Cheers everyone again, for your responses! I have only four digital cars at present: Two Ford Escort Mk1s (C3635 and 3592) Two MGB's (C3270A and C3631) All have 'reduced magnets' in them (I have snipped the ends off the regular bar magnets and glued them in their original position). There was a similar harsh braking effect before snipping the magnets, but I can't say that I have detected a significant change. It might be worth mentioning that the Digital Plugs are all brand new, coming direct from Hornby in a new batch (they were out of stock until March). The new plugs look different from the ones previously pictured on the Scalextric website, Amazon etc. which had a large cylindrical part on them, which is now absent. Maybe there is a difference / differences between them? BTW do ideas and suggestions from this forun get considered when the App development team meet? And if / when the App gets updated are there / will there be notifications here / elsewhere as to which issues have been addressed. Thanks again everyone!
