Did you miss the 'Start Here' Thread? If you read it you would have found this:
http://www.rcgroups.com/forums/showthread.php?t=288890

Then when you have read this inside & out and studied it, you ask the guys here some questions, you mention that you have read it and they are more inclined to believe you are genuine, and not some random kid who picked up the model at a hobby shop sale 'cos it wos cheap'.

Research first

Then Sit on this forum for at least about two or three months,

Then buy the kit,

Then when you make the kit, people will be alot more helpful. And your entry into the hobby, will be much more sucessful, and thus longer term.

Most people use one of Dave Welch's WTC kits in the Revell U-boat. Here's one link for some info - http://www.rc-submarines.com/id51.htm#welch . Dave includes a CD with pictures, instructions and diagrams with each of his WTC kits. You'll have to provide things like the motors, electronics, make your ballast "gas" tank. etc. You'll also have to provide all of the servo pushrod seals yourself.

I'm using on of the SWM WTC's in my 1/96 scale BALAO model of the HAMMERHEAD. Nice WTC, just some general directions. The SMW WTC's have nice rotary servo outputs thru a watertight seal.

I also have two D&E Miniatures WTC, one 3" (infor repair with Dave Merriman) and one 3.5". Nice units with detailed instruction manuals, equipment trays, installed motor and gas tank. The D&E WTC's have linear servo outputs thru a seal.

You'll also want to check out the SubCommittee .

thanks cgbob!

i've been researching for about a month now, i looked at a ton of kits and setups, but really couldn't afford those kits, thats when i came across the revell kit and also i had seen several posts on here where they were converted to rc.

i know it will be a heck of a challenge for my first build! but in my opinion thats what makes this hobby so cool!

ok a few more questions....

radio system...any suggestions? i've been looking at a airtronics vg6000 75mhz, it comes with micro rx and 4 standard servos...

i'm having a little trouble on ballast types...
i want to build a static diver, but real sure which system i should go with...

gas or water pump?

Dave Welsch's kit comes with (or you can purchase with) a pump style RCABS ballast system composed of a pair of inflating air bladders. This works exceedingly well in most cases and will be the system that I use in both my Revell Type VII and my Trumpeter Seawolf kits.

The Airtronics VG600 is perfectly good. I use it in my big 66" Nautilus with no problems. Cheap and reliable, its a good choice. Getting a six channel is overkill for the Type VII, as you'll only need four channels. If you've got future projects planned, however, six channels will allow expansion for neat stuff like torps, lights, sound, periscopes, etc.

Hope that helps a bit.

I suggest the Dave Welsch kit. I'm building the Type VII-C conversion right-
now and If you follow the directions and pics on the disc, it will almost put
itself together. Good Luck!

i know its an aircraft freq, but i'm only planning on running my sub in pool, so i don't think it should matter that much, plus this setup comes with micro rx, servos and micro speed controller... what do you guys think?

The motors you need to order from GWS are-GW/LPS-RXC-CS. They are about $13.00
each. They work perfectly.

Hi all, I've been reading these threads on rc subs for a while now whilst my revell type VII gathers dust. I'm going to bite bullet soon and see if dave welch can ship me one of his kits to the UK. Does anyone know if I can get these motors in the UK?

I'm surprized that I'm the first to comment on the radio choice. The problem is not with your boat in the pool, but with what you might do to someone's aircraft in the vacinity. Also it is against the law!!!! See FCC 95.207 - (R/C Rule 7) On what channels may I operate? You might also want to check FCC 95.218 - (R/C Rule 18) What are the penalties for violating these rules?

Actually he's says it's on 75 mhz not 72. That's ground.

Sorry,

I did catch that one jimhurley. Jaykymm. don't waits your money because if you ever go to an event and it's near a model airplane field and you hurt someone you could go to jail and have your equipment and model taken away from you.

There as plenty of good radios for subs like the one you order except they're on 75 mhz. Hitec has some good ones too.

Being an RC jet pilot as well as a sub driver I would highly recommend you do the right thing here.

Thanks,

Steve
