Lets hear about your Thunder Tiger Neptune SB-1.
Try also a new set if the above look good and no change,all I did was to install the antena in a more horizontal web and circular way as originaly done see the pics.Also check each and every servo if there is one bad it will behave like this as well.Check all radio connections.
Let me know your findings and will go from there Dave
Same sub acted badly in my pool, however: servo jitters, loss of throttle control and finally complete signal loss, all at a depth of three feet!
Why? Because while it is a fresh water pool, there is enough salt in it for the chlorine generator to function and that significantly absorbs the radio signal! It does not need to be a 'salt-water' pool in the sense of being the same salinity as sea water. Even if your pool uses NO salt it can have a very high TDS (total dissolved solids) that can quench the signal, especially if it is a concrete pool. You local pool supply store can test that for you.
See if there is another body of water you can test it in (with a tether attached!)
I hope it is as simple as that for you.

I have recently my Neptune SB-1 submarine and have finally found the time and a suitable spot in the house to begin work on it to improve its features and performance.
I am looking forward to making a few modifications and changes to the basic model and I already have a few ideas down on paper which may or may not work as only time will tell and your much appreciated, and hopefully given, advice will assist me in completing these tasks.
My first question really is how do I upload pics to this site ? It asks me for a URL which I'm sure I don't have, isn't that something to do with a website or something ?
Jim
One is called BETA and the other says click here to upload images and files (I use this one).
1. click on the click on here to upload images and files,this will bring up a multilpe upload box that says browse at the right hand end.
2.click on this and then select the file/folder on your PC to upload from (i'm assuming you using windows),then select the pic you want to upload.
3.click on save and it then should come up on the file upload box.
You can upload multiply pics doing this and then when your finished click on ok,just becareful of the size of each of the pic's as the uploader may time out.
I'm having problems with the endurance of my Tx battery,it goes flat after a couple of minutes regardless of how long the Tx has been on charge.
I'll be changing the the radio out for one that is legal in Oz as the one that came with mine isn't.
cheers,
glenn.
The things you will incounter are 1 the sub does not last very long on a charge and the supplied charger is is not the right one unless they have shanged it.Another thing is that the radio although is very good has a strange problem ,it will discharge its battery very fast ,but this happened after several years of use.The radio is a futaba unit.
So what I did was to install a 10 channel JR PCM radio that way I have much better reliability and flexability ,I have added a tillting 90 degree color Sharp mini fishey camarra just installed.
The Dive plains must be changed to a larger pair so that effective diveing can be made and is an easy fix.
The aft horizontal fins are too big and act against the small dive plains , they must be trimed down like i did and made a huge difference!
Same for the larger prop and Kurt Knozel /rudder ,that realy made her turn much tighter.
So you can do these simple mods that make it much better ,but right out of the box the first 4 items should be done.
I also installed a much larger 5000 mah lead asid battery then to now the 2 ea 5700 mah units that gives tremenduse power and run time.
I also added dual prop bow thruster as sees in this forum and now dual counter rotating simitar props !Lots of fun !! I will be postting the pictures in a new topic later.
Over all this sub is fantastic and what a great reliable sub its been for me and I have taken her very deep beyond 30 feet in cristal clear water in rivers and cave springs ,hence all the mods ,I like long run times and plenty of enhancements
Check her out well on the first run should be good out of the box but later you will see what I have and improvements you might want to make,have fun!!
Can any one help me, I just bought this sub first the radio didn't work, I fixed that. Now I turn the sub on. The servos work, but the motor barely turns, and the pump wont turn on via radio. The status lights turn on, then shut's off. I tried charging with and without fuse, nothing. Then I used my digital charger for a few minutes and everything worked. But i don't know how many amps (or C) to charge at, and how many volts per cell for charging top off. You guys are the only people that could help me, Thank You.
The battery should be charged with the right range of charger of no more than an amp for that battery.
Sometimes the assemblers make mistakes especialy witha machine as complex as this one so have some patience and corect ant problems .
Also if you need to get parts there inexpensive ,like the controlboard 27.00 bucks at RC Warehouse or a bit more at Tower Hobbies,use the part #s to look up parts in the first website.
I have had very good luck with mine right out of the box she was right on and ran like a swiss watch ,but I had to modify the hell out of it to get better performance and enhancements,but in its original form she is one great sub!!
Dave
The stock charger if not changed from the one I had should not be used it just does not charge the battery enough but it might have change by now ,make sure it has fully charged with a voltmeter.
With the current lipos 2 ea. 5700 mah ,I get about 3.5 hours but i run allot in rivers with a good current and with bow thrusters and lighting exetra .But without the mods she would only give 25 to 30 minuts out of the box in a pool,so thats about what she will do..
Dave
i've also changed my factory supplied radio for a different one because i couldn't get more than a few minutes usage before the Tx battery went flat.
cheers,
Glenn
So what Idid as to extend the Lipos charging cables so they can reach to the round fuse port quick open cap,there the cables plug into the 2 chargers.
It is strange that the radio goes bad in that way in a relativly short time or even out of the box ,it must be correected as its mostlikely a component malfunction ,I will find out some day.
I just finished installing and programing the OSD Pro or On Sceen Display from Eagletree Systems ,in no fewer words it is ASUME Captains! Complete real time display of every sytem peramiter and temperstures,depth read out in MM s ,motor temp and prop RPM ,battery percent remaining ,motors wattage since it reads from the main power supply to the ESC,Pack voltage ,thraghtle position in percent,and then to top it off individual texted notifications alarms like I inputed "LOWBATTERYGOBACKKTOBASE" when the lipos reach there low state at 4.8 per cell .All these readouts are clearly seen on sceen or not at will and with a remote meneue changing function 6 more pages of info can be displayed!I want to try GPS read outs next,who knows just how deep those signals might go ,but the host of data that it brings to one is incredible!
The OSD is only about 75.00 bucks and wow what it fun it IS!!
Have fun on sea trials she is a fun sub that hovers to a milimeter no sweat!

I had to find the lower cut off point since I use now Lipos to 7 or so volts which take a hell of a long time to get that low even with all the extra stuff on my sub not to mention dual motors!
If your getting wierd behavior at failsafe check each and every servo I had one bad servo with the 10 channels and corrected it right away.
Dave
AQUASUB what did you use to enlarge your fore planes and how did you make them?.
So far the only mods I've done is fit the 6 Blade option to it and mount a gopro Hero HD camera to the front of it.
cheers,
Glenn.
cheers and enjoy.
glenn.
I've been out with the sub lately at the local creeks.
