Hi all Title self explanatory - looking for a vendor that sells ballutes. 12" / 18" / 24" are the sizes I have in mind.

So...I've successfully installed the AltOS software, hooked up my laptop to the EasyMini with a USB cable I know works...but when I power up the EasyMinis neither is visible on the Configure Altimeter function, or any other function on the software interface. On power up (I switch on the...

Evenin' all... My wife recently bought this deodorant stick. Naturally, as one does on these occasions, I pictured it flying, possibly with a single motor, or maybe a cluster, with fins as necessary. I was wondering if there's any record of, or plans for, such a vehicle? The shape's pretty...

Rest in peace Colin Cantwell (1932-2022), who worked on both Kubrick's 2001: A Space Odyssey and the original Star Wars Episode 4. I have on occasion wondered if the Nike Smoke, with its long snout, was an inspiration for the X-Wing, but apparently not - it was a game of darts in a pub...

I have just acquired some very well preserved second-hand Aerotech casings - 54/1280, 54/1706 alongside a 54/852 Dr Rocket's case, which I understand is fully compatible with AT loads (newly available here in the UK). Can anyone tell me any of the history of Dr Rockets ? Are they still around?

What do you use to clean up your quicklinks? I don't mind the discolouration so much, but the crud build up is clogging the threads.

Hi all So this is just a 'please confirm' I've done this right' sort of thread: Checking a 38 2 G White Thunder load the nozzle was loose and the grains slipped out, luckily hitting something soft. They're undamaged by the drop but I haven't disassembled this motor before. Now I'm putting the...

A grateful acknowledgment to Jim Amos at Missileworks: as posted here a while back, after a couple of flights I had a problem programming my RRC3 with the mDACS dongle. After a trouble shooting discussion with Jim Amos via the Missileworks website he sent me a new one free of charge. Great...

Hi all, Ok, so on previous occasions I've programmed my RRC3 using the RRC3 and USB-IO powersource and the mDACS software with no problems. However, this time, when I connect up the USB-IO with my laptop, switch on, and launch the mDACS app, no 'Active Comm Port' appears in the Comm Link field...

Interior shot of a 4" payload bay: I'm puzzled by the blistering visible. There are no corresponding creases or dents on the outside surfaces. Thinking back this component has been through 8 flights / deployments. The sheen is from the sealant I use to make clean up easier. Structurally it...

Hi All I've just inherited a CTI K445, date stamped 2007. It's still completely sealed in its poly packet and I'm au fait with the motor's provenance, so I'm pretty comfortable with flying it and looking forward to doing so as soon as feasible. However, since I've only been involved in HPR...

Why do some CTI 54mm rear closures have the two holes, and some don't?

Hi all So is any increase in compression or shear strength gained by painting Loc tubing (stripped of glassine) in thin CA? Stay safe,

Hi all Quick question - for an Honest John type nc/airframe combination, where the NC dia is wider than the aiframe, is there an optimum location for an AV bay with static ports? For example, my understanding is that static ports should not be placed immediately behind a reducing transition. Is...

This isn't exactly a build thread but a quick look back at a recent build... As one does occasionally, I decided I needed another rocket and found myself mysteriously drawn to the 3" dia / 38mm MMT combination. There a couple of reasons for this - (1) I keep a log of my flights and realised I...

Hi all, So one of my ET Quantums (or should that be Quanti..?) had a bit of a violent knock a while back. There doesn't seem to be anything visibly wrong, and I get the wifi connection no problem (see pic), but it won't arm when fully hooked up to charges etc. When I try to run a test it runs...

Hi all Wondering if any one has successfully flown a Stratologger CF on one of those little Turnigy Nanotech 300mAh 7.4V LiPo batteries..? Interested in any experience anyone can share. Thanks!

Weird thing - I just tried re-installing the TC app but it appears to be unavailable ('not found') on Google Play Store. Likewise follwing the Google Play link from the TC website. Does anyone know what's happened to it..?

Don't know if anyone else has done this but I made this switchband for a 3" Av bay I'm building by layering up neatly cut strips of 150gsm / 90# cartridge paper. pasted together with aliphatic resin glue. Sealed the edges and left to dry, it's very tough. Accurate measuring and cutting (used a...

Has anyone compiled a list of propellants listing relative ease of ignition / pressurisation time ? I'm thinking if such a thing existed it would be useful in selecting sustainer/airstarted motors. I did a search but couldn't see anything. If not, perhaps people would care to share - either hard...
