Why permobil make their own frankly worse driving stability system (gyro). They seem to be mostly used in the US even though they are made in Europe.

Read lower down.
The R-Net in house Gyro, thats plug and play and works with the normal "speeds" programming in the R-net programmer is:


PRODUCT CODE
R-net Gyro Module
Note: Not available for sale in USA, Canada or Australia.

Are you tempted ?

[Burgerman]

No.

What is wrong with the gyro Permobil uses in the US? I haven't had any issues with my 2018 F3, but I have heard they changed model due to parts shortages. When I tested a prerelease power platform F5, the turning was set painfully slow. Not sure how they are now.

They dont seem to have as good steer/correction algo. They also use a different additional section for the speed settings that is lower down the menu too. And the two different sections dont play well together. And no matter what you do they drive like someone else is doing it...

Part of that is the front drive instability and the system forces it to slow when accelerating away while turning for e.g. But the front drive chairs with a PG r-net gyro are easy to program in a way that makes it go where I tell it regardless - at least as far as front drive allows. And the settings are in the correct normal speed section at the top of the menu. BOTH gyros take away your control in order to use that power to stop the rear overtaking the front. So its all very non intuitive to drive because of front drive physics regardless.

Pre power platform chairs all had ESP apart from parts shortages during covid when the switched to rnet gyro. Rnet gyro equipped chairs don't drive as nice in my opinion.

Powe platform chairs have an rnet gyro built into the power module and is switched on of off via software.

Power platform chairs being the new permobil only version ones that we cannot program? Is that correct and what they are called? Never saw one yet.

With normal programming that I refer to as hovercraft mode they all drive so crap that you honestly cant tell which is the worst. I cant hit a doorway never mind front, rear gyro or not.

When I program them so that they actually steer properly, thats when you find out that this isnt possible with ether permobil or r-net front drive chairs. But I can get the r-net ones to at least resemble some control!

And

Difference is astounding...
Has already had the WCS experts to "program" it. What a joke that is.

That's what I wrote to Burgerman yesterday. He didn't tell you how computer illiterate I am, bottom line is didn't have a clue about the basics it felt like he was talking Chinese to me. But he got there, quicker than I expected

This is about my new WCS supplied Q300R which I've had for almost 3 months, I've only done 1.4 miles in all that time because the chair was horrible to drive and, quite frankly, it was dangerous. WCS have sent their 'engineers' out to my house to reprogram this chair on 5 occasions and made it worse each time, they've spent hours tapping away at hand held programmer and achieved nothing.

My excitement grew when I finally secured an R-Net dongle, after pulling my hair out I managed to send BM the file with the program from my chair. A couple of hours later I checked email and he'd done it, it did take me a while to upload it still not sure how I did it. But then, hey presto, I get in the chair and it's like a new one. It's fantastic, point it where you want to go and it goes ... straight through the doorways and around the tightest of obstacles. I know the Q300R won't win any Best Chair prizes but it's pretty good, much better than I expected.

A massive thank you to Burgerman for tolerating my stupidity and for turning a chair I hate into a great machine

WHEN trying to program a chair to STEER PROPERLY the permobil is literally impossible. It just gets snatchy and horrid. The r-net front drives are crap too, but at least you can get closer to the illusion of control.
