Song Class Build (212A as well...)
After nearly half a year playing around with my Dragon Shark, I started to build a real scale sub.
This is my Song Class during its initial water test.... and some video:

Nice to hear from you again cmpang. Great looking sub
 Notice something different about your Song, you didn't attach the sail planes. Last edited by redboat219; Jul 14, 2009 at 08:40 AM. |

Thanks for the good words. No cosmetics yet, just an initial water test to check out the among of ballast, balancing, power setting etc. May need another tests (three or even more) to settle on everything... Yes a really good looking sub, suitable size (especially in Hong Kong) and reasonable price... |

Hi cmpang, greetings from Singapore. My Song class kit + WTC arrived more than a month ago. Have studied the instructions and hope to commence assembly work soon. Would like to ask if you had managed to use the original bayonet joint rings (to hold both halves of the hull) supplied with the kit. For mine, the two rings do not fit and will require a lot of sanding and filing to make them work. I am trying to find a better joint design and if your Song class has one, can kindly share? Regards.

Not sure if it's just the camera angle but she looks a bit bow heavy.

yes I do use the original bayonet joint rings and indeed need a lot of sanding to make it works. Actually each side of the joint is made up of 4 pieces of CNC ABS plates. The CNC cut is excellent and it is the glueing up of the 4 pieces that offsets the centers ... Arkmodel should supply the plates intact and let us do the glueing... I have reflected this to Feng... AND it is not difficult to do. Just slip the 4 plates into the wtc transparant tube and glue them together and they are all line up correctly... simple... Nevertheless, after that much touching up, the joint works great.. |

While building the Dragon Shark I realised it is Archemedies that keeps the sub from sitting level in both surface and submerge situations. The hull is more or less symetrical from the buttom up to the conning tower. Being situated forward from the CG/CB, the additional buoyance it offered while submerged will tilt the bow up. So in order to be level while submerged, the ship has to be balanced a bit bow heavy while surfaced. Since the Dragon Shark is not a true scale model, I managed to get it right by adding a sonnar dome at the stern. The size of the dome was adjusted to balance out the buoyance of the conning tower |
