Galathee

[periscope]

Hi All - I'm trying to research the Galathee model sub - it's about the right size for our smallish local club pond - I've downloaded the manual and I found a mention of the sub in the review section of the forum for last August. Can anyone help with any recent information on how the build went, (and how the boat performs) particularly if anyone has build the sub as supplied by the manufacturer without any home mods. very grateful for any info/pictures.

Regards,

Hello Tim how are you?

Hello Tim how are you?

I have been running the sub now for over a year and have found it to be a very nimble well balanced desighne.
However the suplied pump is not so great and the tube pinching valve is ok but a solinoid works better.
Also the 2 studs intersecting at the far edges of the forward wtc have to be sealed with the suplied washers and cut carefully if not they leak.
The drivetrain and prop are durable and robust units.The kurt knozle/rudder realy make the sub performe well and as a hole are well made.Same for the CNC tray ,well desighned and strong.Be carefull with the rod seals they work well but can get easly damaged and leak so I added bellows for more protection.

Its set up for 6 volts but I found a 12 volt slb that fit exactly in the bay! And that wy I get longer faster run times even with all the lights I put on her for the cave diving I do at the Den.

I probably have taken her down to at least 20 ft and had minor leaks.The ballast system works very well and once ballanced this sub is like an elivator with easy control,just be sure to use a better pump,the one suplied cant take hardly any dry run time and is weak.
If you use a solinoid just wire it to open when the pump turns on ,on the same circuit.I just use a micro switch atached to a micro servo.

Watercooling the motor and if necessary the ESc would give even longer run times.

I left the front cap lose so that acsses to the lights ect inside the cap can be reached for a nice efect of a lighted nose cabin..

Out of the box its a great fun build but in operation some of the above hardware needs to be updated.

And get the optional fittings kit it looks realy good.

Well thats my opinion on the Galathee sub.Let me know if you need more info.

I am inprocess of wrting the article about the Compressor Ballast system updated with diagrams and pictures that will sure to be a good read.
Also one on the Robbe U-31 with the above system ,thats going to be a goodone,to build!
Have a great day Dave

There is the PDF on

There is the PDF on the Lecma website-

There is also the Thunder Tiger Neptune. Bigger than the Galathee, but still portable.

This model has caused some disquiet in the model submarine community by virtue of it's ready to run availability. However it is also available in kit form, and from what I've seen of it, it is a well designed model- a bit of an ugly duckling in standard form, it could easily be modified by a competent modeller into something more scale looking.

Thanks Dave and Andy -

Thanks Dave and Andy - some good info there. I really do like the look and the dive design of the sub but to be honest I'm not a very experienced builder - my present sub is the Robbe Seawolf - I followed the plans carefully and I'm pretty satisfied with the boat but of course it's a dynamic diver and I need to get into static stuff. I wonder what sort of pump would be siutable to replace the existing one and how would a solenoid be used to replace the valve system? If I could figure this out I'll have a go at the sub because of it's size which is considerably smaller than some of the other models I fancy like the U47 versions made by two or three manufacturers, but 5 feet long would give me some steerage problems on our club pond

Many thanks Guys,

Ian.

A lot of people have

A lot of people have converted Robbe Seawolfs to static divers. You can use a peristaltic pump and a bag, or a piston tank, or a fixed thank and a pump etc.

Also some nice upgrades for the seawolf, including the novel use of a syringe as a ballast tank-

Hi Subculture, Many thanks for

Hi Subculture, Many thanks for the info - I'll have a look at the sites you've given me - this might be the way to go to get me used to static divers. I'll let you know when I've sussed it all out.

Thanks again Mate,

Ian
