Linear Actuator with a bunch of stroke options?

My teammates and I were looking at these actuators: https://www.firgelliauto.com/products/deluxe-rod-actuator

Has anybody used these? They've got stroke options between 3" and 30", 2.5"/sec, 100lbs (45kg)

Probably not fast enough for racing, but what about flight sims?

How does that compare to actuators like those from the BFF design?

We'd like to move to actuators on our flight sim if we can for simplicity.

BFF can move at near what is stated and at less cost, but you have to build them yourself. 400mm per second is damn fast.
@SeatTime is building his own actuators as well.
as for those actuators, a bit slow yes, and you have to work out how to power and control them.
Theres no real "simplicity" when it comes to actuators. SCN6 is probably what you would need, but they are expensive.
DC motors and a lever drive like BFF shows on his site would do it.
That and someone here has already done a Joyrider with large DC motors on it.
That would be a simpler option.

Normally anything around that price point will not be fast/strong enough for a sim. Always carefully read all specifications. Eg. Can push/pull 100 lbs not lift, and the 3 inches a second is at no load (still slow). I think that even a flight sim still needs to be reasonably quick, so that the motion keeps up to what is being seen on the displays. The BFF design is much quicker/stronger. What is driving your sim now?

Gotcha, given that I don't even know what SCN6 is, I'd guess you're correct. What are you referring to specifically with the lever drive?

Right now we're using some modded wiper motors (ground isolated by the people we bought them from). It's not up and running yet, so we'll see how that goes.

Sounds like we might be better off just upgrading to better DC motors. We're applying for $2,500 in funding from our school to make a better model, so we're trying to figure out the best thing we can do with that much money in the time we have (1-2 months?)

If you can supply a picture/drawing of what you are building, we may be able to advise more, it could save you some time/money.

@narthur157 http://www.xsimulator.net/community/threads/jugles-flightsim.6470/#post-71639 heres where they do a motor gear drive lever thingy.
I am guessing you have not gone through the BFF site much then. Theres a lot of info there.
Seriously ,set up a nice DC motor and maybe put a cover over it if you have to.
Take the time to get it right. Looks like you have had a few issues relating to the rush and time frame.

That's a really nice build..Here's what we've got at the moment:

It's still very much a hack. We just got our motors running with the jrk tonight. PSU seems to be tripping though, because we can only run it in one direction or the other. Reversing it doesn't do the trick (99% sure this motor is grounded correctly). We're definitely looking to transition away from the pulley system.

Our outer part of the frame bends in under load, which needs to get fixed.

Frame looks good, and yes, you said you need to spend more time making it stronger.
I know the issue regarding the motors from Rob, he said get "these" and you bought something else.
Not sure on PSU tripping, how much output power is it?
Otherwise, Id really suggest go along the lines of Jugles sim build. That would be a good base to work from, using the motor/lever/gear setup, is strong and powerful.
As I recall, you were planning this with a VR headset, teh general discussion is that with a VR, big motion is not needed.
@noorbeast , can you advise further on VR and actual motion?

Hi
Have you looked at the open build stuff?

I like it. Id bet tempted to order without a stepper motor though and just bash a worm gear or direct drive motor on, make my own feedback and off we go.
Kinda like what I did with the brikie actuators
Thats really well priced for a complete kit.
Have bookmarked it and will have to "find" some money to buy a pair.

Hi
They also make a wear strip that fits onto various t slot, which takes vee type bearings, so might be possible to beef it up

I sent an email asking approximate RPM of motors and approximate linear speeds

That sim looks pretty good.

As far as VectionVR goes, I actually e-mailed them and they said their code is being integrated into the Oculus SDK. So, motion cancellation should "just happen" before the consumer release of the Oculus.

"We will soon release all the necessay code on GitHub.
It's basically a modification to do in the Oculus Library.
If your application is already integrated with the Oculus Lib, it will be transparent for you once you refer to the patched version of the Oculus Lib.

There is also a client application to fetch the data from an IMU and send it to the Oculus Library.

Once the code published, we will contact everyone interested to let them know where to find the necessary information.

Best regards

Ah, yeah I totally misread that. I just read "patched version of the OVR" and assumed they meant Oculus was including the patch.
