Could be. It's interesting that they still call these Igniters. Bill S said they had to stop saying igniters because they're regulated heavily. These don't seem like they're more hazardous than the starter.
Laser-X clone. The goal was to use the 20/60 balsa transition I had. It was one of those items you throw into your cart to qualify for free shipping. @neil_w was helpful in walking me through paint.net. Because of problems with applying the decals, I ended up printing the decals three times until I got it right. I’m using a Mylar streamer, so I applied thin CA to the fins before papering. I figure the toothpicks will break off but I have plenty of those.
The trade winds continue to be strong. It makes for a nice time at the beach but not in the park. I’ll probably fly some streamers soon. I have this idea of attaching a spy camera to a kite. Just gotta figure out how to keep it from spinning.

That Laser-X came out fantastic. 
I’d say it’s a descent two foot paint job.That Laser-X came out fantastic.
That’s going to leave a nasty burn mark on the carpet that’s going to be difficult to explain.
I forgot to mention that I forgo the nozzle fins on the original so I can attach a Booster-60. I was rather disgusted with it on my Sidewinder, so I put it in the bottom of my parts box and will take some time to located it. I had to estimate the relative weight. I know the Booster-55 weighs 44g.
My latest scratch build. I call it the Fletch Cargo. This is the first time using Micros Set and Sol. I'm finding the Set tends to wrinkle the black ink from my inkjet printer. It eventually dries flat, mostly. Not sure if I'm using it correctly. Also, the CA used for gluing the acrylic to the balsa transition cause the plastic to fog for about an inch. When I use a spy cam, I'll have to suspend it using a foam piece. The main body paint is a new color from Rusto called Thunder Cloud.
Here's the OR file. I purposely made it so the Stability is 1.5 with a D12-5.

Nah, plenty of aqua blue available.
Actually had a difficult time with the paint. The new can of grey initially came out like cottage cheese so placed the can in hot water for a bit but turned out nicely after sanding off the powder. The blue started cracking and had to sand that off twice.
Karl from Aerotech responded and said it appears the clay was not properly impacted into the motor. He's sending me replacement motors and should arrive around June 3rd. I really appreciate their customer service.
Sunrise launches with the Hawaii Kai Rocketeers
Christopher and I met with Gary (@kurinin) and the Terry family at Sandy Beach park. Roger (who I met through this channel) also joined us. This was our first time launching at the park. Usually I see stunt kite fliers when I drive by the park from Makapuu. The weather forecast was for under 5mph and was actually 8 to 12mph with gusts up to 17mph. This has been the typical story for the past two months. Since we were taking turns, this video is just straight handycam with no slomo which made it easy to edit.
After the launches, we had breakfast with Gary at our favorite coffee shop in Hawaii Kai. Daniel the Rocket n00b (@lcorinth) said the best part about club/group launches is meeting afterwards to talk shop (maybe with bored spouses). Heartedly agree...
Later, we went to the rifle range, so it was a bifecta day for explosives. I didn't bring a full load out like I usually do. Just plinking with my VEPR-AK and AR. I spent several hours the night before loading 5.56 rounds, but I discovered at the range that I grabbed the 300BLK instead. Anyways, it was a short trip to the range.

That was a great day, thanks for making the video for us. I just wish you would have identified the guys as to who they are on TRF.
This video helped me realize what a small launch area and LPR can do to provide fun. After seeing this, I'm going to get the rest of my Estes rockets I bought (24 rockets, built, all with no parachutes for $50.00), ready for the 3 grandkids to have fun with.

Roger has it, will see him at the next launch.
From Ron's email it appears one fin missing, one fin damaged.
I am grateful to Roger for spending the extra effort in looking for the rocket.
I scoured the beach and rocks, apparently it was in some bushes.
Now that I think about it, I should have attached my Tile to this rocket.
When it disappeared I could have activated it to chime so I could audibly hone in on it.
Next time.

Or get the license plate of the truck driving away while chiming...
I made a Thomas Viking Special. I also made an Eggtimer Apogee. I bought two and maybe messed up the first one when I inserted the connector backwards. Sorta melted it while taking it out. I’m now tackling the Classic. I’m not really too interested in them so plan to give them away to my YouTube viewers. I’m waiting for the Lipo for testing the kits which is problematic with mailing to Hawaii and the local RC stores don’t seem to have the right ones.

When I saw the video title I was thinking we were going to end up with cloned @ThirstyBarbarian s in bunk beds!
I skimmed it, was expecting to see a launch video. No dice.
when I saw your pic, I thought you were doing gap staging, which COULD be done with a purple of Vikings, but would require more finnage in the tail, less up front, and A LOT of nose weight. Other problem is the booster may be stable post staging. I can imagine your Son’s voice saying this: “Stable BEFORE staging—— good. Stable AFTER staging —— bad.” He’s just got the perfect inflection for that kind of humor.
anyway, hope it’s a good flight. I am predicting if you keep it on a streamer the body of the rocket may come down horizontal. Fingers crossed.

