Everyone will tell you that rear drive chairs are worse indoors. And thats true of every powerchair where the seat must be mounted too far forwards. So that the normal
swing away footrests are able to clear the casters. They must be stuck ahead of the chair and in front of the caster wheels.
The result is a nose heavy chair that steers very badly and is too long indoors with your legs stuck out ahead. But a centre footplate cures the problem. If its small enough, it fits partly between the caster wheels. Allowing the seat and footplate(s) to sit around 3 or 4 inches further back, in a more reaward position. Which is why all my rear drive chairs use a centre footplate.
Search the web for rear drive chairs with centre footplate, its not common or easy to find! But you can push the manufacturers to fit the centre mount footplates that they normally fit to their centre wheel drive or front drive chairs. But they dont like it! Thats why you can't see a pic of a Jive/Salsa with a centre footplate and the same is true most of the other chairs out there. They think rear drive = swing away foot riggings.
However there can also be issues if you move the seat/footplate back to a more rearward position. Such as below. Note the shiny bolt sitting just behind the footplate in the exact place you do
not want it! It holds the actuator on... And hits the tyre.
Note actuator/bolt.

download/file.php?id=7610&mode=viewThis pic shows (rather badly) that the footplate actuator end attaches to the side of the footplate, just behind the plate itself. Because it was designed by an idiot. So if/when you move the seat back, this bolt is the first thing that is in the way and it hits the caster tyre preventing you from doing so. This bolt/actuator is the reason you dont see centre footplates normally fitted or mentioned on sunrise's rear drive chairs. But I am going to move the bolt, the mounting, along with the actuator itself slightly. By just half an inch and make it shorter by a further half inch by moving it slightly inboard... As the manufacturer should have done! And that allows the clearance needed for the 10 inch casters. If I fit 9, or 8 inch casters I can move the seat back another inch or so. Which will also happen eventually. I may also cut off the
rear corners from the over-wide footplate too. Allowing another inch...
