    Hello. :)

    I'm thinking of making a three-axis motion flight simulator.

    pitch, roll, heave...

    also I'm a very beginner. so, Arduino board is a good thing or Pololu board?

    Can I instead of making iron to the wooden frame? and wooden frames can be withstand all load of weights?

    because, I asked Korea iron frame manufacturer and he told me about $1200 to only iron manufacture frames.

    I hope that max load to 100~150kg and What is the most noise free motor?

    If I try to do my best simply making what I needs?
    give me any advises, please. :sos Thank you!

    Hi @hunijjang Welcome at XSimulator.net. Please have a look here: http://www.xsimulator.net/community/search/587199/?q=3dof&o=date&c[node]=31

    After the first three pages you should know much more. A 3DOF is rather difficult to build, please collect the information provided first and later (after reading again ;) ) request any dedicated help, which we are willing to give you :)

    BTW 1200$ for a steel frame? 150 KG weight only the frame? Strong but "noise free" motors?

    Hello, Pit.

    Thanks for your advised. :)

    about $1200 is only iron frame and I needs to max load weight is about 100-150kg(What I means that 3 x 27' monitors and joystick and rudder padals, thottle lever, seat then me :grin)

    Pitch and roll is easy, heave is not so easy. Heave can be done either by having enough power to lift the whole rig, which starts to get expensive, by using a custom made spring to assist DC motors lift the rig, which is still expensive, or you could follow @SeatTime's innovation and use a heave plate built into the seat: http://www.xsimulator.net/community/threads/seattimes-dc-motor-sim.5024/page-7#post-56322

    Arduinos are cheaper but more flexible. JRKs are easier for new people but more expensive.

    Steel and aluminium are the most common building materials but @scalhoun did a test simulator in wood: http://www.xsimulator.net/community/threads/80-20-questions.6114/#post-67604

    DC motors are pretty powerful and quite: http://www.xsimulator.net/community/faq/dc-motors-shopping-list.32/

    @noorbeast your postings are as usual very kindly and informative :)
    But let me demonstrate some general points:
    1) To lift a weight of 150KG three 200W motors should be able to elevate the frame. But never expect any hard turns. If so, the needed power should be much higher. Remember the needed torque is very current intensive...
    2) Arduino/MM and JRKs are current limited. Using 12v you will need bridges with more than 50A continous and 100A peak.
    3) The listed 200W motors using planetary gears are rather quiet, but if you really need strong motors, you aren't able to avoid using winches (which are very noisy ;) )
    4) Springs can help, but if something changes on the rig (f.ex. your wife or child is driving...), the spring set-up should be adjusted.

    Hello, noorbeast.

    Thanks for your advised. :grin

    I have just now ordered 3 x Pololu Jrk 12v12 USB Motor Controller with Feedback and Etc.

    also, Tomorrow I'm going to order for plywood frame production.

    Could you recommend to me, which choices 200w any motor? http://www.motiondynamics.com.au/worm-drive-motor-12v-24v-200w-180-rpm-20nm-torque.html or http://www.ebay.co.uk/itm/12V-DC-Ge...al_Components_Supplies_ET&hash=item58b2cd2323 what is better motors for 3dof(max 100~150kg)?

    I go to sleep now. :)

    here is 11:30 at PM now. see you later and Thanks again. :thumbs

    Hello, Pit.

    Thanks for the advised, again. ;)

    As shown in the above, I have ordered 3 x Pololu Jrk 12v12 USB Motor Controller with Feedback and Etc. and Tomorrow I'm going to order for plywood frame production.

    also, If plywood is produced, I'll start making the frame. :)

    I'll hope that upload a picture to share the production situation ... :grin

    so, I needs all help a lot.

    see you later and Thanks again. you too.

    Before you go too far ordering things @hunijjang it would be a good idea to work through a design. Even if it is just a sketch to start with post a picture of your design idea here and members can give you feedback on what is likely to work and what will not work.

    Hello, noorbeast.

