We just do not want any damage to the system. Your input would be appreciated thanks

The gantry was to work by building a framework, with rails constructed from 1x1 blocks. The gantry X/Y axis arms are to traverse the rails with wheels. There would then be some pistons for the z axis, a rotor, and finally a landing gear for grabbing. All pretty straightforward stuff. On something like this, you do not want suspension on the wheels:
on flat ground due to the hub always being nearer the ground than the top of the wheel, all three “loops” have to flex and return for each revolution of the wheel, meaning it would be like going up a gentle hill all the time (work wise)? (unlike conventional suspension that will flex due to riders weight and stop regardless of revolutions.
MacPherson-strut suspension can be used at both front and rear. The wheel hub is fixed rigidly to an upright, telescopic, tubular strut which has its top end anchored to the frame or to a reinforced wing.
Was thinking about this, had fiddled around with the suspension setting a bit last night. I could make that work, but My worry is how... "spontaneously explosive" this game's engine is with suspension systems, was hoping to remove that factor entirely. There's also the clipping of the suspension models and alignment issues.

Among the very few prominent recumbent groups around the world precious few can boast of the long history of racing and designing bents as can the British Human Power Club. We’ll chat with club officers Alan Goodman, Barney Harle and Chris Hamilton about their full racing seasons (including the World HPV Championships), member’s unusual HPV builds and the early group history with founding member Dave Larrington. Also Dave Ashenbrener returns with an update on his “Lost Recumbent” AR-3 tilting trike which he has now produced and is available to purchase. Honza, Doug and Nina are back with their segments as well. Midwest Trike Demo Sale – February 27! Posted on February 26, 2021 by Larry Varney
A leading arm , used only at the front, is the opposite of a trailing arm, with the wheel in front of the pivot.

The big limitation that I can see, is that if there is any deflection when the rider gets on the bike, that means that the rider is essentially pedaling uphill all the time (Because he has to compress the springs as he moves forward). The other problem is that unless the springs are precisely calibrated to the riders weight this will really destroy the rolling efficiency of the bicycle. Malcolm Jacks May 23, 2020 03:09 AM

Simply put, the suspension system connects the vehicle to its wheels. In doing so, it takes responsibility for two main functions: Providing a comfortable ride for the driver and passengers by smoothing out the bumps and other imperfections in the road. Keeping the wheels on the ground as much as possible to provide traction.

Reinventing the wheel: The Loopwheels use large springs instead of spokes to give the bike wheels built in suspension
The spring system between the hub and the rim of the wheel cushions the user from bumps and potholes in the road. The springs absorb road noise, reducing vibration through the frame and into the rider’s arms and body. High-pressure or puncture-resistant tyres can be used.
Richard Quest, the designer of LoopWheel, asks “Why can’t the suspension work in all directions?” in regards to conventional wheels. Hence, the idea of LoopWheel originates. A 20-inch Loopwheel with Shimano Alfine 11-speed hub weighs 2.13kg. A LoopWheel is about 300g heavier than a conventional spoke wheel of the same size. However, you do get the added suspension and a smoother ride.

It's unclear at this point whether you'd lose any forward motion energy due to torque flex, but that can be tuned out of the system if required in any case. It's also unclear how much a pair of wheelchair-sized ASWs would cost at this point. We assume they're not cheap compared to a regular rim and tire setup. Here's some annoyingly infomercial-style video comparing regular wheelchair wheels to an ASW setup over curbs and grassy, uneven terrain.
$800 on Amazon for C load 285's - so I was a little off. I was also assuming prices of shopping around, or else the SPC's would've been stated a bit higher. 03-15-2020, 11:32 PM #6 I think that is reasonable presuming the shop is decent. Also, don't forgot to add another 100 bucks for alignment when all said and done. Be certain the alignment tech is well versed on SPC UCAs. Ask the shop for a referral if you don't already have someone in mind. shrub1 View Public Profile Find More Posts by shrub1 03-17-2020, 12:25 AM #7 03-17-2020, 01:45 AM #8 2018 Super White SR5 Premium aka Ben Affleck: Bilstein 5100s (w/ 2" Toytech Superflex), 285/65/18 duratracs (E), 18x9 Volk TE37 // 2003 Black Limited (2UZFE) aka Blacky Chan: stock the_fornicator View Public Profile Find More Posts by the_fornicator 03-17-2020, 09:24 AM #9 That's $2890 without install.

Since you're not doing it yourself and the kit includes UCAs, this is not crazy expensive. Don't know a bunch about Bilsteins but you could probably find a better deal on them or use the money for something a little better quality.

Loving this well made Schwinn! Have many miles of very hard riding on it now and it is holding up well. Zero issues and still functioning perfectly. There is a slight amount of seepage at the front forks but that is normal. I have just about worn out the tires but that is after a lot of miles, most of which were ridden on rough rocky roads with zero flats. Overall this bike is a winner. Well worth the current price.

Barel sees bikers embracing the SoftWheel. “Our wheel will enable bikers to ride faster and more smoothly,” he said. “In standard wheels, about 30 percent of propulsion energy is reserved for suspension, even if that suspension isn’t necessary at a specific time. With our system, suspension can be turned on and off as needed, reserving more energy for speed.”

Designed by Jelly Products, it’s an erstwhile standard 20-inch bicycle wheel with a twist: it comes with a suspension system built into the wheel itself. Switch them in place of your bike’s standard wheels and enjoy the most stable ride you can imagine. Or, better yet, use them for your folding bike (which, usually, skips the suspension forks to save on weight and bulk) to give it a full-fledged suspension without adding much in terms of size.
