update: first Deck and the guardrails 101_9237 von efferman auf Flickr

great idea and mechanics. i hope you get it finished till the deadline

nice idea and good shape. good luck

it is the hull from the 4031 fire rescue. the final weight oft the tug i can not guess, because i have problems with the optical design but if is everything going wrong i have a second hull to increase the floating abilitys edit: the testvessel has changed its place with the final katamaran layout. yes i know, harbour tugs are never katamarans, but i need the water displacement of two hulls. 101_9235 von efferman auf Flickr

i use liftarms s propellerblades. it would be interesting how good the tailrotorblades of the new helicopter are working on this voight schneider

maybe because there is lego education available. or they sell not good enough

good morning guys, the RC is implemented and i made a little testdrive in the bathtub conclusion: the bathtub is too small to learn to drive

it will have a Technic look with some panels on the hull and other technic parts above the water line.

The Harbour Tug My entry of the "to sail the technic sea" contest is a floating vessel in the style of a Harbour tugboat. The feature of my tugboat is a Voith Schneider propulsion system. A classic propulsion system for ships works with a horizontal driveshaft and a propeller. The advantage of the vertical Voith Schneider propeller is, that it could adjust the boost of the propeller in all directions, without using a rudder. The vessel can move sidewards and rotates in every radius which the captain wants. To get a little view on the maneuver abilitiys i made a short Video of my harbour tug Technical Datas Two propellers in Voith Schneider style powered by twoPF-M motors with a gear ratio of 1:1.4 Two Pf-M to adjust the pitch of the propellers. The pitch controls the direction of boost. Two receivers and transmitters One 8878 LiPo accu Dimensions width: 280mm length: 600mm height: 360mm weight: 2790grams The Deckhouse and the Bridge is built modular to get a easy access to the electric parts the two dishes are used to show the driver in which position the pitch of the propellers is. on the afterdeck i have added a nonworking winch for the tow line The stabilizer sword and two of the airtanks which are adjusting the waterline of the vessel. more pictures on flickr and Brickshelf If you want to take a look on the building process, please click here Thanks for reading -------------------------------------------------------------------------------------------------- Welcome to the work in progress thread of my "to sail the Technic sea" entry the technical base, the voith schneider propellers, is finished. only RC and the design things are to do. for people who didnt know what a voith schneider propeller is, please look here

yes, when you modify the bonnet

why you are sure that i build a winner moc? first my voith schneider must work

thanks i finish frst the truck, then comes the trailer and in between i have to sail the technic sea. when my idea works

then my english isnt good enough to understand you.

they are both pushed completely in. my theory is the following: the right one has at the inner diameter no gaps between the liftarms and so they support the flexible axle to a smooth curve. the left one doesnt have this support and bends like it wants.

i think this "iconic" sets will never come back, but hopefully iam thinking wrong

yes unfortunately i have only red ones in this length. to minimize this problem and to get smaller gaps between the liftarms i have put an additional 5x1/2 liftarm on one mudguard. Is it only me or look it more round than the other? vergleich von efferman auf Flickr

simple solutions are at the most time the best solutions by the way 101_9230 von efferman auf Flickr

much better than the A-model of the 9397 logging truck

the 8x8 looks good, but i think the cab doesnt fit to it.

There are from the 8x8 log loader more pictures available?

thanks, but i think when i made the vid of the logging truck some guys will ask me why it is not RC

at the end it works a little bit harder than normal, and with a seven long gear rack it works not so good. But with the 13 long it works good enough for me. by the way 101_9225 von efferman auf Flickr

i find the part very usefull. it solved me a big problem on my logging truck gearbox
