Mach 3.5 Loki L Altitude Record Attempt Build

[watheyak]

have fun!

Tony

Good luck, Scott!

Good luck! Also care to share how many g’s your pulling off the pad? If I’m not mistaken this should be in the realm of 90 ish gs?

Good luck sir!

Thanks guys!

I've been monitoring winds aloft this week, pretty consistent out of the West, 55 mph at 18k, 69 mph at 24k today. Sharon and I will be out for Saturday, hoping to witness this flight and burn a big M sparky.
I will bring out that extra Loki motor if you are still interested....

Thanks Wayne!

Yeah all week the Jetstream has been nuts. I haven't really looked at the winds I'm Arizona, though.

Also I forget, is your Loki reload the L it the M?

And I love M sparkies.

Good luck Scott!! Looking forward to hear how it does. Im sure you will do great!! Have a great time brother!!

Loki motors are so cool.

I love the grain stripping solution Scott did there.

Best of luck

Late to the party here. Best of luck Scott!
Call if you need anything at all. I'll be available for help.
Here's some inspiration for a good flight.

L2050, same as yours. Already glued in the liner.
Built the M in a 75/8000 casing, our first Sharon's Sparkler in that casing. Burnsim is calling it 89% M1944, but we might be a bit off on that. Hoping for a 5 second burn and 15k.
Predicted ground winds are slightly lower now, was pushing 20 mph in the afternoon, now it looks more like 11 late in the afternoon.

Awesome picture Scott!

Yeah! I'm super excited about the flame to rocket ration on this flight.

Thanks Scott! I appreciate all the help.

And just so everyone knows, I've been pestering Loki Scott about details of this build for years. He's been a huge help, a wealth of information and a voice of reason.

I can't wait to see a flight report. This build has been great to follow.

It's been my pleasure to help you Scott. Projects like this one (and several others like it) are why I wanted to make motors like the L-2050. I wanted to enable people like you that could push the limits of our "hobby" materials and designs to put really small rockets really, really high up in the air, really freakin fast and bring them safely back for display to others to show them what is possible when you go to the extremes.
Thank you for this build Scott.

BTW, the further away you can get, the easier it is to get a visual track on it in my experience.

I’ve been meaning to pick up a 54/4000 case for a while. This whole thread just makes me want to even more!

Awesome build, looking forward to the flight report

The shiny threaded collar and eye-bolt are tighened with high temp Loc-tite. Getting them off might not be fun. Additionally there is a locking washer under the eye-bolt.

 

[JohnCoker]

Fantastic work all through; I love the new techniques you've pioneered.

 

[REK]

I wish you the best of luck on this flight, it is going to be amazing. You have taken the art of using composites to it’s finest.

 

[Loki Research]

Maybe I missed it earlier in the thread, but did you bring the motor case to a detail shop and ask for a wax and buff? I've never seen a Loki case so shiny before!

 

[grouch]

Well Scott, did you fly it today? I so wanted to get out to Eagle Eye today but life snuck it's head under the tent. Wish you plenty of luck man!

 

[watheyak]

Flown and recovered successfully!

Absolutely insane boost.

More later

Nice flame to rocket ratio! How did the telemetry come out?

Thanks! Too bad you couldn't make it out, it was a great turn out.

It came out great. I'll post it here soon.

 

[REK]

DAAAAAAAAAAMN, nice man, truely a beautiful take off.

 

[plugger]

Congratulations Scott, that's one HECK of a flight!

 

[watheyak]

Thanks everybody. It was a great weekend and a great flight.

There have been some questions about weights. 18oz "empty". But since the motor case is a major structural component that's a little misleading. 161oz on the pad.

Here's some data and random photos. The ones in the grass are post-flight, "out to pasture" retirement photos.

Weird things happen at 2500mph. You can see the shape of the shockwave. There's a story to why this happened, and it involved multiple F-bombs. But other than a little surface roughness, the nosecone is still structurally sound. The other side is still shiny and looks brand new-ish.

 

[Neutron95]

Any thoughts on an M1378 flight?

I still can't get over just how pretty that fin can is.

 

[rc dude]

This was an awesome build and flight! I've been slowly designing one similar over the past year using an M1378 for my L3, and seeing yours has increased my motivation to get the design finished and the build started.

 

[GrouchoDuke]

Congrats on a great flight!

How’s the GPS altitude data look?

 

[CPUTommy]

Just WOW

Amazing..there are few that I admire and respect and totally look up to as a personal bench mark. There is another thread of a rocket being build that will like yours.. just vanish.. its the skill and workmanship that comes together to produce a flight that sets a "mark" in nobody but your head...in your world.

You did it !

Huge congrats and I have to ask.. what NOW ? <evil grin>
