You went up that mild slope and lost control? Thats what normal "safe" powerchairs do.
As I have mentioned before. 99 percent of powerchairs go where they, or the feeble elecrics and awful programming let them or make them go. Not where you wanted to go. Making then steer and drive accurately is easy, but for reasons better known to themselves the manufacturers just dont do this.
In any powerchair, if you want some accurate sensible DIRECT and controllable power and steering you MUST make sure you have the following correct (for a normal grown adult):
--The best 4 pole motors of low impedance you can get on your chair.
--6mph maximum, more is a disaster for control in difficult situations. Less is dangerous.
--Heavier/shorter cables (battery and motors) than any manufacturers currently fit.
--100 amp or better controller.
--Controller MUST be programmed as per THIS page - all of it - (essential): http://www.wheelchairdriver.com/powerch ... amming.htm
--Mid drive, or rear drive with C of G moved back so the chair is responsive and most of your weight is on the drive wheels.
--LOW impedance batteries like the Odyssey PC1500, as MK Gel or worse just doesent cut it once you do the rest of this list, the batteries become the limiting factor, if you want great control on ramps or in difficult places.
Do ALL of the above and your chair will drive just like a PC mouse, or a car, or your pencil on a page. It will simply go exactly where you intend, without a thought. You will never think about it again. It goes straight when you tell it. It turns when you tell it. It STOPS turning when you tell it. It climbs when you ask it to. Its just becomes easy
transparent and normal. and you simply dont think about it. NO stock chair is like this. To me they are all unusable and dangerous. Dont
do ALL of the above, and just go wherever the chair decides to take you. Most dont realise how good it CAN be. If you are reading this and thinking your chair already goes where you want, then you simply have no idea.