    Yes, that was too far ordering. :rolleyes:

    then, It is starting, I'm being a worried. ;)

    I did attached file with 2 pictures as you shown, I was drawing it such as powerpoint then saved png files. :D and I know that my pictures was terrible. :(

    Thank you advised me. :)

    Hello, noorbeast.

    Thanks for the advised.

    Today I am talk to the iron manufacturer that about $1000 when he was making frame.

    so, Its Considering very seriously me...

    When I take by produced in the company.
    Maybe even better to me, buy from motion simulator manufacturer in USA Company or Australia? :think

    anyway, I know that is very expensive.

    as you know, I have ordered 3 x Pololu Jrk 12v12 USB Motor Controller with Feedback and Etc in yesterday.

    maybe, I probably reckoned without thinking a lot. :(

    @hunijjang let me propose something: go to a wrecking yard or anything else, collect all material what you can get (steel, wood, boxes etc.) and what you could use, bring it at home and than begin to develop your rig in your head by assembling all these useful parts (only in your head yet.) That is my way: I examine till such time I got the solution how to use something which seems to be useless at the first moment. P. ex. : in my rig you can find a mounting of a street sign...
    Cost: nothing. Fun: big. Experience: great. If it fails: one more experience ;)

    Hello, Pit.

    Yes. you are right. Though we may fail, it is worth challenging. :)

    If I failed, then try it and again, when it strive for success. :thumbs

    Hello all :)

    Its arrived last week Saturday. (3 x Pololu Jrk 12v12 USB Motor Controller with Feedback and Etc)

    so, I try to make the necessary testing to 1/10 scale, Within a week.

    and I have updated the attachment file but also that is lousy. ;)

    I think about Production of aluminum plate material.

    AL6061 and T5 or T10.
    What materials did the most good? :sos

    I guess most people use welded steel tube, but I went with aluminium for my build, most of which bolts together. Some use aluminium profile which also bolts together, but it is expensive.

    some people buy a cheap $100 welding set for building their frame and have taught themselves to weld via Youtube.

    Hello, noorbeast.

    Thanks for the advised. :)

    It is maybe, producted of wood frame. http://www.xsimulator.net/community/threads/2dof-motion-base-for-playseat.5976/ and looks great.

    and Do you know where can I buy this http://www.xsimulator.net/community/attachments/img_4267-jpg.16748/ on the right side linkage.

    also the Moter mounts looks great!

    I planning to order this motor x 3 http://www.ebay.co.uk/itm/12V-DC-Ge...al_Components_Supplies_ET&hash=item58b2cd2323

    Right hand 2, Left Hand 1 and that is fine to the fit in the my frame design? ;)

    Thanks again.

    Hello, noorbeast.

    Yes that is corrrect. :)

    also rods and I just still thinking of the frame thickness.

    and I found this when I searching potentiometer motion simulator and then as shown it.

    https://www.google.co.kr/search?q=potentiometer motion simulator&newwindow=1&biw=1280&bih=888&source=lnms&tbm=isch&sa=X&ei=3vfZVIyzDJDm8AWO4YGgCg&ved=0CAYQ_AUoAQ#imgdii=_&imgrc=54V5TzEc-4BVVM%3A;8AOjGuq8SDjwnM;http%3A%2F%2Fjohngw.nfshost.com%2FImages%2FX-Air_Sim_5.jpg;http%3A%2F%2Fjohngw.nfshost.com%2Fxair.html;800;600

    http://johngw.nfshost.com/xair.html What I want his make it done.

    because, The my target point is not the jet engines aircraft.

    so, What I mean I just flying to the light sport aircraft with x-plane 10.

    someday, I'll be a challenge for light sport aircraft certification. ;)

    Thanks a lot. :D

    Hello, noorbeast.

    Thanks and I saw it the last time you told me about it. anyway, his rig is 95% done. looks great.

    also What I mean, I just neeeds to this(Ball Rod Ends and Hardened Rod and Block Rod Supporter)
