Similar rule is used at the worlds.

Like that one. I use a sub-plate to retain the front and rear gearboxes so I can change at will from 2WD to 4WD/2WD by swapping the gear casings and suspension and retain the same chassis. How do I know I would like this rule? It's been done before!

Correct! Modified refers to the definition of the motor in use, not the chassis in use. There used to be a Stock class in Off-Road that was for sealed-can motors. It died out for too many reasons to bore you all with here, and Modified was used all round.
'Modified' comes from the practice in the late 1970s of taking standard (Stock) Mabuchi and Igarashi motors apart and rewinding and balancing them - modifying them. This was given the boost it needed when Yokomo came out with the first open-brush endbell motor.

Maybe it should say that we can not have a second gearbox in a 2wd car. Dont know how to school this to be honest  |
Another good try, so I'll just use flexible drives directly to the wheel concerned and then take them out for '2WD'. Since there is no gearbox housing it's a 2WD car. Alternatively, I could design a system where there is no gearbox as such, just a hole into which I can bolt a separate housing which contains all the inputs and outputs I need to make it into a 4WD car.

Also i like the thought of banning extreme mid motor cars with a maximum distance foward a motor can be it seems the brca have let the rules for buggies slide and still strict as ever in touring cars and such classes

As for the first bit, look at your own rules as in the quote above. There is no restriction on the chassis design at all for a 2WD car within the dimensions in the rules. A 4WD with the shafts taken out is a 2WD car from a rules perspective!
I am trying to point out that making rules to stop this practice is very, very difficult; not trying to ridicule the posts or posters. As MattW said earlier, most, if not all of this has been done before and there are plenty of people who know how to tae a rule book and work around it. RC is as full of Colin Chapmans and Adrian Neweys as full-size racing!
I could not agree more with your second comment! We get some stick in the 12th Section for having strict rules on body shells, blinky speedos and the like. But, we do not have a bastardisation of our cars (LMP and GT) that flies in the face of the rule Off-Road has "Cars entered for Off Road competitions will be reasonable representations of full size cars generally accepted as being suitable for Rallycross, Rallying, Trail and Desert races." - a cab-forward complies with that??!!!
I think it is significant that your Section is one where the Construction Rules come after all the reams of stuff on who the Chairman is, how the Committee is run and how you run your meetings. Maybe this situation arises because your Section has got its priorities in reverse?? Just my thoughts...
This is a great debate - thanks for letting an outsider have a say or two!!
