quantum stretto anyone else got one?

Postby Jayde1976 » 03 Sep 2020, 08:55

I had one on demo for a few days and it seems pretty ok to me pretty smooth over big bumps and kerbs,goes 6.2mph got the guy delivering it to go through programming as wasnt happy with it at first but it did do what i wanted, got 16miles out of it which is ok, and goes up that steep hill in norwich town with no slowing down.. plus its narrow compared to a Q6

Great chair for what it is but the q logic cloud based programming means you'll not be able to do any self programming. If you want narrow mid wheel drive then have a look at the dietz sango m. R net in there which means you can at least buy the required programming tools.

You mean the steep hill near the market place? My chair climbs that easily even with 8 mph motors which has less torque.

A quick look at the specs here... https://www.quantumrehab.com/pdf/brochu ... tretto.pdf It looks as though it only comes with 2-pole motors which won't last long if you do a lot of hill climbing. The order form doesn't show any other motor option availible and can only take NF22 55Ah batteries. These are the drawbacks of a narrow chair.

programming isnt a problem really as i got a friendly local place which will do whatever i want.. was sure it had 4 ple motors on the demo one.. my old quantum 610 was ok with its 2 pole motors and i went miles in that without burning anything out and i carry a fair bit of shopping on that old chair.. I mean the hill from price of wales road up to anglia house,going up there with a fair bit of shopping my current tdx sp goes up there with no issues, my small travel chair in my car is slow going up there and its motors get pretty hot..

The dealers only have access to a low powered "dealer" level programmer. That may do all that you need, but its highly unlikely that they will have any clue how to program it in a way that you need. But if you are happy as it is, and are not too heavy then it will likely be fine. Many on here are control freaks like me. Would drive me mental trying to use any chair I couldnt fine tune properly myself...

2 pole... And low power electronics, amd small batteries are again OK as long as you dont replrogram the thing to jump or steer on comand, and are fairly light and the chair isnt too fast. Its a price you pay to lose a couple of inches in width and a few k on the cost. It wont have as much torque, or range, and will wear out motor brushes and esp batteries a lot faster - if you use it hard. Hill = hard though. Hils and a responsively programmed chair, heavy users, all = hard. Thats bad on small batteries and 2 pole motors.

Everything is a compromise. Width and cost and weight is better. Performance (torque/range/battery life) and control (with prides control systems) because of locked down programming is the downside.

well it seemed ok on my trek round bungay to beccles, the hills were ok as well.. I need a narrow chair for my doorways. covered by warrenty and breakdown so if it does break down then they gotta fix ir or replace.

well i got a brand new one with ilevel which seems ok for what i want it to do,i got a few program names changed and i got hold of a dealer programmer which does a few things but not everything as lock outs i had to get them to do,I wanted ilevel to go faster when high and changed the colors,decel and accel parametrs, so it dont act like i am drunk. i left one with a small delay for indoor and resturants in case of waiter or carer knocking my joystick..am happy with milage as i done 44miles so far and am getting 12 miles on a charge but thats without worrying i will run out so i could proberbly do more miles but dont fancy pushing it, led lights are ok but a bit pants in the real dark on the front so am fitting brighter lights up front so i cant see the paths, goes over grass pretty well but i think it will get stuck on real rough stuff, goes over local skatepark ramp and i havent tipped it over yet. adjusted the suspension as it was to hard but no rocking chair sort of thing, i moved the seat back a little as itwas to far forward, only get a little fish tail if its a rough path but there isnt a gyro on these strettos, threw the original seat belt away as was pretty pants and fitted my own retractable type one so no dangle of belts on the floor or under wheels.. I will update if it breaks down but as its covered against that if i do kill it I will get it fixed, oh and dealer says it is available with 4 pole motors but thats only on 14" wheels versaion..(but he say if i kill mine they will see about upgrading mine to 4 poles)

Was your dealer willing/able to remove all delay on a quantum?

To do that you need a OEM level programmer. The dealer cannot get one in normal circumstances. So even if the dealer knew how and I seriously doubt it, he couldnt likely do so. Its only possible to do so much, but cant tweak motor compensation or remove settings walls etc.

well yes and no... I got the lift creep removed so it will go quick in the lift position but its not recommended as it moves forward a lot of u brake hard..I got it to turn better but its not 100% as Burgerman say I need aOEM programmer which is super rare to get hold of, I got a dealer programmer but it dont remove all of the delay in turns on the spot .. But I am happy with it and for what I use its ok for me...It goes through my narrow doors fine and in my car ok as well as on the bus and around norwich city fine.... I have one or 2 moans about the chair but they are minor.. I had a headlight led go funny after a month of use which was covered under the warrenty and I have just about killed the batteries and in the next month I am getting the dealer to fit new ones(I dont pay for the batteries) the wheel arch led light egg style switch is crap as well.. I added my own usb plug so i can charge my phone and bluetooth speaker on the go... oh and I dont get stuck to much on dirt footpaths unless its really wet,I can go over my local graveyard grass ok. I had to back off the springs a bit as I am only 70kg and it give a much better ride.. If I could I would of built my own chair but it would have to be a narrow type and use a controller/joystick which is easy to program along with lithium batterys
