I've not been on the forum for a while so I was surprised to see all the suggestions and comments, even if some of it is over my head. Thanks.
So far I've changed the braids on a couple of cars, cleaned up the track a little and that has made some improvement, however its still seems down on power to the Scalextric Sport power base I was using prior to getting the SCX Chrono.
I'm swaying toward the copper tape at the moment as it seems like it may give me the best results for my setup. I still need to check/crimp some of the joints but some of the track is fixed to the board using Scaley fixing clips so I'm loathed to pull it all up...........but I may have too.
Any recommendations on copper tape? (UK suppliers)
