'I 3D printed a phone stand to put the phone above the track'

i used the bendy clamp in the track picture , and realised a phone stand over the track would be the way to go , much like a light bridge ... great minds   .. Tinkercad here i come 

'My little TR7 continues to go well, but the Ninco Focus seems to be struggling a bit'

yep your TR7 goes better than mine m8 , but they are always going to play 2nd fiddle to the 914's , as for the Focus , it too is up against alot of lower COG cars  ... maybe we should rethink our choices , nostalgia isn't winning for me
