This is exactly the approach I've taken on my Hyper54. I have tubular kevlar with a loop attached to the eye as Mike suggested in his post. The plate with the eye is about 10" down from the top of the tube. But if you don't need this much space you could reduce this further...
 
Job update. Got hired by McDonalds. It’s a seven minute commute. They were really short staffed. EPB declined all who interviewed for some odd reason. Still searching for engineer jobs. Ordering a coupler tube from MAC. Firewires and deployment canisters inbound. I’ll probably start making more progress on this in a few weeks.
 
Congrats on the job. My daughter works for Maccas. Really didn't like the idea but once she started working there she loved it. Opportunities for progression if you want it. Great for learning how to deal with the general public and seen by some employers as a good thing to have on the resume. It will do my daughter until she finishes her degree.

I drilled it out to quarter inch and put one of his eyeloop threaded bolts into it.

Job update. Finished training at Hytrol for Design engineer. Conveyors have been interesting departure from rocketry to say the least. Moved twice lately. Been looking into launches at HARA and Sayre, Oklahoma this fall. Either way it’ll be a long drive.

Placed an order for Cotronics 4525 IP tonight. Got side tracked and blew $1.9k on German firearms lately. Lmao.

Hoping to order some more stuff and get back to building it. I had to put rocketry on hold while renting a corporate suite because that had wayyy too nice floors and I definitely didn’t want to ruin it with epoxy.
 
Ordered 30” IRIS Fruity ultra compact fruity chute for L motor flights, Fruity chute 12” drogue. 40 ft of one bad hawk recovery harness, Two additive aerospace 54mm FARG.
 
E512036B-43D7-402B-B44C-DEB1BEFBD2AD.jpeg Goodies from Fruity Chutes arrived. Still waiting on other stuff.
 
Ordered a MissileWorks RRC3 sport, data usb cable thingy, nomex, and shear pins.
 
I sense a build on your near future!

Yeah it’s finally coming together. Need OneBadhawk to unpack from LDRS and start shipping shock cords again. Still gotta figure out a solution for internet wifi router and possibly get TeleBT or Laptop.

Attempting to get flight ready by October.

Other misc stuff, need a better scale, electric drill, sandpaper, switches, and etc.

3031689B-A9B5-4B3E-9E05-063AB45D573A.jpeg Finally it’s a proper build thread again. Just Cotronics 4525 IP the bolt to coupler tube to nut to coupler tube plate. Cut a coupler tube in half of its original length. Flipped coupler tube plate around so basically it physically can’t come out. Embedded 29.5” from tailpipe. Epoxied nosecone shoulder on and also the AvBay ring. Noticed the av bay eye bolts could be loosed by hand so I epoxied those as well because I don’t want a twisting shock cord undoing the recovery hardware in flight. Still need wireless router for avionics support, switches, misc avionics bay hardware, and etc. Did a mock up before I epoxied everything. Tired.

For those of you who haven’t worked with Cotronics 4525 IP it’s like a creamier version of rocketpoxy and way less bubbly. I like it so far. But the work time is thirty minutes. Second note is 4525 IP won’t gag you like 4700 will.

Nice work Andrew. Now lets see a flight report...
 
Been awhile got busy again. Trying to get vacation off next week and get it up in the air at HARA on Dec. 21st on a J. Really gotta get a laptop and net set up this weekend. Then work on av bay/ground tests/etc

Got a L1000W inbound tomorrow (this one motor won’t fly at HARA). Other updates ordered Loki 54/2800 casing stuff for L1040LR. Ordered Binder Design switches then the Aerocon screw switches. I’ll see what I like better this weekend/next week.
 
Altitude geusstimate?

Memory is a little fuzzy. Still need to set up pc at home. I wanna say it sims about 7500ft on J250 DMS which would fit under hara’s waiver with a large safety margin.

The L1000W was about 18,800 ft, and the Loki L1040LR claimed like 25k ft in OR and M2.4 which I think is a tad hot spec. Just doubtful it would really go 25k ft.

For my practical purposes the L loads would have to fly out of Sayre, OK or elsewhere with high waiver like next year.

Alright enough moaning on my end. I bit the bullet and blew $710 on a basic HP laptop, eero WiFi thingy, and a modem and a four port usb extension and E cables. Gonna try to get net set up this evening and program some altimeters.

It’s funny I don’t care blowing $275 on motor but when it comes to electronics idgaf. Laptop was $400 ish and not mad about that price. This thing will primarily be a base station for rockets so it doesn’t need to be the fastest unit or insane memory size. Surprised to see they had solid state drives.
 
TeleGPS works going to test it slightly more tomorrow. Forget I had it on 434.550 MHz lol. Just wish those Aerocon switches were here.
