I think I am right in saying that the pride "q logic" is just the R-net penny and giles system rebranded for them. Is this correct? New plastics but same old p and g electronics?

[Swan T.W.]

I am pretty sure the Pride Q=Logic is Curtis.My R4000 100 amp Q-logic is Curtis.

We are scheduled to demo a Quantum R4000 this month- I will post whatever I can learn from it.

[Burgerman]

Interesting and please do! In that order. I presumed that prise and p and g were close partners so that it would just be different plastic.

Do curtiss do anything bigger than 2x 100 amp? Ot that will work with 36 / 48v?

[JoeC]

During my inquiries I learned that the largest Curtis brand controller (for chairs) is 2x75 amp. That doesn't rule out Curtis as the OEM, but I suspect that I will find P&G with 100 splir between the two.

My main concern in the chair demo will be the durability and effectiveness of the suspension and power seating, but will examine the rest as well.

I will post whatever I can learn from it.

I think you will mainly learn that its big, high, nose heavy as hell making it feel longer and worse indoors than it should be and has a fairly harsh ride and is programmed rather badly. Programming can be fixed at least if its p and g in disguise. If its their really their own you will struggle? But I dont think they actually make their own. Is it 8mph? That could work ok as your wife is very light?

Oh and DO investigate that swing away thing!!!

Pride rep in my area said my Pride r-4000 has Curtis controls, 100 amp controller, compact joystick. It's extremely nose heavy,very stiff ride. Have not had any success with programing it yet. Would like to try putting 3.50x8 tires but don't think there is enough clearance. Plastic receivers for armrests and legrests are a very weak setup. Armrests have to much play and the legrest receivers get hairline cracks, that are covered up by a piece of rubber. Most people would not know unless they remove the rubber cover. Metal and plastic at stress points, what were they thinking?

Curtis has a Enable 40 system. 75 amps and a Mc-2 100 amp dual motor system. My chair has the Mc-2. Joe will let us know which one is on the chair he trials. Hope this helps. Burgerman by swing away thingy do you mean the joystick? If so, good luck figuring that out. Joe, there is NO suspension.

Regarding balance and weight distribution, size, and height- as long as it is no worse than her Invacare Ranger X, then it is no problem. The thing that will most improve her comfort and independence will be high quality powered seating. If she could get the seat elevator and elevating legrests without requiring a slower chair or a huge payment from us, that would be on the table too. She weighs less than 100 pounds and only travels in areas that are well served by punctual and accessible buses and trains, so battery life isn't the same concern for her that it is for you.

She would love to get the 8 mph, but we are not yet sure what we will have to pay over the base price over the chair. It shouldn't be a dime more, since we know that it's just a motor with a different winding and no other mechanical considerations.

She won't accept any chair that's any larger than her present one, not in any direction. She also won't accept a chair that's any slower than the 7mph she has now. She is good at being assertive about what she needs, and thinking through the tradeoffs to understand what she's asking for. It is my job to make sure that the chair she gets will be more reliable than the one she has now.

With that in mind, I will be carefully inspecting all of the mechanisms and stress points, trying to figure out how likely the chair is to destroy itself while bouncing over sidewalks and otherwise being used normally.

Thanks for this!! I will be look at this early in my scouting. Aren't foot rests regularly used to open doors that aren't powered with a button? I know almost nobody in a powerchair who doesn't do this.

With no suspension, that chair just lost a lot of reliability points! I don't care how much loctite you use, sidewalks just produce far too much shock and vibration for a chair to survive without suspension! (The large pneumatic tires will do the same, but we've already been over why she won't use those) That chair just lost a lot of points- if they don't ship us something substantially different than you described, then she's probably going to end up with another Invacare.

However, the MC-2 intrigues me for other purposes. Thanks for mentioning - I will investigate further!

Found an MC2 datasheet from 2001:

It's interesting, but for now I'll stick with Dynamic for my high-power needs.

As far as I know the other sister chair the Q6000 has no suspension either. Only sprung caster arms. At least thats how it feels in my street! And it hurts. Or that could have been the solid (foam filled) tyres. But I hd to go pretty slow to stop my spine taking lots of shocks as I went over different sections of concrete road joints.

My previous chair was a short wheel base Arrow Storm with GB motors. The R4000 with lift and tilt fits the about the same footprint with some do it yourself mods. Could be smaller if you shorten up the anti-tippers. Even more so if you take off the useless [in NA anyway] 10 lb battery door and replace it with a piece of abs or aluminum. If i can come up with away to put larger tires on even if i have to use the stock rims, removing the door would be next. You couldn't open a door with these legrests. I ordered the HD legrests which are all metal 90 days ago. Still waiting. I just want them for template. A shop that does boat railing and cabin fittings is going to make them up in aluminum or stainless.

Burgerman. Try this for a swing away joy stick mount www.retract4.com.

Better but still looks like it will be weak or wobbly. Maybe not. But its closer to whats needed than that huge jigsaw puzzle that pride made!
