Got a new wind checker from the Estes July 4th sale. This one will definitely fit the JLCR. It says it will go 875ft. It’s light so probably try the C11-5 until I’m confident to put the JLCR in.

Got a new wind checker from the Estes July 4th sale.
We got a "Dragonite" for the same purposes. Best way to check the winds.
Fun Rocket to fly. Mine is a bit heavier as I put a cardboard motor tube in the fin can and added an ejection baffle.
For the record. I've never seen more than 600ft on a D12-7 but it flies great. Looking forward to seeing this one in your next video.
Put a drop of CA on all of the plastic parts of the Dragonite. It has a tendency to spontaneously disassemble itself on lift off if built stock
What is the purpose of the cardboard motor tube?
I put a motor tube it the plastic fin units to protect the plastic from the heat and ejection of the motor. Over multiple uses the plastic becomes brittle and eventually fails. Before I stared doing this I had a Tazer that melted the upper portion of the fin can on a C6-7.
Also had an Riptide lose the motor. The upper part of the fin can that keeps the motor from shooting through the top of the rocket had become brittle and failed. The rocket left the pad and just before it cleared the rod, the motor exited out the top of the body tube and spun around in the air before the ejection went off.
Below are a couple of pics from A Helicat that I'm restoring. If you look closely you can see the stock mount has melted from use.
DISCLAIMER: I don't know the history of this rocket so I have no clue how many times it has flown but I have seen similar issues on my own rockets.

Here is the plastic center coupler from the same rocket and a perfect reason why you don't attach your recovery gear to these things.

Here is my solution. Basically grind away just enough plastic to fit a BT20 or 50 tube inside. Use centering rings to keep the tube in place.
Finally use a centering ring on top of the fin can to keep the ejection in the body tube and seal off the fin unit.

Also note that this was a used rocket that was assembled with plastic cement. A little wiggling and the rocket literally came apart in my hand.
Plastic cement doesn't bond to paper or Estes plastics.
On the D20 that spat the igniter but didn't light: I had a C18-4W not go (even less so than on your Antar) on the 4th of July. On the second attempt the motor split its case down the entire length and the model never left the pad. I will be interested to hear Karl's response to your question. He said he was going to replace the split one I had and the other five C18-4Ws I have from the same lot. I have no idea how fast Aerotech ships warranty replacements though....
Awesome flight of Patriot with D12-5, Flightsketch, and JL Chute Release
Somewhat windy and misty morning in the park with Gary (@kuririn). My wife and son joined us for a bit, then she took him to work. I decided to use my iPhone8 for the main video because it has a smaller lens than the Handycam and less likely to get rain drops on it. However, the focusing was disappointing and the color askewed.
We started at 6:30 and the softball players didn't start showing up until 7:30. A guy was preparing the field and before the Patriot launch, he marked an X in the middle of our launching area for the homerun derby. Before the Vortico, another guy walked up to us to nicely ask us to kindly remove ourselves from their outfield. We were pretty much done by then with the winds starting to pick up.
The Drone Killer (to test the wind) landed in the (mauka) tree so we started angling more to the SE (kona). We looked for it later but couldn't find it. Since it had a streamer, it might fall out. If so, some kid will be inspired. The Show Stopper was one of the Estes July 4th kit sales. I used the trifold with the elastic but will probably install a baffle since the rocket worked so well this time. The altitude on the Estes altimeter was probably higher than the reading since I don't have vent holes yet.
I decided to try the C11-7 which worked great so tried it again in the Bull Pup XL. However, the Bull Pup XL probably only went about 250ft, so there wasn't enough descent velocity to fully open the chute after the JLCR opened at 100ft. No damage. Not sure what woulda happened if I had set it to release at 200ft.
Brave attempt by Gary to launch a two motor cluster. One motor didn't ignite and the one that did probably torched the broken fin. With the wind, I'm not sure if the 2x B6-4 would return on parachute so maybe it decided it didn't want to go yet. The Dragonite worked fine on the A8-3 but one of the snapon fins popped off at ejection (and was recovered).
Gary has been trying to launch his paper X-24 for several months. This time, it went up but also caught on fire and burned off two of the fins. Appropriate in a way because it kinda looked like the M2-F2 that crashes in the intro to the Six Million Dollar Man. We'll see if Garry can rebuild it better, stronger, faster.
The Patriot was a perfect flight with the D12-5, JLCR, and FS altimeter. It makes me want to try again with the E12-6. I previously added some clay to the nose cone. Might have to add more for the E motor but seemed like a straight flight with the D motor.
This was Gary's first flight with the Flightsketch Comp. It's so small, it fits in the Micro Maxx rocket. Thanks to Bernard (@BEC), Gary might become obsessed with meeting the 150ft challenge. I don't know why my iPhone didn't record the launch. The Micro Stealth was also interesting. Ironically, I've read that the F-117 has the radar signature the size of a golf ball which is about the same size as the Micro Stealth.

Nicely edited, as usual. I anticipated problems with the BullPup on C11-7 (seems like a long delay), probably good thing you had the chute release, I think had chute deployed fully at ejection during initial ballistic post apogee course you may have gotten a zipper.
Another backup for you,No worries, backup is ready to go.

Hmmmm.........
Looks like the exhaust burned the trailing areas of the shroud. Why it did this on this flight and not on previous flights is a mystery. Used a Quest BP motor instead of an Estes this time. You think that could be it?

before I had heard of Krushnic, I tried sticking a body tube and nose cone in the forward end of a pop bottle with the bottom cut off. When motor lit, it literally sucked in and then melted the sides of the “bell” shaped tail.

Not a productive day at the park
It was one of those days in the field. The winds were under 5mph on the ground but over 10mph about 100ft up. By 8am, the winds picked up to 20mph. Although the winds are lite in the morning, starting at 6:30am is difficult because the sun doesn't fully reach the field until 7:30 making it difficult to see the rocket in the shade. My son starts work at 7:45.
The main problem was the starters that I recently dipped in stinky nail polish and fine smokeless powder. They actually worked worse than the undipped starters. The DIY controller worked fine at home afterwards. I'm not sure what the problem was with the Estes controller. The batteries are fine but was having connectivity issues. I took the controller apart and now seems to be working fine. Again, it was just one of those days.
I was surprised how far the Hi-flier went on the streamer. The wind on the ground was coming from the SE and was heading from the NE up above. I could see the rocket with its streamer hanging from the tree. After I picked up my son from work, we couldn't find the rocket. He finally found it in the garbage and the local kid brought us the nose cone. The heavy afternoon winds musta blown it out of the tree. It's a $5 rocket but good to get it down. I tried looking for the Drone Killer from last week and couldn't find it.

I was very disappointed it didn't work. I swapped out the 1st stage motor just in case. Unfortunately, all of my electrons were dirty so I replaced them with clean electrons. (That's my go to excuse when electronics don't work.)Any day flying rockets beats working.
I am looking forward to a successful Trifecta launch, it looks like an interesting rocket!
I guess at a big launch you have people going through all sorts of stages….I've heard of Fliskit launches where they launch a dozen or more of these at once. Must be interesting trying to find everyone's stages afterwards...
Is that a Sirius S.S. Centris?Drag race at the next launch?

My stages would be the nekkid ones.
Only three stager mini I've flown was the mini Comanche.
Yup (Cestris). Hasn't maidened yet.Is that a Sirius S.S. Centris?
