So if the Front Wheel Drive setting is zero, this is ignored. So set from 70 to 0 and test.
If Front Wheel Drive Type A, this parameter electronically alters the shape of the joystick gate. This has the effect of damping the turning rate of the wheelchair between the 9 o clock and 3 o clock joystick positions.

If Front Wheel Drive Type is set to B, this parameter sets threshold which, if exceeded, then both forward and turn speeds are reduced, but the turning radius of the wheelchair remains unchanged. Type B can be used to increase the steerability of the wheelchair at speed.
IGNORE THIS IT WONT BE USED
11.12 FRONT WHEEL DRIVE
Front Wheel Drive adjusts the operation of the specialist software for Front Wheel Drive Wheelchairs.
This selects specialist software for front wheel driven wheelchairs.
The programmable range is 0% to 100% in steps of 1%.
If set to 0%, then “normal” software for rear wheel driven wheelchairs is employed. MINE WAS SET 50% AS DELIVERED NEW!!!
If set to any other value then front wheel drive software is employed. A higher value makes the software more suitable for faster wheelchairs.
11.13 FWD ACCELERATION LIMIT
FWD Acceleration Limit sets the limit of forward acceleration when exiting a turn.
This limits the forward acceleration of the wheelchair when straightening out of a turn and helps prevent loss of traction.
The programmable range is 0% to 100%.
IGNORE THIS IT WONT BE USED NOW EITHER
just change the 70% down to 0 - and thats it ?

I think a lot of that might be just what you've become accustomed to. I know that after a day driving a forkllift (steers from the rear but powered from the front), I have to be more careful driving home in my car.
short bursts such as crossing a street, and it feels decidedly squirrely.

No. A fork lift has directional rear wheel that control the steering. They are not free to overtake you.
A better analogy is to do any of the following.
1. Set your rear drive powerchair so it can go 6mph in reverse. I challenge you to exceed 3 ever without losing control.
2. Fit CASTERS on the rear of a front wheel drive car. Try and drive in a straight line, and better, try turning... Too complicated to do but use your mind!
3. Take any manual wheelchair. Push it across a car park and let go. It will travel in a straight line, even if you attempt to knock it off course it will then straighten up naturally. Now turn it around so the casters are at the rear, do it over again to simulate front drive. As you let go it will try and turn around and go forwards again, every last time. You cannot defeat physics. It will not roll far backwards!
The student gets going with the system locked, starts a turn, and the instructor releases the lock so the fun can begin...
