Here you have a couple of short shots from my last patrol. Notice the remarkable way ahead the submarine keeps after stopping the engine in the first one.

And it turns pretty good for a modern Soviet boat. My 1/72 ALFA has about a 15-foot radius submerged. Even worse on the surface.Here you have a couple of short shots from my last patrol. Notice the remarkable way ahead the submarine keeps after stopping the engine in the first one.

You using a gas type ballast system?
How about some close up shots of the innards of that thing?

It uses an Engel piston tank, Dave.
The module is almost identical to Ramesh's, only he used a bigger tank, which caused a few issues at first. Looks like they're all sorted now.

Slick!
Thanks, Andy.

Juan,
Watching your videos makes me really glad that I bought the Akula. Looks fantastic on the Water. I am still incredibly jealous and of the pond.
At least I now know what to do with the pink foam stand that gets sent with the kit!

Yes, it's an ENGEL piston system and the WTC is a copy of Ramesh's one (thank you again for your unvaluable thread about its building). The system was refurbished last winter due to a failure in the BTS, and tested a bladder system with a water pump. Went good, but you had to be very careful not to overfill the bladder. When piston system worked again, reinstalled it an rebalanced the submarine. Dived control improved.
As you can see, surfaced waterline is a little bit higher than optimal one, but have to say she performs good enough surfaced. Trimming and balancing took it's time but its worth to do so, cause then you´ll have good perform also dived, as HHSNBN always recommend. Also thank you for that lesson. Have to say that witout the information and experiences learned in this forum, this results wouldn,t have been possible, so, to you all, pals.Comment

Nice neat installation. Thanks. Hey, we learn from each other. Lot's of good hands giving good, experience-based advice. No BS.

Was it the relays that failed? This seems to be the most common point of failure, and is cheap and easy to fix. I prefer transistorized power switching, which is much more dependable. Engel don't do transistor boards. A chap in Germany makes some nice boards which are proportional via magnetic encoder, but about 75 euro, so not cheap. Another alternative is Pololu who do a feedback controller, this one is very high tech in that it offers full PID tuning, but some might find setting it up a bit daunting.Comment

No; have no idea about what failed. I checked and cheked, but no way. Then sent the tank and the BTS to ENGEL; they deeply checked and, surprisingly, told me everything was OK. So I mounted again and now is nicely working. Electronic mysteries.Comment

There are no mysteries in electronics, they work, they don't work or they intermittently work/don't work.
I personally like to find something wrong if something fails, especially on something pretty hardcore like a model sub, because sods law says the next time that unit fails, it'll happen when you're down at the bottom of the lake.Last edited by Subculture; 06-27-2014, 03:58 PM.Comment

Good to see your boat is still going strong. I found all the little appendages a little fragile, so mine is mainly on display these days but I just gave the WTC a whirl in the bath and it all still works fine, so she can go into active service at short notice.Comment

Good to hear that. Yes some of the appendages are very fragile and you have to be very careful about them. What about a wolf pack patrol? BTW, I'm looking for Isaac Peral's submarine plans. Quite difficult to get, but if I can find'em, will try to build a 1,35 LOA operational replica. Stay tunned.Comment

Hello Juan Carlos,
I to am interested in Isaac Pearl's work after seeing the 2 replica's in Barcelona. Have you contacted the Barcelona Maitime Museum on plans?
I wish that I had known of you when I was in Madrid several years back. It took me 3 days to get my visit to the Madrid Maritime Museum completed. First day, I found out that they colse at 3:30, second day they had a Columbus Day function and closed at 1:00 (Museum is located in the Naval Headquarters Building). Nothing is translated into English!!!! Finally we found a guide who spole limited English. The saving grace was an American student in Madrid who was there showing his parents around!
Both Museums, Madrid and Barcelona are 1st Class and should not be missed!
Regards,
MyronComment

Hope there's another chance. Yeap; regret to recognize that our foreing languages level is quite low. Regarding to Peral's submarine, I tried with Naval Museum at Madrid; they said they have no plans about. BArcelona's Museum is "maritime", so they don't have plans either. I'm trying now with Cartagena's naval architects school, as they have done a replica. I've started my holidays today, and are near Cartagena, so I'll insist on it also at Cartagena's Naval Museum. Will tell you about the results.Comment

Have you tried getting in touch with Pedro Gomez? He seems to be very knowledgeable on early Spanish submarines and may be able to assist.Comment
