First, welcome to the hobby of r/c submarines! Hopefully folks here can help you in getting answers to your questions. Here are some thoughts and answers from me....
I have a similar sub to the one that your friend got for you. Let me ask what may be an obvious question: was the r/c transmitter (also) turned on and using fresh batteries?
- Do you recommend that one as a starter or another one?
This depends on what your goal(s) are for r/c subs. Do you wish to stay with ready-to-run r/c subs or are you interested in assembling your own? As a starter sub and a fun pool toy the protocol sub works fine. It submerges by being driven down by the two outboard propellors, which makes it a "dynamic diver"...meaing that in order to submerge the sub needs to be moving forward. A "static diver" operates much like the real ones in that a ballast tank fills with water to submerge the boat. Most of the r/c subs seen on this site are of the static diving variety.
- How about a kit? Do you sell them on this website?
Kits are available ranging from very basic hulls where you need to add the internals all the way to those kits that include everything except the actual radio control gear (which is just the standard r/c products used for boats and planes. Just don't use the 2.4GHz stuff...it won't work with subs.) Some folks even take the larger styrene model kits of subs and turn them into fully operating subs.
Prices, as you may imagine range all over the place.
The SubCommittee does not sell product, but there are a number of great vendors that support the SubCommittee...check out the banner ads and/or check out the vendor page on our main home page http://www.subcommittee.com
- Went to my local RC Store and they dont deal in subs, not enough interest. They directed me to TowerHobbies web page and they would order anything for me. Only 2 RC Subs DUMAS USS Bluefish or DUMAS Akula?
Hobby stores are really only into ready-to-run or almost-ready-to-run product. You'll not find most of the r/c subs that you'll see mentioned by folks on this site in a hobby store. The one exception is the ready-to-run Thunder Tiger Neptune submarine...which has an operating ballast tank. Tower Hobbies sells it. (btw: the two Dumas subs are not ready-to-run, they're kits.)
Okay, that's a start. Please tell us what your interests are, especially around building skills if you're interested in building a sub.
