ThunderTiger Neptune SB-1 New Kit!


I just had to give some input on this great undersea vessel.

First I ordered it about a week ago from the main distributor here in the US in Aliso Vallejo ,CA.

Cost a very resonable $449.00 including shipping,and this sub is no light pool toy ,its weighs in at 29.3 lbs package and all and very well packed by the way in solid foam Ill be keeping that.

Well after I opened and removed the sub and checked out the quick refrence guid it was ready for a maiden voyage shakedown cruise,HA HA ! :lol: :lol: Man I tell you this sub must have ben tested to the max at the factory,just like driving that bran new Volvo off the showroom floor she took to the water like a fish ,smoth power not even a sound of a huming motor at full.

I then moved the left stick left and the sub started to slowly dive as if on rails level and steady ,perfectly predictable and scale like.

The pool I ran in is only 20 X 12 oval and 5ft deep but that was no problem ,this sub turns an incredible 2ft radius or under and fast responsive results make it a even beter for those tight canyons at the Den.

The dive was controlable almost to the inch depending on dive plane input and water pumped in,it uses a blader and roller pump along with over pressure sensor so that the bag wont be overfilled.

The forward dive planes are in my opinion a bit small and dont respond to inputs as well as the rudder since the rudder is behind the kort knozzle.

For the size of this sub it could use larger dive planes in the rear and especialy up front since it is not intended to go very fast but to manuever well is its fortay.

the brass prop could also be larger with a kurt knozzle and the bomb like aft fins must be reduced a bit and that would help in the diving as well.

This sub is a real pleasure to run though right out of the box!
As you can see the desighne is uncomnly robust and engineered very well even the shaft servo passthrughs are as good as what is seen on the most expensive diving gear for camaras and ROVs ,stainless 100% hardwear and O ring sealed every where, no sparing or omitions here she is ratted to go deep 10 meters!!,I wonder what the crush depth is !! Well I dont realy want to know. :roll:

The electronicks are impressive ,there is a triple failsafe interlocking system on board that is par none. 8)

If to deep and signal lost she will serface.

If power is too low the same result.

If water is detected inside also,the pump is comanded to reverse flow and up she comes.

Also 3 LEDs indicate the variose states she is in including normal.

The motors for both the main drive and pump are unusualy large can motors and are powerfull units,Ill compare them with my high speed ones that are also can motors.

The finish and fit of all the components on this sub and believe me there are alot are first rate ,stainless steel and high impact plastic,alen screws and philister head as well,machined stainless cross members for the planes and stainless motor mount flange with O ring seals including the main 4 mm prop shaft that has a special lip seal and greas along with a dog bone U jouint that is smooth as glass.

The main switch and vedeo on switch is located underneath the bow by 2 stainless and O ring packs threaded and caped in an inginuese setup and is adjustable.

I plan on moving the aft control rods to be in the tailcone with bellow seals,I just dont like the exposed shafts.

The inner casing is large and has plenty of space for more goodies and thick cristal clear not even a distortion view of the inner workings is great.

Body parts are easy to disasemble especialy the nose it comes off with just some pressure ,clips hold in place over the main view plate that is a thick 5mm Lexan I believe.
This plate must be removed with the tool provided and by the way the kit has some nice tools also,but any metric socket will work to get to the fuse or to charge the sub which also has its charger as well including the 6 ch serface comander radio.
Nice radio to it looks like a Futaba and full size servos 2 each and 6 ch mini reciever ,the ESC is very slow start in both directions and gives full power in both directions.

For 160 something bucks more an onboard color camara that has a funy name is available also.
,tethered of course.

I plan on changing the color to silver and red,increasing the prop size and pitch and of course installing my favorite ,the Aquadrive 2.0 for longer run time.
Triming down the bomb tail fins ,adding led lights to the front and belly and installing a color tethered camara on the outside of the front plate inside of the dome and painting the dome so that only the camara has a view and the top dome painted to look like a viewing bridge.Also a quick release opening port for chargeing and to gain rapid acsess to the fuse.
And a digital volt meter.
I dont think it needs a leveler she is sOO stable and a ADC wount hurt iether.
A filter will also be used on the pump.

