Hi everyone, so this build is almost finished but I figured id start documenting the rest of it on hear, when completed it will have full functional bb gun turrets that rotate, fpv cameras that track with the guns, an auto balance counter weight that compensates for the weight of all turrets training to port or starboard, functional lighting, and of course regular rc mobility, I cant figure out how to resize pics but I figured out utube and posting videos lol, so I took a quick one of the turret setup so you can see how I did it http://youtu.be/7dUPCg3HOd0 |

Got a lil more done today, hooked up the pressure bottle manifolds for the cannons, and installed my 12v smoke generator, it runs in conjunction with the motors, emitting more smoke the more throttle you give it, its just going wide open in the video because i just plugged it into the lipo directly just to show everyone. Its actually mounted to the bottom of the hull, but the output tube lines up with ducting in the deck to direct the smoke out the stack https://youtu.be/80MkCClWOf4 |

Hi. Is that Bismarck a scratch-build? Or a Trumpeter. PS. I am contacting the board administrator to help getting back my account!! Something had gone wrong after I reset my email address and password in the account setting and thereafter couldn't log in to my account.... Regards, Aop. |

Its a 1/200 trumpeter model, but I had to drastically alter the hull to accommodate the turret rotation servos and the bilge keels are bigger and made outta lead to help with stability since the turrets are quite heavy. |

Did some more work td, got the turret auto list control installed, still tweeking the gyro on it to make it a bit more efficient (its a bit slow) and my battery is a bit weak too, but you get the idea, as the ship lists form the weight of the turrets training to each side, the counter weight compensates but rolling to the opposite side, hears a video of it https://youtu.be/RqZiARShrbM |

What an ambitious project--since your firepower represents a direct threat to my fleet, I reserve the right to fire back. If I should hole your hull, it appears sinking is certain as there's no internal bulkheads or bilge pumps.  With those hull modifications you've made I want to call it Space Battleship Bismarck...

Ha ha! It for sure would sink, its ridiculously heavy :p but I was thinkig of adding a bilge pump, but its so cramped inside it would have to be small, but its mainly going to be a show pony, shooting old forgoten models and prefabricated target ships to the bottom of my family's pond, then exploring the wrecks with my rc uboat  im still working the kinks out of the auto balence, I think my gyro is kinda messed up since im only getting 2.5v to the balence motor at full list, should be 6v :s these little gyros seem hard to find also as I am not seeing any on ebay any more :s

| Post subject: | Re: 1/200 Bismarck rc conversion |
yea the gyro is defective, i just tested it, thats y the balence compensation was so slow, if i use a direct input that counter weight rockets across the deck like i planed, so i have a new on on order, just waiting for it to come it, also i needed to tweek the guns a bit cause a few wern't reloading after each shot, so i had to de-solder and lower the interuptor pin inside the gun to accept the bb more freely, i used all brass tube for the guns, including the magazine feed so that id loose minimal pressure due to expansion when firing, the only expandable tubing is the coiled tube from the solenoid to the gun its self, so they pack a good punch, and im able to run them up to 300psi without tubes popping off or expanding off their barbs, i was able to put dents in my garage door with them, and they reload as afast as i can pull the trigger the only problem i have is i can only get about 30 shots total (each turret fires 2 bbs per shot mind you) before i exhaust my C02 bottle which is only 3.5oz's, i couldnt fit anything bigger since the hull is totaly filled with components now lol

My new gyro for the auto list control arrived today in the mail, hooked it up and it works perfectly, and it has a sensitivity gain on it so i can make it really reactive to listing, i'll post a video later once i finalize the install of it, it just kinda sitting on the deck with wires comming out of it now lol, also i have it hooked to a channel on the reciever which relates to a dial switch on my tx, so if i want elevation control of the cannons, i can simply overide the gyro and cause a list to port or starboard with the counter weight, effectively raising or lowering the barrels of the guns, as they are set to a neutral elevation normaly. This build is nearly complete at this point with only a few wires left to connect, and im just waiting for the servo extention leads to show up in the mail and i can take her out for a maiden voyage  I also ordered a bildge pump with a water sensor to be placed in the lowest part of the hull, which is the drop down area under the aft turrets, ill run a little hose into the area and place the water sensor there also so any leaks or water over the deck that makes it inside will collect there and be ejected. Im super excited to take it out at this point but most lakes are frozen so maybe ill just slide it across the ice....... jk

https://youtu.be/3r6PmCTljUA well, aside from the bilge pump, shes ready for sea trials  I took a quick video of the funtional test on all her systems, including the fpv cameras, which you can see on the tv behind the ship in the vid, sorry the quality of whats on the tv looks so crappy, my tablet had a hard time capturing the image, probibly because the camera on my tablet sorta sucks, but you get the point. Normaly smoke would be comming out the stack but I turned it off because theres no fluid in it right now, I decided to decouple the smoke generator from the engines and just run it off of a small voltage controller that has a knob to control the voltage to it, so I can dial in the amount of smoke I want, I found the motor coupling method didnt make enough smoke unless I was running the motors at a high rate of speed, essentially rocketing across the lake lol, so it wasnt very realistic since the motors I have in this are way more then I really needed to propel the ship at scale speed anyhow. K enough about the internals, hears a video, ill shoot another of some gun target practice once the snow leaves enough to pull my summer car out of the garage so I dont pepper it wih bb's during the live fire exercise

So I installed a small bilge pump with a tube that leads into the sterns low point with the water sensor leads next to the pick up tube, so I wanted to test its flood abilities if the bow took on water, hoping the water would simply run to the stern and into the bilge, so I floated it in the tub and began adding water to the bow.....yea, it didnt run to the stern and just started to go down by the bow, with the stern lifting out of the water lol, so looks like ill need to add a bilge to the bow too, so I ordered some more parts, it worked good for water comming over the deck aft of center, pumping it out of the stern bilge and over the side, but any water comming threw the deck forward of center would collect in the bow and get exponentially worse, eventually sending her bow down and sinking, ....which would suck, man, im glad I tested it first

So, she does float and on the proper waterline? Request photos of a bathtub float test, assuming it fits the tub. This could be fun for... harassing people and of course sinking other model ships. |
