    Doorknob1 Vs. Doorknob2 variance

    I didn't realize until looking closer at the material source. My father is a published historian and I'm a struggling fiction guy and know the problems of maintaining a hold on material once it's out there. I sent a note to the poster about the pics and hopefully they will be kindly removed. The...

    Doorknob1 Vs. Doorknob2 variance

    Thank you guys for digging deeper. Looks like my linked site is incorrect and Estes is incorrect. A 3" 29mm DK2 would be quite a fun project. Might get 1kg empty with all electrics.

    Doorknob1 Vs. Doorknob2 variance

    I'm trying to find all I can on the actual scale measures of these things, and to be honest, I'm not finding much accurate info. Looking at the estes release of the Doorknob this year, I'm seeing their claimed 1:12 scale, but listed at just shy of 26 inches tall.....one of those numbers is way...

    A Big And Bizarre Drone Mystery Is Unfolding In Rural Colorado

    Guy Fawkes tried to blow up parliament, a Protestant controlled parliament with King James, who at the time was creating the new King James bible. Fawkes was in hardcore disagreement. The anonymous chosen Fawkes mask is a show to government, don't try to force my beliefs and way of life. Was...

    Props to Stickershock23

    Absolutely top notch guy! Enthusiastic to get a good job done. He worked with me on modifying an upscale set, and even made a new page for it on his site becuase everyone else was doing the retro paint scheme. I wanted something a bit more exciting and colorful. BT-80 was my size (60% up on the...

    New computer: thoughts? input? avoid? recommendations?

    I just built an enthusiast desktop. Some takeaways: Just get avryzen 3600x. It'll last you a decade at least. It's fast, clocks itself up and down appropriately, and the new chips today are so efficient, you don't need water-cooling unless you really plan to up voltage and clocks but honestly...

    Estes gives you the chance to bring one rocket back. What would it be?

    Either the Maurader or Cobra 1500. Both from my 5th grade gradeschool builds in early 80s.

    Technique building history?

    this is getting epoxied in, jbweld on the mount tube and tw fins jb to mount tube, then epoxied elsewhere, epoxy clay filets. itll be able to take abuse, which is what its for. RMS hobby reloads and occasional 29/360 shots. For white glue, Titebond3 is really good stuff and gets into the pores...

    Technique building history?

    It's late 80s early 90s. It's got age on it and the guys collection had quite a lot of vintage Estes. A teacher who retired about 6-8 years back

    Technique building history?

    I drilled a small hole in the rear, saw the shavings and couldn't tell what it was but it was thin. So I was worried. The mount tube also had a few blisters inside in the exhaust residue, so I just got cautious and removed the mount. They were phenolic rings, plastic like. After removing them, I...

    What did you do rocket wise today?

    Restoration of a loved...and we'll used, quarter scale 29mm Patriot. Inside cleared Funenough to slide in a new mount and new fin slots cut.

    Technique building history?

    Pictures will come later this week when i get home. By all research it appears in exact dimension to the Mad Cow patriot missile (like on apogees page) but with older build parts in 29mm mount size and wood strips up the sides in white, like their picture shows. The retention is pretty much...

    Technique building history?

    So I'm looking at near 40 years or so. I'll poke a bit into the rings and see how solid they may be.

    Technique building history?

    I was gifted an older 29mm mount 4" build. Retention of the era is masking tape, and recovery attachment is by looped metal cable to flat half inch elastic strap. On tube fin mount. Not plywood ring motor mount...this is old school by appearance to me. (Of course I don't know how old is...

    Estes/HL: ESAM-58 My take on it.

    The market is purely Hobby Lobby for this, which is more youthfully oriented in their rockets. It's a budget deal as well for Estes which was in Danger of loosing HL. A D12 on this would be over 1000 ft. E12? 1400+. I e12d a loadstar upper stage and hit 1200 with Cam and altimeter in it. I can...

    Super Big Bertha- Custom build: a question about "Too much" power...

    I'm planning a build of one as well, dual 29 mount in in my parts pile, but hesitant over the thin wall bt80 tubing. Because the potential exists to run a dual g40....and thats over 2,000+ feet and chute release territory. Besides, setting them both off and what not experimenting... I think some...
