Be aware that publication of hardcopy submissions may be delayed until it can be keyed in. Computer files may be submitted on CD or DVD, in either Macin- tosh or PC formats; always enclose a hardcopy printout as well. Save the article as a plain ASCII text-only file. You may also save it as a word processor file to preserve formatting (save using an older file format to make file conversion easier for us). Photographs can be submitted as prints or 35 mm slides. Prints should be glossy, color or black & white, no larger than 8x10 and no smaller than 3x5. Always affix your name and a caption to the back of the photo. Do not write directly onto pho- tos; use tape or post-notes. Ship photos with the faces protected. Digital Images require at least 150 ppi at the final size and cropping used in the magazine. Higher resolutions are pre - ferred. Minimal image compression is preferred. Images should be in separate files, not embedded in the article file.

Be aware that publication may be delayed if we must prepare publication quality drawings from hardcopy. Computer generated graphics are preferred in vector formats, such as EPS (encap- sulated Postscript), rather than bitmapped formats. Contact the editor about file formats to use.

I recently purchased the new Estes 1:200-scale Space Shuttle. is is an RTF kit, but you do have to tie on the parachute and insert balancing clay into a slot on the un- derside of the orbiter before your can fly. e orbiter is molded from styrofoam (or some- thing similar) and returns by glide recovery. e model is stabilized in flight by plug-in clear plastic fins, which are the same design as used on the Estes SLS kit. One of my fin units was warped, but I was able to correct this by heating it with a hair dryer for a min- ute and applying some judicious bending. You assemble the display stand by insert- ing a clear stalk through the base and secur- ing it in place with a clear plastic screw-on cap. is cap is the same shape as the opaque white plastic engine retainer of the model, so it can serve as a spare if you lose your engine retainer. Nice. e External Tank's plastic nose cone has an clever feature that I hadn't seen before: e attachment loop that you tie the para- chute lines onto has a downward extension that prevents the parachute lines or shock cord from sliding up the side of the loop. is will help prevent the lines accidentally sliding up there and making the nose fit too tight, helping prevent a non-deployment di- saster. Very nice. I haven't flown the model yet, so I can't say how well it works. Here is a picture of it on the end of my 1:200 scale model shelf next to the Estes SLS model. ★ ★
