What did you do rocket wise today?

[dave carver]

Got to rummaging around some of my Parts/Tubing boxes and found some inspiration.

Sometimes all it takes for me is a fin cutoff and I'm off and running on a new design

 

[dave carver]

I'd like to thank you guys for the kind words. Dave,Top and morlock. I tried to keep the same angles on the trailing edge and forward edge of the two fins. And the same for the fin tips. I think this is what gives it a good look to a split fin Dave.
I call these my 20 dollar rockets. I thought I'd show you guys how I did the nose cone. The coupler tube form estes is so thin I never thought it could handle the shock from the chute deployment, So I figured that the body tubes from Balsa machine the same size as the aerotech 1.9 tubes fit inside the estes 2" coupler. Stiffened it right up. Then the coupler stock for the aerotech tube fit up into the nose cone so I can put my chute and shock cord up into the nose cone. This picture shows how it all will fit togather.

The cuts on the fin angles and the way you lined everything up is exactly what I'm talking about. It has a symmetry missing from most split fin designs, most are split just to be split regardless of how it looks. I will be doing one of my own using the parameters you have setup. It will look somewhat like what you have done but not an exact copy.

I believe you have hit on why I don't really like most split fin designs. I will work on paper until it looks right before placing razor saw to balsa

Hey EstesBasher thanks for sharing !

When I cut off the end of the shoulder for access and to open as a chamber the shoulder loses all rigidity - and I do not trust epoxing kevlar to the plastic as an anchor point.

Previously had done a 'Coker' on the nose cone by epoxing in a CR just past where the shoulder starts and then bolting a bulkhead to it..worked great in a 4 inch Mega Der Red Max clone and my LOC V2 clone - but does not downscale well into a 2 inch tube .

Will try this or glue in a small bulkhead in the top of the nosecone for a kevlar loop on my next opprotunity.
Kenny
Kenny you can do this, Just run a stuffer tube the full length of the two nose cones on the inside. like this one.

Talk about a 4FNC....

I stared at my, still in the box, Estes Saturn V. Just not sure if I am ready to tackle it.
:confused2:

They're not hard. It's just a lot of small, easy steps that combine to make a complicated whole. I built my #2001 when I was like 11 or 12. Turned out great. Just picked up a 2157 for "someday".

Is that thing stable? Looks way cool...

For some reason squat rockets do very well. Take a good look at that rocket. Without fins it's a boat-tail Spitzer bullet shape. I had one I called "Stumpy" from a cartoon that was in High Power Magazine. Stumpy performed at its best with an I357 AeroTech until the shock cord mount finally gave up from all the ejection charges. I still have the cone and I do plan to rebuild...next time I can get white PVC drainpipe.

I have no doubts that particular squattie flies well.

Today I cut 8 of the gores for a new 60" parachute for my L2 project, tonight I will pick up the rest of the material and my shroud lines from JoAnns Fabrics. I still need enough fabric to get one more white, one red and then 5 gores of some other color. And straight from the big bag of DOH!...I just realized that means an odd number of shroud lines, oh well makes life more interesting.

Finally got back to my Ultimate DS today, sanding the fins and fincan. Thought about going out and sticking some fins in, but it's 105* out there! I guess summer is finally here....
I have started a build thread here:
https://www.rocketryforum.com/showthread.php?126244-Wayco-s-Ultimate-Darkstar-build
Got some rocket porn from LOKI too, 54/1600 and 76/2400 casings, both specially priced here:
https://lokiresearch.com/page/specials
Since Sharon has started mixing her own motors, we decided to add to our pile of casings.....

Estesbasher,

Do you have any more details/photos of the construction? The looks exactly like something I'd like to build.

 

[Getmore]

Loaded the toy hauler for tomorrows launch.

 

[tim cubbedge]

Loaded the toy hauler for tomorrows launch.

Just finished doing the same!

This is when it flew on the F-30 3 grain motor.

This might give you some Ideas Sooner.

Today i wanted to work on my air brakes as i dont like using servos. They cannot handle the force and are too big so i did some searching for small linear actuators and came accross a company called firgelli automations (www.firgelliAuto.com) and it turned out their founder was one of the developers for the Seawolf missile systems the brits use for their sea to air long range military missiles. He later moved into the private sector and founded Firgelli. So they specialize in Linear Actuators and recommended the fa-rms series for me as i need about 30lbs of force which i cannot get out of a servo motor. So great day for me and thanks Firgelli for your help

Finally got around to putting the recovery gear in my 24mm MD.
I've been in a slump build wise lately because yard work and automotive woes have sucked away all of my motivation.

 

[chrisudy]

Finally getting close to finishing the last of the winter builds...
Asteroid Hunter - base grey coat on.
Saturn V - painting almost complete. Needs touch ups on the lower mask
Caliber ISP - paint curing...
Ventris- completed.

 

[djs]

flew some rockets with QCRS- put onboard videos of two of them on youtube. muddy fields, but good flying!

 

[tim cubbedge]

Flew rockets at NEFAR. Perfect weather.

Arrived at ROCstock today at 8:00 AM and paid my 20.00 non member fee and bought a ROCstock T-shirt for another 20.00 so people will know that I'm a real rocketeer. I launched my Estes Magician with both D and E engines. Everything previously launched has been engines A-D, so this was a big leap for me to launch a BIG E. Now I know I'm moving up in the rocket world. It was blazing hot and humid with lots of people and great launches. Saturn's were having bad luck today. Two had recovery issues where one lawn darted and the other separated from the nose cone.

 

[patelldp]

Painted my Hawk Mountain Proteus and MAC Performance Villain. Color is Rustoleum Safety Red sprayed with my HF HVLP gun. So much better than spray cans...

Went to a small launch at a local farm

I launched my Patrol Cruiser Excalibur on an 18mm Reload - D13-5



It landed in a dam! Damn



But I had this guy come and check on me while I was trying to figure out how to get it back



I did get it back - it's pretty soggy now Think it's flown its last flight!!

Hi new guy You look to be a rocketry madman so you will fit in nicely Photos and videos are in order, you are obviously entering into realms unknown around here and I hope we can see what you are doing. I, for one, sure am.

Awww, man, that sucks As you Aussies say, she's a beauty or, she WAS a beauty. I've launched a rocket that found a 4 foot wide irrigation ditch. Same results, soggy rocket. If you can, launch further from the dam and try to get an angle where winds can't blow a recovery over the water. That rocket was too pretty to suffer that fate

 

[JERRYR708]

The Patrol Cruiser Excalibur is one of the nicest looking rockets. Would love to display that in my office for the vintage great looks. Sorry to hear about your rocket getting water logged.

Knocked out a XB-70 RC rocket glider over the last couple of days. Own design, Frank Burke style.

Done except for some minor detail markings, pushrods, radio install and 24mm motor mount install.

Ought to be ready to fly by mid week.

Here it is next to my InterR/Ceptor.

 

[JERRYR708]

Really cool custom gliders.

 

[tab28682]

Really cool custom gliders.

Don't forget that the InteR/Ceptor is a very easy to build and fairly inexpensive kit from Frank Burke. Details in the Rocket Glider forum.

I do have some more custom projects of this sort in mind, though....

Occurred yesterday - just too tired to post

I paid forward by supporting the Kopernik Observatory 7th annual Rocketfest

They hold multiple sessions and allow people to build and fly a rocket.

I always bring part of my collection to display and assist in the build and fly portions

The kids always seem to have a great time
