Ah, OK. So the "extra" A10-0T is in the middle, separating the booster and sustainer. Just finishing mine up. I have about 18 of the bad H21 date code motors that I'd like to use up in some entertaining way.CPMEV®
I had three A10-0T that were replaced when the first motor went Cato. I then scotch taped them together into the booster and scotch taped them to the A10-3T in the sustainer (Chad staging). Sure enough, all three booster motors Cato'd causing @BABAR to dive for cover. Good times...
Not sure. I sent email, got a response and have since received the replacements from the “recall”.I've sent multiple emails to Estes support with no response. Not sure what's going on. I guess it's time to call them.
Yeah, I got the H21 replacement quickly. It could be that between WSC and the H21 recall, they're up to their arm-pits in Martians.Not sure. I sent email, got a response and have since received the replacements from the “recall”.
Scott Hunzicker is actually here in Texas at the World Spacemodeling Championships as part of the Estes contingen right now. I suppose I can try to catch him and ask him about it some time this week.
Finished the Der Big Bandit along with Der Big Alpha. The kits are from Galactic Manufacturing, and I made the decals myself. The Alpha’s NC came from the dearly departed Big Daddy. It suffered an E12 Cato with minor damage. Still haven’t heard from Estes after a month.

Tuesday in the park, I think it was the 4th of July.
We've launched at night several times before but never on Independence Day. The fireworks are a tenth of the craziness that occurs on New Years Eve. It's way too dangerous to be out then, especially in Waipahu. Recently, the trade winds and morning rains have been persistent. Fortunately, the winds went from 12mph down to 5mph toward the end of the day. You can see at the end how loud it was getting.
We didn't lose any rockets this time. Gary's Orbit separated. We found it on our way out of the park but without the payload. He also got back the payload for the Firebolt, and I found the body within 20ft of the Green Eggs.
There was a beautiful sunset in the sky. Unfortunately, the side cam didn't capture the Birdie launch. The Twin Vikings and Xray were still gorgeous. The dual launch worked spectacularly. The payload may have landed on the gym roof after separation. The chute opened late with the Loadstar because I used a plastic chute in case it drifted away. One fin popped off and was easy to reattach.

I just got some Q-C18s myself. They look like they put out a pretty quick burst over a longer burning C6-3. Should be interesting..I've had a few crazy/scary flights of my Centuri on C6s. C5-3 has always worked better. Just checked OpenRocket, it shows 33fps launch rod speed on the C6, which probably explains a lot.
Tomorrow it's going up on a Qjet C18. That's 62fps off the rail, which hopefully sends it straight. It'll be on a field with trees some 300' away in each direction.....

Very straight flight on the C18-4. Not terribly high - 375ft, but I didn't want to risk losing it. Ejection timing was spot on.I've had a few crazy/scary flights of my Centuri on C6s.

Several classic rockets on a moderately windy summer Hawaiian day in the park
The weather was forecasted to be light winds until 9am which is what happened. I invited Gary but didn't advertise the launch since I wasn't sure what the winds would do. Overall, it was a successful day except losing two nose cones that separated and drifted out of the park. The C6-5 wasn't able to handle the cam and altimeter, but the C5-3 worked great. I didn't launch the Nike Smoke because I discovered it lacked a shock cord. Next time...
Gary bought a box of Quest B4-4FJ which are working much better now that they fixed the nozzle issue last year. I finally got my replacement motors from Aerotech. Karl has been doing a lot traveling recently, especially with the championships. I finally was contacted by Estes about my warranty replacement request for the 6/15 Catos. They apologized because there's only two of them in customer service. Apparently, my request was put on hold because I emailed them several photos in a zip file, and they're not able to open the file. It's possible the file was corrupted (but not likely). I resent the photos individually so we'll see if they're able to receive the photos now.

I'm definitely going to choose wisely what those C18s get put in...lol!Very straight flight on the C18-4. Not terribly high - 375ft, but I didn't want to risk losing it. Ejection timing was spot on.

I'm not at any level some others are at. I'm just slowy catching up on a few missed out years. No over compensating, just overwhelmed with work to do. But, one step at a time.Thanks for the videos.
Do you have any Totally Tubular long BT-20s(I think 34” from Balsa Machining ServiceHowzit Tom.
Please say hi to your lovely wife for me.
I'll be prepping some of your rockets for a launch two weekends from now, weather permitting.

A 34" tube would have shipping charges that would be prohibitive. I ordered a BT20 coupler that was 34" long from erockets a while back. They asked if they could cut the coupler in half because the shipping charge goes up dramatically if the parcel exceeds a certain length.Do you have any Totally Tubular long BT-20s(I think 34” from Balsa Machining Service

I have some me fin cans and nose cones I’d like you to try out. Shipping these parts is reasonable, but cost of shipping whole rocket is a bit much. Does BMS shipping to Hawaii run much?

No, that is Back Slide.Was that HSR?
In our experience, the retro puff technique at least doubles the reliability of achieving HSR with a side puffer, but potentially with the loss of a bit of hang time. But isn't the act of a backslider blowing off its nosecone tantamount to a retro puff? The delay time is a critical element of success, as is the CG.No, that is Back Slide.
HSR, hasn’t been introduced to the Islands yet to my knowledge, but we are working on that.
I have literally high hopes that @Dotini ‘s retropuff technique may greatly improve the consistency of Back Sliders, which in my experience are far less inherently reliable than HSR.
Who knows what the correct term really is or will eventually be? We are all still inventing it. We see that the side puffer will either swiftly gyrate into HSR or, about 10% of the time, go nose first and burrow into the turf. In retro-puff mode, the model stalls at apogee with tail down, descends ominously tail down for a spell, then gradually and naturally slides into HSR. It never lawn darts - unless you've a much too short or long time delay. So this method gains reliability and durability for your model, but sacrifices ultimate "performance" in terms of descent time and rate of descent. I mean it's not much, but if you're counting every last second in competition, you might want to chance it with a conventional side puff from just below the nose cone. We are still going to quantify the difference in drag on boost and let you know the results. There is also a minor weight difference due to the balsa plug....is “retro-puff” the correct term? I like it. I am guessing the loss of hang time is simply due to increased drag on boost?
Has this happened? I have been thinking that a "puff" wouldn't be necessary at all for HSR, BSR, or BFR (what I call "CP Shift") rocket designs.It never lawn darts - unless you've a much too short or long time delay.
