but I think I'll just run it on one for now. >Found a drawing of what is supposed to be the "Aurora", the top-secret >high-mach stealth fighter.

Estes did an Aurora-like kit a few years back. That had lots of foam. I have one but I think lack of suitable glue prevented me from making much progress with it. Be interested to see how yours flies.

I just got finished building a mostly foam airplane and it's all put together with white glue. Your local hobby shop should have foam safe CA. >>>White glue, epoxy and foam safe CA are all suitable for foam. Good old >>>Elmers Glue works great.

I bought and built one. Latex contact cement worked perfectly with the foam airframe shell. Dwayne Surdu-Miller >That kit would be the Estes SR-X. I bought and built one.

SignatureDarren J Longhorn http://www.geocities.com/darrenlonghorn/ NSRG #005 http://www.northstarrocketry.org.uk/ /UKRA #1094 /L2 /RSO http://www.ukra.org.uk/ It was a beautiful morning, clear with very light south winds. First thing we tried to send up was an Estes RTF model rebuilt with a 24mm enging mount. We *tried* to send it up on an Aerotech F72. The darned thing blew up like a handgrenade! This was using a copperhead (8") run up to near the delay grain. The rocket didn't even make it off the pad - the lower section w/fins was scattered and nothing of the engine could be found. Fortunatly there was no fire. Anyway - the Aurora flew like a champ on a B6-4. I'm almost blind, plus I was almost directly under the rocket, but spectators said it did a slow roll on the way up. Very nice flight. I didn't want to push my luck so that was its only flight of the day. The construction is Estes BT20 body tubes, a BT20 nosecone kit, and cheap Dollar Store foam board. I was worried about the foam coming apart, especially on the leading edges so I cut a 1/2" wide piece of typing paper, creased it and stuck it to the leading edges of all of the fins with yellow glue. The yellow glue didn't seem to want to stick to the foam, but after the paper soaked and softened a bit, it followed the curves and stuck to the paper on the outside of the foam. The paint was flat black, the cheapest rattle can paint I could find at Ace. I tested it on a scrap piece first to make sure it wasn't going to dissolve the foam core. Flat black certainly is the proper paint for a stealth plane, it made it very hard to photograph! Forgot the camera, but took some shots of it on the pad with my cell phone. Will try to post them to the binaries news group. Is anyone interested in plans for this? > The construction is Estes BT20 body tubes, a BT20 nosecone kit, and cheap > Dollar Store foam board.

Give me a few days This was totally scratch built, w/o plans so I'll have to see what the dimensions and angles are. |
