Very cool! That would be a blast to develop.

 

[U812]

That would be an expensive one in the end. Two stage. Lots of parts but maybe one day.

Thanks for the very cool link and idea!

Thanks, Layne - and I still want to see your A9/A10! And thanks, Steve - you being both a submarine and rockets guy, maybe you'd be interested in this, if you haven't seen it aleady:

Now, I wonder what we Brits would have come up with to counter raids by the V24...

wow, that is an awesome looking rocket!

 

[U812]

Funny you posted that because I'm going to have a BT-60 based V-2 soon. it's about the right scale to my 1/32 VIIC. Hmmmm..........

Actually the V-2 would be a bit small for the sub. She's a 7 footer. But it will still look cool on the deck.

A BT-60 V-2 would be about 1/39 or 1/40 scale. BT-60 is a nice tube on which to base a V-2 model because it's about 1.6" diameter and the real V-2 was about 1.6m diameter, so you get metric plans for whatever variant you want to build and where the plans say "metres", you read "inches".

For best effect, scratch-build a pod, stand it behind the U-boat, and put your V-2 in that. Launching a V-2 from the back of a U-boat would not have done the U-boat much good, so the idea was to tow the V-2 in a pod and launch it from that.

If you want rockets on the deck of a U-boat, the first thing you need is a type IX boat. Then you get to build the U-511, which really did launch rockets from underwater. Mind you, they weren't V-2s, they were basic artillery rockets. Good luck making a stable flying model of the rocket, though.

Adrian thanks for the good stuff and the link. My kind of subject matter.

Still waiting for my supplies to show up. They should be here tomorrow I hope.

But I did get nosecones and boat tails all ready to go. Decals. CD's are done. Canopies tomorrow and I'll start packing boxes Monday to ship out.

[U812]

Got my supply orders today. Boxes On Monday. Tuesday and Wed. out they go!

You really ought to consider giving classes for some of this stuff. I just reviewed your website and I would love to learn how to do this. Where are you located? Just fantanstic work!

Alumilite (the manufacturer of the casting resin he used) has how to articles and videos for their silicone molds and casting resins on their website.

Just looked up this website, very nice. What would you recommend for a starter set. I would like to be able to do some nose and tail cones.

 

[U812]

SJ those kits are fine and thanks for the kind words!

Steve

 

[RandyT0001]

SJ, I just went down to my local Hobby Lobby (couple miles away) and bought the Mini Casting Kit for about $20 (IIRC). I haven't used it myself yet (still have to turn/buy the nose cone). The 4 oz of silicone mold rubber might be able to cast (about) one 1" diameter by 2.5" long nose cone based upon looking at the container itself. There might be enough casting resin to reproduce several hollow nose cones like U812 did for his nose cones (the sloshing around method). If you wanted to cast a solid nose cone there's enough resin for maybe a couple of nose cones.
YMMV

 

[U812]

Do yourself a favor and go here:

https://burmanindustries.com/estore/home.php

You can get a better deal on silicone there. I recommend GI 1000 as it's super stable and easy to use but any of them will do.

They have Alumilte too and will ship to your door. They are owned by old friends of mine and supply the makeup effects industry with most materials. So they have silicones, all kinds of casting resins and releases you'll need. Even glove and tool stones. Take a gander it will save you some money over the LHS mark up.

Next. To get the cones real even and smooth on the inside make sure the silicone mold is placed back into the card board tube. Then mix your resin and pour a small amount inside.

In your hand star turning it and rolling it back an forth coating evenly the inside of the mold. Keep doing this spinning it in your hand as fast as possible. The centrifugal force it what you want.You'll see it start to thicken. Up end it at once and let it drain off the excess and then spin some more. Up end again. If it's real thick stop there and let it drain and stop. This all takes about 60 or more seconds or so depending on the ambient temperature.

It will take practice and a bit of waste. But after a time you'll be able to make them just perfect, light and thin with minimal waste.

[U812]

Was able to cut tubes. Cut engine tubes and pre-assemble the engine mounts. That's right you heard it right your mounts are nearly ready to install into the boat tail out of the box.

Since the mount is custom to fit the Alumilite cone it just made sense. All you have to do is a little sanding to get them to hit snug.

I'm getting real close to getting the first batch done. All the hard stuff is done.

More tomorrow.

Steve

 

[U812]

All boxed up and ready to go out tomorrow.

Thanks for the wait guys.

Steve

P.S. The canopies came out great.

 

[Rocketcrab]

Am I too late? PM sent.

 

[U812]

No crab there are still kits. It's number one of a line I'm doing. The V-2 is number 2. and number 3 was just picked. More on that later.

Go here to order: https://www.sneillfx.com/page28

Thanks,

Steve

 

[U812]

All kits have been shipped today.

Thanks for all the support. If anything isn't right, or you don't get something, or I forgot to include something just tell me and I'll fix it or tell you how it's done. Although I've made plenty of kits in the past, this is my first Rocket kit ever.

That looks nice, but what do you do with it? I mean, do you take it to the local park pond and use an R/C rig to hunt toy sailboats?

