I'm a first time builder as well, and I would recommend the following]http://www.subcommittee.com/forum/icon_smile.gif[/img]
I'm doing an Ohio class sub, a 2m (6ft) from scratch (Except the hull, buying that from http://hjem.get2net.dk/robse/SSBN/SSBN.htm and see if it helps you on your way deciding the correct approach for you, into this GREAT hobby.
Also, take a look at www.ThorDesign.com for kits, hulls etc. and don't forget to "shop around" a little, until that perfect kit stares you into the eyes.
Sub's technology holds a few supprices along the way through design, and fitting. Lean on other builders, and get ready to learn about positive and negative buoyancy, compressed air, static vs. dynamic dive systems, radio issues and alot of other things. You've got hours and hours of great fun ahead! Good luck.
Might I humbly suggest that you consider joining The SubCommittee? Our quarterly magazine, The Report, is full of all kinds on info on building R/C subs, details of the real thing, how-to info, etc. Also, the camaraderie of joining up with fellow sub modelers can't be beat. Nothing quite like getting together with a dozen other guys running subs and sharing ideas.

Thanks everyone for all you help I really enjoyed robse website it is wonderfull. I havent finished reading all the material there but I will. I also have one more question how far can a Remote Control System reach through water? Basicaly I wanna know how far I could take my sub underwater if I had hull that could withstand the waterpressure.
quite related to what TheFreak posted, I'm thinking of a simple subs that can move, dive and surface - using remote control system instead of radio control.
if say, the subs it self is waterproof, and using a dynamic diving system - we can have the power from the controlling unit (battery, etc) with a cable run up to the boat. It will be limited to certain range of course but for start what do you think ?
1) How far can a radio control reach into the water:
Well, it depends on the water. Salty & pools are the worst, fresh water lakes are the best. Typical radios can go about 6-8 ft. into the water with no problem, but if you build a system where your antenna is draged behind the sub in a surface-towed sonar in a long cable while the sub is submerged, that problem is solved.
As you can see in the section above, the radio will not make all it that deep, unless you build the "Towed sonar" idea. Please see this link for more info on sub radio issues: R/C Submarines
