Seriously looking at this. Any opinions? Anyone actually driven one? Understand how the steering works?

The Quantum Outback wheelchair is different from the Pride Outback scooter https://www.pridemobility.com.au/outback

My Quantum Q6 edge sucked off road, always tripping the breaker and getting high centered. Useless in any grass. Terrible suspension. Permobil M3 was surprisingly lots better, but suspension still hurt on bumps. Good on grass as long as it isn't too wet or too steep. Permobil F3 was even better with less caster drag, and improved when I moved CG forward and added oil damped adjustable shocks. But I really want to eliminate caster drag completely and avoid sinking and rutting wet grass. I want to be able to get to my garage and back which is either down a short steep grassy hill from the house, or a long way around on a public road. Want to cross a log bridge to the pond edge for fishing. Haven't been there in a couple years now despite being in my back yard.

Its a car, no tank steer. No casters. So will be much better outdoors. No turn in place completely impractical indoors. Its not a whhelchair. A sort of copy of the magic 4x4 version.

Things that would put me off?
The usual no access to a OEM lecvel programmer. So it would always piss me off. Because wont steer properly. Partly because its steer system design if its like the 4x4 magic stuff, partly because it may be servo controlled? Relying on some fancy programming that you cannot fix. Had a go in a myra servo steered chair years back. No thanks... And the flop side to side magic one is worse! That goes where it wants depending on what the front wheels hit.

But if you can live with all that it will be way batter than any tank steer thing or powerchair outdoors off road.

The newer magic 4x4 is servo controlled. I wonder if it's any better. Mine isn't and wheels just flop around. And yes, you should get a magic. Atleast it uses R-Net.

Servo controlled like the meyra are also horrid to drive at least meyras implementation is. And its not just the settings, although those are not conventional, and a strange mono version of the R-Net power module and programmer is used. With some very perculiar settings... I would avoid that too. Because even if there was a programmer that we could get hold of the module will be very abnormal. And probably steer like the meyra.

I would be inclined to still look at the floppy steering magic chair. At least we can program that properly. Its only its oddball geometry that lets it down. And the fact that it also attempts to tank steer the rear wheels which cant do that. So it wastes power, makes heat. That pushes up the load compensation as you turn, and makes the steered wheel turn in extreme lock fashion. Hence the full left/right thing.

These 4x4 things all fail on the steering one way or another because the mobility controller was designed for tank steer originally. And trying to use them to steer some wheels is alien to the algorythm they use.
