    S'ok. Will have to do some tests once I get the motors.

    Stall current is usually in the range of 3x->5x the rated current.

    Now that I have the motors, it's time to unveil the short-term goal of the project. Basically, my son wants to be able to watch a roller coaster video (real or virtual) and control the joyrider using a joystick at the same time (sort of a human doing a SimTools' job). However, he wants to find a way to record those movements so that if he wants someone to ride it, he just syncs the video with the recorded motion. since Arduino Uno controller and Monster Moto drivers are in my price range, which drivers do you suggest might better fit this purpose? What device, if any, can record this motion? I know it's possible, since the LEGO Mindstorms programmable brick does this. Should I move this to another thread? Thanks again, guys.

    This is your thread so posting questions related to your project are fine.

    There is a SimTools 1.3 Joystick plugin and it can even record motion, but unfortunately there is no way to play that back. SimTools 2.0 will introduce new tools to record and play back synchronized motion, it is currently in closed beta testing. One of the suggestions being investigated regarding recording is to use a mobile phone in built sensors as a way to capture motion.

    Sweet! That makes sense since smartphones have accelerometers. Now onto figuring out which drivers to use for the Arduino Uno.

    I mean what Monster Moto to buy. There seem to be quite a few kinds

    Shannon, I read that the 25:1 ratio is faster, though 50:1 (which I now have) is stronger. Is 50:1 (70-80 rpm) fast enough for a joyrider roller coaster sim? If it winds up too slow, do I have to purchase the 25:1 motors, or can I just replace the gear box. If the latter, where can I find these gear boxes sold separately?

    You can purchase the gearboxes separately here in Australia so I don't think that will be a problem elsewhere, but what yo have should be just fine. If you really need to you can increase the CTC length for more linear speed, at the cost of torque.

    Awesome! Will try it out first. Looks like I can scrape a little more money together and purchase the JRKs after all. Looking forward to getting this together!

    Sorry, bud--what is CTC?

    CTC = Center To Center, the distance between construction objects, most commonly used when discussing the distance between the center of the motor shaft and holes in the levers used on a motion simulator.

    When someone drops an acronym like that you will likely find it in the Glossary of Acronyms and Names: http://www.xsimulator.net/community/faq/glossary-of-acronyms-and-names.66/

    Got it. Thanks for your patience and thanks for the link. Though I've spent hours researching this stuff, I still have a tremendous amount to learn. Since I am going to try to use pulleys, I guess I'll have to use larger ones on the motors. Will just have to test and see.

    It's been awhile, guys, but I was finally able to connect with my buddy in order to test the motors you recommended. They both work, but response time is very slow--too slow for a rollercoaster sim methinks. However, my friend used one controller he had lying around for both motors and it was a $12 cheap one. Am I going to see a huge increase in response time with 2 JRKs? Are the JRKs and motors adequate for this simulator? I definitely trust y'all, but after seeing how slow they were going from forward to reverse, I got a twinge of buyer's remorse. Wdyt?

    Are you talking about the 50:1 motors you linked to on ebay @SpaceKaseJase? If so then something is up as 75-80RPM should be fine. What do you call "very slow".

    Yup--those are the ones. I mean the time it takes to slow down, stop and reverse. I don't expect racing sim reaction times, but a couple seconds to go from one direction to another seems way too slow. Again, it could just be the cheap driver. Will JRKs fix that?

    I don't know what is being used as a controller but it sucks if it takes seconds, yes JRKs will provide very fast accurate reversals.
