Hello to all fellow Captains.
I have been experimenting and building several systems into my Typhoon an Engel Masterseries and what a hull!
Well what I have found out that by combining regular seringes modified to work as hydraulic rams ,working with the Tecknics Lego robotics components that are very cheap,very well made and can be CA d together or screwed together and will never rust and needs no lubrication and best of all runs great in water since they are made from high impact plastic.
They also make neumatic rams and valves but I prefer hydraulics for the folowwing reasons.
1 If air leaks from the system it will cause the sub to go out of trim.
2 Air is compressable and causses the components to jerk at activation.
3 Hydraulics do not have the above side effects and if there is a leak it just goes into the free flood areas.All parts are outside of the pressure hull except the pump and micro switches.If I had a video of the operation you would be impressed with how smoth and realisticly the masts and doors oprate.
Also there are no 3 way valves just the rotary valve I mentioned in the new products post.It is the selector valve by which I operate to select which system beit doors or mast or what ever I chose to operate,then I turn on the pump ,a windchield washer gear pump,in the apropreate direction and up or open or close they go individualy,verry cool.
If you are interested in seeing more about the components e mail me at firstname.lastname@example.org
or vsit the bricklink.com then tecknickis parts under parts catalog.
The apllications are endless with these parts and if they break or wear out no big deal there all available for pennies!
This is realy interesting and could change the way it used to be done!
Imagine a RC sub with no mechanical bulkhead passthrughs,or bellows or seals that wearout or fail at the wrong time.
Well with this system only tubes will come out and activate the rams that move the dive planes or ruuder ect.(especialy a must for those hard to reach or in accessable ares just like the real subs there are no bellows,before I used a watertight servo ,it works great also but can fail )and not to mention the masts doors and I forgot motor pods that retract! Ya and operate thats also a feature on the Typhoon and is on mine see pics.
I treid to get the best shots but my camara is not so great.
Enjoy I still have not dicieded to name myself in relation to Technicks Legos
Dave PS The Scale Ships Oscar II is in route,cant wait to see her !!
