Diana, I have had one about a month. It uses the mercury switches and has too many safetys for my taste. If you have the tilt in space it won't do it with the wheels turning. The other drawback is the slow braking. When I let off the joystick I want to hear a click. even turned to turtle it seems to have a lot more power than it should. It has stable tracking for a six wheeler and can handle modest off road. Be sure the guy with the computer programming tool gets you adjusted before he leaves is my #1 recommendation. If you don't fly, ask them to only put in maintenance free 24group deep cycle batteries. You don't need to pay double for gell cell batteries with half the power and life. If you aren't aware of your legs in space, get the leg guards and full size footplates. They are much easier to fix than your legs are and the chair can be incredibly powerfull. It isn't bad for a bottomline chair. My old TDX got to where it burns out potentiometers easiy, or constantly. Remember, this chair has to last seven years. It will need you to take really good care to milk that much from it.
Good luck, john ________________________________ From: "diannal...@aol.com" <diannal...@aol.com> To: quad-list@eskimo.com Sent: Wed, October 21, 2009 6:33:22 PM Subject: [QUAD-L] New wheelchair Hi all, I'm due for a new wheelchair & I'm looking at a TDX SP.
