A bit of the good, the bad and the ugly, but hey... prototyping is part of the process.

Firstly, my Estes PSII launch controller is the biz. Full stop. Best controller I ever had and certainly better than ones I have made.

Main Beach test flights (sorry, solo testing so no pics to speak of). Fed on a steady diet of B and C motors until the almost inevitable treeing occurred. It's about 15 metres up in a young (20 yo) Teak, so cutting down the tree isn't an option.

The Main Beach is just brilliant. Good, steady boost with zero roll just as low and slow as expected. On an 'A' it just sits vertically after thrust and then pops the chute. Twelve good flights on Bs and Cs and it looks brilliant in the air. A little more laundry room and it would be perfect, so proto #2 gets started tomorrow.

This will be a kit.

Pic in the tree shows one fin may have separated slightly but is still locked in the airframe. If the weather Gods deliver some focused wind over the next day or so I might even get it back.

I really want to see if that is TTW joint failure at the MMT, 'cause that's what it looks like to me.

Go-Anna! is your basic disappointment. Even after swing testing the boost on two test flights was definitely unstable. I'll add some nose weight and re-test, but this will prolly go on the back-burner while I concentrate on more important things, like finding lost parts shipments and playing with the farm.
 
Way cool. My wife makes quilts too, here are some she made for homeless kids this year:

and working on one like yours. We figure someday one of these kids may walk on Mars.
That's fantastic! My wife quilts as well, but I'll be dinged if we ever saw that NASA Panel in the last pic there...

Note: Quilters probably have excellent parachute-making capabilities.... My beloved says she's willing to give it a try...

Started building the Backslider. It looks like the CG won't be quite where Peter recommends (although it may get there after it's painted), so I need to do some math and experiment upon completion.

That is a Great quilt!!! My mom used to spend the winter quilting. I still have alot of hers and cherish them. She would have love that creative designs that went into that quilt.
That’s awesome !!!!
Quilting is pretty special sometimes a unique design becomes something you can enjoy forever👍🏻
 
Gloss coats on the LOC Star Fighter-152, 2 Cool for Spool and NewWay Big Bertha. First two are ready for decals, Bertha needs some fin masking and paint before decals. Got primer on the Estes Protostar, and sanded some primer off the uhh, urr, ummm, oh yeah, the Estes Cosmic Interceptor- it has been so long since I first primed, I forgot it's name. :angiefavorite:

Tracked my 'lost' shipment of rocket parts. Suddenly, after filing a complaint with Australia Post, my package has apparently flown from its stalled state in San Francisco, cleared Australian Customs, got shipped to Sydney and been transferred to my LPO. In 24 hours, not the usual 4-6 days!

Time travel! Magic! Bewitchment!

I hate to complain, but seriously 3 'lost' weeks means something to me and my customers.
 
Enjoyed blowing black stuff from my nose after finishing the exterior of a stick of seven 38mm nozzles. Next: Cut them off one at a time, drill, form exit and entrance cones.
 
Fortunately, graphite is pretty harmless chemically, and everything that's blown out didn't get into the lungs (which is kind of what nose hairs and mucus are for).

That said, though... wear a mask.

Are you sure you didn't need to pick? There are some times that only a pick will clean the nose. After horse riding comes to mind for me. A nose blow after 6.5 hours in the saddle is just not sufficient.
 
Raining as I write, so I'm just imagining the Main Beach proto slowly disintegrating in the Teak tree. Cest la vie, on to the next one.

Started work on Main Beach proto II. Shortened the nose cone shoulder and inserted a bulkhead which should give me the extra 10 mm or so I wanted for extra laundry space.

Set a kitting deadline for the end of July. Sounds like far away, but we have a house to sell in the meantime (not ours).