For a biginers introduction to the RC Subs world of fun and to see the beuty under the waves this sub by far and I mean by far takes the cake and I take my hat off with praise to the Thunder Tiger Corporation to have developed this wonderfull fun extreamly well made and pree built kit that for 449.00$ (or less,I have some info on even a better price ) you could not find anything even that comes close to it!
Only a well funded Corperation could develop a product like this at a level of engeneering and finished product.

I highly recomend The Neptune SB-1
Well enjoy the pics and if there are any questions just let me know.

Dave Amur Ship Yard :shock:

In this picture the stern planes are modified by computer imaging to what I would like them to be.It will aid in the diving responce and make her less bomb like.

In the first production of the SB-1 there was some problems with the electronics but that has been delt with from what I can see,mine runs perfect without a single adjustment only to reverse the dive planes.
No glitches even in a pool with a moderate amount of clorine.
Also I will make the radio have a standard thraughtle its spring loaded now and will need to have some friction as well with center detent for stop motor.
I like it for the technology and general desighne employed and ease of use.I build much more complex subs and to scale but to have such a neat yet strange looking sub is just a blast! :P :P
Definatly must instal the camara though not the stock one.A higher resolution sensor with built in IR for dark underwater use,mounted out side the caseing in the bow cone on a custom mount.And vedeo goggles.
I will be also adding a vedeo overlay system for telemetry will post that very cool item shortly.

This is one fine machine. 8)

In other words you realy get your moneys worth! Its refreshing and about time. :roll:

Just modified the radios thraughtle so that it has a center detent and friction.
Mod part canibalized from a parts radio. The copper strip sping,then a fine tryangle file made the detent noch at the exact nuetral point then screwd the strip in place where there would be one on an air radio ,the screw hole and holder are all there,very easy mod,also the battery plug should be tucked inside the case prior to closing the door ,a bit tight but when done this way it wont hurt the cover door.

Works great!

I dont know yet the total run time ,radio and sub but will let you know.

Also the kit comes with a large set of emblems stickers that are of high quality,great for when I change the color to silver and red.

Also a illustrated parts manual and a very convienient carring handle that is assembled prior to use and clips off and on during launch and made from turned stainless shaft and set screws.A nice touch.

This is totally unlike you Dave, this sub is way to simple, and you cant use your technology on it really.

I wish I had a bizillion dollars of machines and manpower like TT

Its good to see one of the mainstream hobby manufacturers like ThunderTiger get involved in subs. I first saw it in Oct '07 at the Shanghai Toy Expo & was impressed with it. Not sure if they make this in-house or sub out to one of their Chinese makers.

I wouldn't be surprised to see a few other well-known brands coming out with subs based on the popularity with their RTR lines. Perhaps this is just a start.

Oh yes it perfect!

It can go quite deep,has plenty of space inside the caseing,has great efective failsafes and plenty of external room to make her more real world like.

Lights camara or camaras ,manipulators and mini hydraulics.

A great platform for the allien tecknology developer to explore more fasinating gizmos.

And if I should break something its no bigy ,all parts are available right down to the last O ring.

This machine is truly ausome,by far out performs the other makers of ready to run subs out there in every way and it comes with a good radio ,a ton of acesories standard and assembled and tested to the max,what else could one ask for?

Get one and experiance the tecknology behind this great product! Alot of fun for a great price!

And soon because they sell out very fast at this price,though I can get them holl sale.

Yes it is very refreshing and about time that a major quality manufacturer with the nuts to take on a project of this level of tecknology and make it work so well right out of the box!

I would like to see another maker top this one.

My hat is off and even a bow for a job well done.

Nice job Aquadeep. I just bought the same sub a couple of weeks ago. Sounds like the same place you got yours"Thundertiger4u." They had the best price on it. If you look now I think they jacked the price up to $499.99. Let us know about any mods you do. I'm working on a few myself. I haven't had time or a pool to test it yet but it looks very promising. It seems well worth the money.

There sold out!Wow that was fast!

Thank you DC Electric I will make postings

I have info on where to get them much less.

After running the sub every day for a week now in my pool it seems that the charger does not fully charge the subs battery to the fullest,it shuts down prematuly.

I used a digital cell charger and I got about 10 to 15 minutes more run time.

Also not a single noticable glitch or malfunction.
