So I had installed an Oxigen chip in my Scaleauto Porsche 991 R-Series car...
But the 'packaging' of the chip was not very neat due to the bulky front end of the Scaleauto motor mount stopping being able to lay the chip flat on the chassis and requiring the use of a remote IR LED...and that was niggling me. So the obvious thing to do was to change the motor mount to a Slot.it version as the front end of those leave more room to lay the chip flat on the chassis floor. But whilst it might have sorted out business at the front, the new mount was causing chaos at the rear!
Firstly the SI rear axle mounts are spaced further apart than on the SA version. And secondly, the SI mount seems to position the motor slightly further to the right hand side of the chassis compared to the SA one. The result being that the pinion gear and the anglewinder gear no longer met, and the body did not seem to fit properly around the motor. Having swapped the SA mount back in to sort out the rear end, I could not go back to the ill fitting digital chip, so the SI mount went back in and a decision made to 'follow' the problem through at the rear end to try and sort it out. So as a first step, I have just bought a new (SI) motor with a slightly longer shaft which hopefully will allow the pinion gear to at least reach the anglewinder gear and hopefully mesh together as they should do.
Was I being a bit naive to think swapping motor mounts between manufacturers would be a straightforward exercise?
