I don't see it as a big deal. Yes, I owned(a long time ago) one of those horrible eyesores in my backyard. The actuator(jackscrew) was a cheap unit with a very long stroke(necessary to the application) and was rated at 150 lbs, and did NOt run off a battery! It doesn't matter what your background is, it's just that most people on this forum know the difference between a 1,200 lb Bear Linear, and a Sat TV antenna jackswcrew. I'm not defending the Bear Linear, I'm just pointing out the vast differences in design parameters and application-requirements. For all I know, a Bear Linear is pure junk. But, it's easy to figure out the negative arm ratio, the total loaded weight of the bucket(plus a little extra), and come up with a force requirement. It's obvious you'll need a compact design, and also one with acceptable speed/price/availability.
Instead of trying to straighten me out, why don't you spend your time, come up with an acceptable actuator, and let us know about it. That's what I did, and I stand by my comments.
If what I said is interpreted as an attack on Chief, it's clear to me we couldn't have much fun sitting around the campfire.
BTW I've flown lots of airplanes, including jets(it's what I do). I've NEVER seen a linear actuator similar to the Bear Lineaer in any of them. So, what does that have to do with it? I don't know.
