What did you do rocket wise today?

Canadian Space Agency? (Alright, yes, I'm a smartass.)

I'm on their waiting list!!!

Thanks Guys but I am partial to the Black Brant II

Contact them first, they may say it's drop ship form manufacturer (I was trying to find the LOC Cruiser back when planning for L2

I believe it's in stock. I was trying to bargain them down a few months ago cuz it was in their inventory for a long time. No dice.

Opened a box of Ebay goodness...



I've never seen the Electron Beam as a 'kit' before. Was this common?

 

[NateB]

I worked on the motor mount for my 3" Punisher and drew up plans for my next project, a 38mm prototype for a unique scratch build.

I dug up an old box of hobby supplies this evening and rediscovered some forgotten items...

Jetex Power

And I found an unused fuel gain inside!

Rich, I'm mentoring a College Rocket team and we will be using a 12" 4" OD. 3.75 ID acrylic payload bay. I don't think there's enough plastic in the shoulder to get it down to 3.75".

3D print an adapter...

 

[BruceS]

It's unstable, because whatever makes the actual model stable (base drag I presume) is not accounted for in OR. Try moving the stage CG override to -800 inches (yes you read that right).

Wow, what a difference that made! Apogee 328'
Now the hard part, actually building the damn thing. ;-)

This is my 4" Splatnik. Solid Styrofoam, 1/8" dowels for antennas. C6-5 motor. At it's last launch, a guy with a 6' tall midpower asked if I had thought of doing an upscale version. Today I started it. It will be 12" diameter with a 3 motor cluster, D or E.

Love the Sputnik look. How do you plan to accurately locate and drill the holes for the motor mount and "antenna"
I'd love to copy it but I can't wrap my mind around how to do the drilling.

 

[Vdutel]

Today I started a multi rocket stand.. Got the idea from this sight googled a few sites and off I went to make it.. One more trip to the hardware store to get the rest of the parts...

Almost complete on my

[SeanW78]

Yesterday my son launched his team's latest TARC build. Good up, a little heavy, so a little low, but a tangled, homemade chute caused it to come down around 43 fps and snapped one wing completely off. An adjacent wing got cracked but stayed in tack. The wing surgery included TBIII held in place with a fin jig and rubber band and then paper and West epoxy to further stiffen the repair. He hoped to launch again today, this time with a commercial chute his mentor gave the team.

Not 100% sure yet, but will post a build thread. Still gathering components.

 

[HiLonesome52]

Anyone know where to buy a Black Brant II besides Madcow(their out of stock) Either a 2.56, 3 or 4"

Aerospace Specialty Products sell them https://www.asp-rocketry.com/ecomme...Estes-.cfm?item_id=1349&parent=120&navPanel=1

Also Belleville Hobby sells them https://bellevillehobby.com/product/black-brant-ii/

 

[HiLonesome52]

Sorry about the previous post. I see now where you are looking for a little more rocket than the ones I posted above.

27th February 2020. SARA was invited to demonstrate model rocketry for the MEGA Night event at Booth Fickett K-8 Math/Science Magnet School. Watch this video clip from one of the demo rockets.

Hi everyone. Not sure if I can paste images here, but will try.

The kids and I got some bulk parts yesterday and assembled these BT-55's with 18mm motor mounts. The longest process was making plywood centering rings for them.



Cut the outer ring, bolted together and lightly belt sanded until the fit perfectly into the BT55 body tube. Removed clamping bolt and cut the centers for BT20 18mm motor tube.



Due to the small size, they weight very little. When that was done, we took a couple hours in the afternoon to assemble motor mounts, and install them.

Ended up making the following BT55 assemblies from my small parts order:
- 42"
- 60"
- 29" - 2 stage
- 24"
- (and a couple Messengers)
To be flown on A3-C6's.

Anything over 60" would have been hard to launch on a C motor, so kept it reasonable.

Couple hours and they were all done. Kids had a great time with it. Was a cost friendly way of building more rocket models. Custom fins and parachutes next.

Had time this weekend to work on the NC for my 4" Pike and fill the bad spots of the intake ducts (from the puzzle like assembly) of my QCC Explorer. Also prepped the back end of my Eagle Claw Sport for attachment of the tailcone, aft fins and Qwik-Lok retainer.

What sort of altitude are you expecting for your 60" version on a C6?

 

[RocketTree]

Hi! a rough estimate, im thinking...
60" - 300' on C6-5
24" - 800' on C6-5
The if the boosted 24" flies correctly, maybe 1200'
+/- depending on the fin design I guess.

 

[Nytrunner]

I would recommend a C6-3 for that big one. Those 2 extra seconds can mean the difference between recovery and rocket-accordion on the ground.

Agreed! Thanks for the input.
My bulk motor pack just had the 5, so will have to get a few on next order.

Decided yesterday would be a good day for my first rocket launch in nearly 40 years on a frozen lake. Launched my Mosquito, Astron Elliptic II and Goblin. Managed to find the little guy even tho nobody seen him fall on a 1/4A3, so I thought why not go for a 1/2A3. We never saw it after ejection again. Amazingly I went out about 500ft from the pad and looked around, nothing. I looked down n saw a circle mark with 3 little fin marks. It had lawn darted straight into the soft snow! Super lucky to find that, I had assumed it would lay on the surface and be easier to find. So, my mosquito will see a 3rd flight. I imagine many of them don't. The two stage Elliptic flight went well, but the goblin not so much. Goblin flight was perfect on a B6-4 and the streamers deployed perfectly, but I'm not so sure this kit shouldn't have a parachute. It had acres of soft snow to land on, but it chose an ice road.

I have a nice video where u can hear it smack the ice, but it's too big to show here.


So, no chance to give the goblin a C or D motor. Day over with 4 flights.

#jealous. I Love the Magnum Payloader. It's my all-time favorite Estes kit.

I can check Mach/Mile off my Rocketry Bucket List!!!

Launched a Blackhawk 38 on a Loki I430 to 7535 ft, maxing out at 1184 fps (Mach 1.05) and pulling 24.5 G's.

Big thanks to the Lake Winnipesaukee High Power Rocketry club. It's great to have a venue for high performance flights in New England.
