Did a little primer sanding today.

Ordered a rattle-can mixer that attaches to a reciprocating saw.

Filled my shopping bag up at Missileworks with an RRC3, the LCD panel, and the case for the panel. Now I'm off to place my order.
can you give infor on the rattler have one for a reg jigsaw

The rattlecan shaker is called a MixKwik.

Ordered mine through Amazon but have seen it available from many other outlets.

Essentially is is a clamping system that holds a rattlecan to a reciprocating saw “blade”.

Haven’t received it yet so I can offer no review of well it works...or not.

Ah, your weight is gonna be a lot more than my Trident kit. That kit is good for about 1000 ft on 3x C6-5, with a total weight of about 275g (including motors).
My 318 is coming in at 306g without motors, the .ork file from Mach 1 states 281.373g, so I came in sort of close. I'm getting about 620 ft on C6-5's, and just under 1200 ft on a trio of Quest D16-8.

Your extra is probably glue and paint. I always update have to update my sims for those. What's the body diameter? That's a pretty big different in altitude (620 vs 1000) for the same engines and approximately same mass.

Where do you fly? Tumble recovery, which includes nose blow, is a different story on a rocky desert "field" than it is an a soft, grassy one.
If you check some of the simulated speeds, tumble recovery and streamer recovery aren't terribly different, unless you use a really huge streamer. When I sim an Estes Alpha III, it actually descends *faster* on a streamer, up to a certain size of streamer. I assume this is because the streamer prevents the "tumble" rotation that would otherwise slow down the rocket.

I built this ridiculous thing. Will it help me get my rocket out of the tree? Stay tuned.
Make sure you use some bright braided fishing line instead of clear mono-filament, as it totally is invisible at some distance so you won't know where you shot over the branch.

Unfortunately I already spooled up some monofillament, and with how annoying the spooling was, I'm not doing that again. Also, I don't fish. Can you guess?

The main tubes are 38mm (2.6"), 31 grams is not insignificant mass at this level...

The coupler between the engine mount tube and recovery tube has a baffle of two half-circles which I made from a bulkhead. I was originally going to put in a support cross member, but decided against it. The kevlar part of the shock cord should fall into one of those slots fairly nicely. View attachment 427237
Is it me or are those half moons slightly less than a semicircle? It looks like there will be a sliver of open space in the middle where hot ejection particles could go straight through.

Finally back in the shop...helped my son finish up his star orbiter build (he can't let me hold the high flight record in the house) so it will be ready for next club launch. He also built a viking out of our bulk pack, my daughter built her hi-flier (she has a HFXL, and this one is going to be a matching downsize), and I started on my baby bertha. The commanche 3 is built and fitted, just need to get decals installed.

Question: I've been looking for an Estes Leviathan kit, and the OOP ones are pricey when they come up on Ebay. Anyone purchased Vander Burn Rockets before?

They are selling a Leviathan and a Partizon clone (not to mention the HFXXL which would be awesome to add the HF collection) and I am wondering if anyone has used these kits and has had positive reviews?

I got a couple of the upgrade kits- plywood fins, centering rings... not a full kit, but no issues, great fit.

Started building one of my childhood wants. Big Bertha. Oh and commendered the kitchen table to do it.

Last night at the HARA meeting, the officers revealed that our landowner is allowing two day launches at his field! Even offered to let us store the club trailer by his house.

We're thinking of Saturday under research rules and Sundsy under NAR rules. May even see a return of Soutbern Thunder if events work out

OK, add streamer to what I stated. Still, landing on grass or landing on rocks makes a big difference in what recovery method is adequate.

Yeah, I didn't want to be all negative and nit-picky. But since you've started...

It seems to me that even full half circles might not be enough. If a straight line path is blocked only by a hair's width, I wouldn't be comfortable. I haven't build one with a baffle of this sort. I do have one sitting in my salvage box that a friend leaving the hobby gave me. It's build with three plates, and each one goes about two thirds of the way across. It's made for BT-70 (I think) and I'm sure I'll use it one of these days years.

Thanks for the info Wally! Sounds like you got what you expected and that's what I wanted to hear.

Leviathan here I come...

I've got one their Cherokee-H kits. Great kit, parts seem to fit fine. Only wish on my end is that they make one with 38mm motor mounts, as I prefer to use Loki hardware/reloads.
