Building tutorial of DragonShark II submarine(Piston tank)

[Guest]

Hi everyboay,I’m Andy.Many of friends who build submarine model in first time,they always ask me need a detail building thread.So I collect some photos and videos when I build this boat,post this thread to help these peoples.
Ok,before we build it,let’s open the box and see what inside?Dragon Shark II is the second generation of this production.It used piston tank instead of waterpump tank.Piston tank has more speedy and high reliability. This kit has many modification such as longer hull and suitable for new electronic devices.
I have taken away foam blocks from the box,if you buy from shop or internet ,foam blocks will fill in box to protect kit parts.
This kit is made by inject ABS,it's strong enough but very smooth.The middle hull is a transparent tube you can see inside it anytime.




















This is the core device,piston tank made by Al-metal.Arkmodel’s new device BCU(ballast control unit),it can supply multi fuctions to drive and protect the piston tank and boat.



Servo tray
Servoes are excluded in kit,you must buy seperatly,I strong recommend buy waterproof servo,of course you can buy any 40g standard servo but you must seal it by silicon seal glue.

I use silicon seal glue motorcarbin and read endcap,motor,coupler and shaft must connect together.O ring round motor and insert to motorcabing to fix propusion system.









Inner bayonet must glue to forecap,handle,and socket must sealed in endcap.






Now I can assemble Screw rods,cnc parts,pistion tank together,that's a basic WTC.

4 X-rudder can fixed in the tail and connect with ruder arms,PAT they must in 90 degree .








Switch,lights antenna must be sealed and fixed in conning tower.




Sticking conning tower and deck together by AB glue or silicon seal glue .


Adjust shaft and rear hull position to keep motor runs correctly.Sticking rear hull and rear endcap together.




Piston tank should connect by PVC tube to rear endcap.so water can inlet and outlet.



All cables from conning tower will connect cables out from fore endcap.Deck should be stuck in middle hull by AB glue or silicon seal glue.



Assembling is almost finished,seems not bad,next step is adjustment,it’s not a easy work.
