What are yours?
Can the quickie have turtle shut off (by us)?
Yes.
My chairs are the older sunrise chairs, inc the Salsa (r-net) and and my newer Q700R. But that doesent matter. Anything - any chair with a normal generic R-Net system that uses R-Net (not permobil) components only can be completely programmed and changed in any way you want with an OEM programmer. With permobil you may or may not be lucky.
Unrelated. However:
Incidentally this vid at 29 mins, shows the problems with all front drive chairs regarding stability. In this case a permobil. As long as you continue to use the stock programming that I refer to as pudding steer mode, its almost ok. Because the delays in turn acceleration and deceleration disguise in mostly. But no way I can live with that. Once you know better its abysmal. As soon as you turn up the turn acceleration settings so it responds in almost real time, then it becomes obvious. Anyone that has never experienced a properly configured control system that gives you easy linear and proportional control will tell you its fine as it is. But those that have will never want a chair any other way. But if you do that with front drive the stability issue overides your new control and it all becomes a mess. You cant beat the physics. And when e says the stock programming on the f5 is better he is having a laugh. I have seen the turn acceleration/deceleration settings. To me those settings are what I call "hovercraft" steering... I could simply never live with that. This vid from 29 mins begins to try to show this.

I have tried them and its all too much of a compromise on control for me. Also dont like that long chair swinging about behind me battering things in tight spaces and running over peoples toes as you move about in a crowded pub for e.g. Rollin Positive will be along to say it doesent do this. Even though this video plainly demonstrates what I am saying.
