If Denis is satisfied ..then GREAT!but if it works the problem is solved!

but going back to the steering is reversed by turning left goes right and vice versa.
I think that Denis was complaining that the mechanical steering on the 4WD chair WAS behaving like a car, and not like a wheelchair. He wanted it to behave the same as a wheelchair, stick right = nose right whether going forward or backwards, rather than as a car, steering wheel right = nose right going forward, nose left going backwards. He has achieved this by electronically flipping the signal to the steering gear motor (a fifth motor!) when driving in reverse.

I am sat in a Sunrise F75S (with Recaro) [same electronics as F55S] using P&G, and it behaves exactly that way!
Joystick back, goes back; joystick back and to a side - chair turns in the opposite direction to the joystick pull; pull the joystick back and left; chair goes back and right!
If I pull my joystick back and to the left, both my chairs roll backwards and to my left (my left as I am facing forwards). My feet therefore swing around to the right as I reverse.
... If your chair is turning to your left surely your feet follow and turn with you?I pull my joystick back and to the left, both my chairs roll backwards and to my left

"Penso che Denis brontolava che lo sterzo meccanico della 4WD si comportava COME un'automobile invece che come una carrozzella. Voleva il comportamento uguale alla carrozzella tipica: joystick a destre = "naso" a destra sia muovendosi in avanti, sia muovendosi in dietro, invece che come in una machina: volante a destra = "naso" a destra andando in avanti, "naso" a sinistra andando in dietro. E' riuscito a farlo invertendo elettronicamente il segnale al motore dello sterzo (il quinto motore!) quando è in retromarcia."
it is so!
Another thing I would ask you where to buy two oil shocks absorber with adjustable load long approximately 19cm.

Ashley ,
I'm fascinated by what appears to be two different joystick control modes....this may explain the problems I've previously had trying to "fix" / trouble shoot motor direction and joystick combo's via the web...by erroneously assuming that the joystick control / direction was universal.
Could you tell me where "spin" ( one motor fast forward the other fast reverse ) is on your joystick .... in fact a "map" of your joystick knob position versus motor directions would be appreciated!
