Well, haven't been doing any flying or building, it's the height of competetive shooting season, been doing lots of that, went down to the evergreen aviation museum to see the new firearms exhibit they opened, the son of the owner has a very extensive collection of full auto lmg's, and a lot of other neat things, anyway, snapped a few photos of some planes, so thought I'd share them, and some rockets. They have added quite a few new things in the space center, and they had one of my favorites, a delta dart now outside next to the dagger, that was a nice surprise, as well as hanging up the X-15 mockup.

I've been working on an upscale Mach10 boost glider that Centuri made, I used a cruciform foam fuse and slid the body tube over it, my thrustline is right up the center and the wings are in the center, instead of the offset thrustline, canted upper fin and low wings of the original, but it keeps the look pretty well.

Flew great, glide wasn't really long, but it was very docile. Fuse was flow-through to reduce drag and I didn't need to drop any balast, I kept the top fin level with the wing and just used reflex to keep the nose up during glide.

Here is my main plans page. These were primarily designed for 24mm rocket boost and glide recovery. However with proper "prop" clearance and modification to install a pusher motor, they should work fine as pusher parkjets. Several of them I have flown this way.

For rocket boost, I prefer the Aerotech RC 24mm case and E-6 RC reloads exclusively as this gives an 8 second burn time, gentle boost, and they are very controllable. I do not have to shift any weight for the CG shift, I use a slightly tail heavy launch condition and slightly nose heavy glide and it works perfectly. Use of heavier motors or ones with less thrust may result in unstable or low boosts. I also use/recommend a 6 foot 1/4" launch rod or launch rail. I've made a simple adapter out of an aluminum tube with a hardwood dowel glued inside with launch buttons on either end, that I can slide into my 1/4" launch lug to adapt these to my rail as well. The rail doesn't flex/whip as much.


Reminder that these were scanned full size, but printers normally cannot print to the edges, normally a printer will shrink the image and put some border around it, this will yield a smaller than original print and may cause mis-alignment, make sure you turn off page scaling in the printer before printing, and that there is no scaling or auto-expand or fill to the sheets and that you print without borders.

Most of these will fit onto a single sheet of 27"x39" 6mm depron, a few may take two...Continue Reading