Is this a pun on "Clutch Cargo". I am thinking of a 60s cartoon; possibly only in Chicago land ?
Or transgender thirstys with really big.........
Never mind.
Dave made a follow up video with making a booster out of a Viking. He also made a recent video for gap staging.
Flight went awesome. It had 8g of clay to make sure it was straight.
Perfect Conditions in Hawaii Kai (despite the sunrise rain)
Met with the Hawaii Kai Rocketeers at Sandy Beach Park. The morning rain caused spontaneous rainbows, and the moon was spectacular after the Super Flower Blood Moon last week. This was the best wind conditions for the past two months with only 1mph. I have so many rockets waiting that we made plans to meet at the Waipahu Community Park on Memorial Day.
The Handycam seems to focus better in direct sunlight. With the Gopro8, it was on 4k/60fps so the slomo footage is a bit choppy and eventually filed the 32gb SD card. The day was a modest 27 points but I'm giving myself 10 bonus points for launching with the group.
I was surprised how high the scratch built Fletch Cargo went on a D12-5. I thought it was heavier than that with the altimeter and cam. Next time, I'll have to run the Astrocam to get better beach shots. Maybe I'll catch a breaching whale during the winter season.
Christopher, Gary, Roger, the RC guy Ken, and myself met up at the Island Brew Coffeehouse afterwards for much needed post launch debriefing and nourishment.

More perfect conditions on Memorial Day with the crew
Day 2 of perfect launching conditions, this time at the Waipahu Community Park. This was the crew's first time launching here. I met Gary through the rocketryforum.com and met Roger and Ron L through the YouTube videos. Roger returned the rocket back to a very appreciative Gary after it almost went into the ocean a couple weeks ago.
This was a very productive launch day. With the bonus points for launching with the crew, this was a record 49 points. The Orion Shuttle was used for testing the wind and had simple streamers. I'm not sure why it spiraled, perhaps it's getting old. The Chiller had the altitude record with an altimeter plus a booster so 6 points. The F-16 had a FS altimeter but landed in a tree so it loses a point. Afterwards, we rescued the rocket using a small rake attached to the pole. I was glad to get the Flightsketch Mini altimeter back because Russ has run out of stock for now.
The Orbital Transport and the Multi-Roc with the booster worked beautifully plus both gliders were awesome. The Patriot had the upgraded 24mm motor and can definitely use the D12-5. The scratch Gild Navigator had an unfortunate hard landing. There doesn't seem to be a reason why the chute didn't deploy, so I'm wondering if the C11-5 charge was the problem. I plan to insert a modified coupler in the tube to help straighten the tube.
The V2 worked great despite the broken shroud lines. I shoulda used an E12-6 instead of the E12-4. Two of the included paratroopers dropped to the ground, and the third drifted off into the horizon. I also gave a bonus point for Christopher catching the rocket. I was going to sell the lovingly used V2 on eBay but decided to give it away in a future video.
We didn't decide on a "launch of the day". I had the highest altitude, Gary had the best effort for catching a rocket, Ron L had the most impressive explosion, and Roger had the best experimental rocket. This was the longest video I've made. I didn't include the GoPro3 footage but was still difficult to cut any of the other content. We probably won't have a low wind day for some time so enjoy. As a veteran myself, I hope you also had an excellent Memorial Day.
Update: Ron L got his Astrocam back from the other side of the canal. Unfortunately, the cam didn't record both flights. I've had trouble with mine also. It has to be charged the night before and sometimes the blue light doesn't want to come on for quite some time.

I am not sure the USAF is gonna want the word to get out that an F16 was taken down by a spear gun!
Good composite post, as usual. How long does it take you to edit and splice these?
I'm coming late to the party, so please pardon me if this information has been posted already.
dontknow. It is much higher for the 9V. This is from the Duracell data sheets, conveniently all linked from a single search on DigiKey. (You'd think Duracell would make it as easy, but no.)
Where "the bigger the better" is true is in capacity. The figures in the table are for fresh cells. The bigger ones will remain sufficient through more launches. And yes, that matters, obviously.
There exist handy little plastic things that let one substitute (my memory is hazy) either two or three cells in parallel, either AA or AAA, and use the combination in place of a single either a C or D cell. I seem to recall they come in two sizes, so maybe one that combines AAA and once that combines AAs? Or one that makes a C and one that makes a D? Or both?
Paralleling n cells not only multiplies the capacity by n (which might get 3 AAs into the ballpark of a C) but also divides the internal resistance by n (which makes 3 AAAs better than single AAs, but 2 AAs would still be better). So those might be the best way to go; four or six of those containing whatever number of small cells could pack a big wallop for a respectable length of time.
Oddly, that's not true, or not always. The maximum instantaneous current from a cell is dictated by its open circuit voltage (i.e. its nominal voltage) and it's internal resistance. Good old Ohm's law, V0 ÷ RInternal. For common Duracell Coppertop cells, the internal resistance is nearly the same in anything from AAA through D, except AA which has much lower resistance

About 6 hours. I don't consider it a labor because it allows me to revisit the day.

Curiously, I haven't seen JFT around lately. I appreciate the data you provided. I was using 4xAA in my DIY controller but subsequently switched to 2x9v in series (18v). It has to be good quality 9v batteries (Amazon brand) because I found out that cheap 9v won't work. I also tried rechargeable AA and 9v batteries and those didn't work. I like the current set up because it's light and relatively reliable. I have been thinking about trying a 12v motorcycle battery. (The city would get upset if I drove my car on the park grass.) I also thought about Lipos but access to those is problematic in Hawaii. I have dipped my starters in the finest gun powder I have which is working well. I just got a pack of the new starters to play with.

9V batteries are good, but an expensive way to solve the problem. They don't last very many launches considering their price because of that high internal resistance, and the fact that they're made up of a half-dozen tiny little batteries.
Perhaps a better solution might be:
https://www.amazon.com/2-1x5-5mm-Connector-8x1-5V-Plastic-Battery/dp/B01C5J4M70Eight AA batteries will give you a nice 12V (with fresh batteries), much higher current than 9V batteries, more launches per load of batteries, and rechargeable AA's will likely work fine. It'll also be a lot lighter and easier to deal with than a motorcycle battery.
