Problem is I think that will be too tippy for me especially to tilt being a c4/5 quad.

As I keep on saying to people do not ask the "experts" use your own brain. Because they just make shit up to cover their ignorance.

As I've mentioned my main concern is not tipping back as if I go with a Q700R I'd want a center footplate.
As I've been using a mid wheel chair, tipping over is not a problem when tilting.
Is shifting the seating back on the Q700R for CG or because a middle footplate won't fit otherwise.
I understand BM you believe they are to noise heavy if it's not shifted back, and don't drive right, but just curious to know why or if it's essential?

Been a long time since I've used a rear wheel chair. It was what I felt most comfortable with, but then in Australia for a long while rear drive chair were lacking in the choices, and mid drives are pushed hard.
I do like the ability of mid wheel to spin on the spot, though when I first jumped in one it felt like I was doing fishtails all over the place.

LROBBINS wrote:Yes, that is how it should be. Motor speed is controlled by voltage (using pulse width modulation). When just starting out is rotating very slowly - low voltage, very high motor current, much lower battery current = motor current X PWM percent.
Burgerman wrote:The controller limits the CURRENT to whatever is programmed as maximum. So the voltage cannot increase as the current would rise above the maximum. The voltage or rather the pulsewidth is the thing that the controller is reducing in order not to exceed the rated current.
Since the motor is also a "generator" as the speed increases the current naturally drops and then the controller will use a higher pulsewidth to maintain the rated current.
As to why your motors dont turn I have no idea. What is stopping them? Do they have too much load? Brake is on? What is the motor fitted to?
LROBBINS wrote:You might also be able to reduce the rolling resistance of your tires and/or reduce the torque required to overcome the obstacle by shifting the center of gravity.
If pneumatic tires, you can reduce rolling resistance by increasing tire pressure.
Shifting the center of gravity rearward will reduce the load on the front wheels, making it easier to get them over the obstacle. If your chair has tilt, you can see if tilting back shifts the weight enough for this. If not, you may have to move the seat back - easy or difficult to do depending on design and possible interference with foot plates.
BTW, if you turn around does it more easily climb the obstacle going backwards?
