Upholder or Marlin

R/C Submarine modelers

I've just found two kits that have my interest. If anyone has any idea's on either of these Kit's can you help. Keep in mind that I want a sub with a Ballast system and working torpedo tubes.

I am assuming here you are referring to the SubTech 'Marlin' and the OTW 'Upholder'.

Both are excellent kits, and very different. OTW's Upholder is a GRP hull, the SubTech Marlin is vacuformed thick styrene plastic. Both are suitable materials for R/C models.

It is really which model pushes your buttons. The nagging glitch here is your wish for working torpedo tubes. If this is your first model, skip the working torpedoes. Get some experience building and operating well. The Marlin kit is in 1/32 scale, and this sub class carried only one 18" torpedo tube in the bow. It would shoot a single scale 1/32 17" caliber anti-escort torpedo with a model diameter of 0.53 inches. A OTW Upholder would shoot a 1/50 scale torpedo of a 21 inch caliber weapon with a model diameter of 0.42 inches. Both are do able in those scales. I generally would think that the larger the torpedo miniature, the easier it would be to build and operate. Yet both are close in size in their relative scales.

I say skip the torpedoes, build and operate either model you end up selecting, and leave room for buoyancy foam below the waterline and for the torpedo tube to add later.

The OTW Upholder takes my breath away, and so does the Marlin. Marlin was a training submarine. The Upholder could be also modeled currently as a Canadian Victoria class.

Steve is right.
Torpedos are very tempting.But get a sub in the water.Once you have on working,you will not be as frustrated.On your next kit,you will have something to go out and remind you of why you are doing so much detail and work.
Belive me,I have made a ton of mistakes on my Alfa.All correctable,and learning much as I go.
At the subron,where I saw my first group of running boats,I saw how much fun it can be.The work is worth it.
Now,my next russian boats will have some extras......

It is fun to watch torpedoes being launched from a model submarine. However, I don't believe any current RC sub manufacturers sell a kit with a torpedo option - for several reasons - one being tort liability, as noted by Manufacturer Matt Thor on this board a few days ago. With our litigious society these days, I can't say that I blame them for not wanting to be hauled into court by some Grey Poupon-sucking lawyer over a child's lost eyesight.

Subs are one of the most complex rc models that you can build. As the other guys have said - build one first sans torpedoes and learn how to make a good and reliable working sub. Then, if you still want torpedoes - take your shot.

Thanks to all of you for the replies! I'm not looking to start with torpedo's. I just want the option to be there. I've been told to steer away from vacum formed kits, pluss I'm a Canadian so the Upholder, or Victoria class is really calling to me. I just have to save up or my new wife will not be pleased. If anyone has more input please don't hesitate to contact me.

You've been handed a bum steer. Properly built, there is nothing wrong with a good quality vac form kit like the Albacore and Marlin.