Done, thanks!

 

[U812]

Power,

It's all RC for dives. I have several subs. We go to big pools, lakes anywhere we can find to sink dummies having fun with their sissy sail boats! LOL!!!

Real working sub. RC. Ballast tanks. Yada, yada. And you thought there was such a thing.

Crab thanks a bunch!

Steve

 

[U812]

Got this today. Dummy here screwed up a bit.

Got mine today!!!! Everything looks great. I have not popped in the instructions yet, but everything looks all there. Thanks again Steve. I can't wait for your future offerings.

P.S. Here is some friendly critique'.... I threw away the canopy on accident because it was lost in the shredded packing material. Panicked that the canopy was lost, I dug through the trash till i found it. Maybe bagging all small pieces in the future would be a good idea. Just a suggestion. Much success Steve to your new company.

EEK! OK. Good suggestion! And thanks for the kind words!

Glad it all got there OK and congrats on the finding of the canopy!

If this happens to anyone tell me and I'll send you another.

Also that little piece of styrene tube was left out. I fit it in there after they were taped shut. Look for it don't through it away. That's what gets glued to the inside of the nosecone for the eye to attach to. You just fill the hole with epoxy and push it in. then glue the tube to the inside of the nosecone with epoxy and micro balloons.

It was over looked and at the last minute realized so I slipped them in through the crack. Meant to say this yesterday.

Test flew the V-23 at Saturday’s launch. I put a lot of nose weight in to make it stable – about a third of the cone with modeling clay – that put the CG just forward of the back edge of the wing and about where it should be given the location of the launch lugs per the instructions. Launched it on a C6-3, almost calm wind and was straight up to about a 100 ft., but when the power curve on the motor decreased she tilted forward and did 2 gentile loop the loops, tail slid and was rolling over to about 50 ft where it ejected with no damage. The flight delighted the crowd but not the pros. All the seasoned competitors from CRASH and COSROCS think anyone building this type of rocket is a bit crazy. They say the large wings are too far forward and very – very difficult to get to fly straight and vertical. Over all I was pleased and I want to try a single use D composite. Everyone liked the nose and tail cone – I just test flew it with a light coat of white primer and no canopy. The general consensus from the pros was to stabilize it by inducing a slight spin by adding a tab to the outer edge of the wing – that’s kinda complicated and didn’t those National Socialists use that method in ’42 for their air to air missiles? A skill level 2.5 to build and a skill level 5 to fly. It was more entertaining and less dangerous than the Cosmos Mariner flights I have seen. More nose weight and more power! – that will solve any problem! – at least that’s what I have heard. Maybe a good paint job will do the trick.

 

[U812]

Thanks very much for the most informative flight report. I'm sure it will take some more test flights before you find the sweet spot. But you got her back in one piece and that's a good thing.

I am most pleased.

The other thing would be to cut the ailerons and make them a bit adjustable to tweak in that slight roll on axis.

Next time try to get some video so I can study the flight. That goes for all of you building this unusual rocket.

Thanks again!
Steve

Just flew the V-23 over lunch time during the calm before the storm. Loaded the nose cone with more clay to bring the CG to mid wing, put in a C6-3, took it out to the vacant field by the office and let her fly. With everything the little C6-3 had she flew straight up and arced over real nice and stable like. It looked just like the old Estes Maxi Brute V2 on a D, low, slow, underpowered and with a nice ballistic trajectory after the initial thrust. I don't think it made 100 feet but continued in a nice arc and did its little glide routine for the last second of the coast. The heavy nose cone turned down then pop! ... The ejection charge went off and she drifted down towards my office. Oh No, not on the roof! Bang! The heavily laden nose cone hit the concrete cap above the bricks and the rest of the rocket fell horizontally behind the parapet, surely hitting the steel flashing or 1 inch gravel on the roof. The chute dangled over the edge as I climbed up to witness the carnage. Yes, as always, the rocked found the hardest spot to land. It was a hand molded nose cone packed full of clay, balsa fins glued on with tight bond II and plastic zap on the boat tail. With 2 coats of sanding sealer could they with stand such an impact? The only thing I had to fear climbing up the ladder was fear itself. The very end tip on the nose cone was gone but the clay and ribbing was still in tact – no cracks going up the cone. One fin had a small ding on the outer control vane. Nothing that 5 minutes and a little squadron putty won’t fix. Next up is a paint job and one of those Aerotech D’s. I will try for the same flight profile only 3 to four times as large on the club’s range.

 

[U812]

Bravo Zulu! Well done. Now I know this model can take a beating too. Thanks so much for the excellent flight report.

It has bee suggested by others that a larger chute may be in order. I plan to go to and 18 inch chute on the next round of kits.

Next time please get video. We have one so far it would be nice to see more to help me evaluate the flight performance.

Here are the pictures after the second and stable flight. #4 is CG. The others show damage to nosecone and fin after landing on concrete and 1" gravel. #1 shows the noseweight used.

 

[U812]

Thanks this gives everyone a good idea of the basic CG to start with.
