Monster Projects for Argonia LDRS

Starting early on some pretty large projects for LDRS next year. I haven’t been to Argonia for 20 years so there is some excitement in having that large of a field and waiver available.
I don’t know about waiting over a year so one or two of these may also end up at Red Glare for a first flight.

I have had some ask about build threads for the 12” diameter Bertha I flew this year so I was going to use this thread for this years projects and for anyone else whom wants to participate.

First up will be my 12” diameter upscale of Quest’s Quad Runner kit
Has 4x98mm motor mounts.

Second will be a 12” diameter Aerobee 150 with 3 x 98mm mounts. Plans are to fly with 3x Aerotech N2220 Dark Matter motors.


Let’s get to work.

Awesome, I'll be there to watch 'em fly.
Where are you getting all this 12in tubing?

I am defineltely watching this. Please post a video of the launch. Those N2220s are beautiful

Looks fun, I'll be watching this one. How do you get those motors to light reliably and simultaneously?

I use thermite or BKNO3 pellets for clusters.

Oh my! How exciting keep us updated as the project moves along

The 12” diameter Quad Runner is coming along nicely. Painted and decals applied. Clear coat next

Simply wow!

Is that rattle can paint or spray gun? Either way, very impressive.

Nason automotive paint from a spray gun

Assembled my main bulkhead. The G12 couplers are much tighter in these larger tubes so some sanding is required. I like to use 1x2s in my larger assemblies and then 6’ tow straps for my shock cord attachment.

Yes where did guys get the 12" tubes?

Bonded main bulkhead coupler, clear coated and slid together, almost done this one and on to the next big project

Holy moly! Do you have any performance specs for these beauties?

wow.

Beautiful build. Great workshop!

What material is used for the fins, and what method/adhesive do you use to bond aluminum CRs to FWFG tube?

The fins are 3/8” thickG10. I use 3m panel bond adhesive for all fiberglass to fiberglass and fiberglass to metal joints.

It must be top sercet where they get the 12" tubes?

The usual suspects: Curtis T

Just kidding that is what I was guessing. I sure wish he would get some nose cones made in any sizes.

Nice rockets. The nose cones are gorgeous.

Yes he has very nice cones. But seem to be hard to get lately.

He is currently making a mold for a 11.675 5:1 ogive and eventually going to do a 5:1 conical.

Any particular cone you are looking for?

Haven’t posted in some time (some have made it to Facebook) but allot of progress is being made on various projects.
Have done much work on the 6” O motor with successful static fires
But now we need something to fly it in:




A 12” diameter Estes Citation Patriot.

Also the 12” diameter Aerobee 150 is coming along for 3 x Aerotech N motors

The Aerobee is looking great! Being a fan of the type, and having just scratch built a 4” Aerobee 150 myself, I’d love to see more photos of the build if you have any!

I saw the thread here ( if that was yours) and it came out fantastic.

I can gather some pics, I have less than usual for these builds but have some and will take additional



Will get more photos as I finish the avionics bay this week and hopefully start paint next

This is amazing stuff!!

What have the neighbors said about your rockets?

If it is the recent build thread, then it was mine. Thanks!

What are the final dimensions of the beast? It looks like it should be a good flight!
