Marius, I would offer that you do not separate the topics anyways......If it applies to your LA Class sub, keep them together.

Love seeing you work on this!

My BELOVED colleges I know is too soon for these stage of my project but I hope there wheel the time when I'm gonna need some Decals for my sub.
So there is some questions rising :

1) every type of subs has a different Decals ?
2) is necessary to buy a particular decals , for example My Los Angeles , or there are some general witch can be used , and by choosing what to put on them is what determine the particularity of a specific one?.
3) and of course where can be bought at decent price all of these ?.

Can You show me some pictures about what/where/how did You put Your Decals on Subs?, or guide to another place where I can find these answers .

THANK YOU

Good Evening ,

- I advanced a little bit with component arrangement in WTC ....
- I mounted on a speed controller and receiver a piece of Velcro , and on PVC bracket also.....
- I put thicker wires to the motor ....
- I don't know what connectors to use for coupling the motor with speed controller and for connecting the battery to the speed controller ....
- I have not forgotten either the fuse that protects the receiver or the main switch ,
- I am most interested about what capacity should have receiver battery power ..... now I have 4,8 V = 4x1, 2V/2100mA - NiMh Accumulators ...
- is enough to power the receiver? .....
- if yeah, that autonomy would be? ...

I have some questions :
- what methods are most commonly used to isolate the power supply wires from the battery when they enter in the WTC ? ;
- can I put Sealed Lead Acid battery terminals in the in water if it does not fit into the WTC ? ;
- not is discharged or is short circuit?

Pictures next days . To day batery is empty

Salut Marius!
I belive it will be enough for your sub, but please take good care with that brass geared pump, i have used one in the past and the inside seals are not very good, water can easily reach to the motor under pressure. I would recommend using a Kavan geared pump. The Kavan is able to produce 4 to 5 bar without problems.

Regards,
George

SALUT GEORGE ,
Thank You for telling me these .
I wheel take care about the pump . I am not decided eat if is going to stay in the same wtc with the rest of the components or in a separate wtc along with Rubber Balloon but separated by a Sealed Wall - with on O-ring .

Unfortunately I spent all my Founds and I don't have money for another Pump .
