Still trying to print better decals... In the meantime I decided to add driver cooling duct. I saw Alex Kustov method with teflon tape but decided to try differnet route. I used heat shrinking tubes. I used screws and my own cable threaded needle. Partialy succesful
Test 1 - on screw and painted with Tamiya TS paint
Test 2 - on needle
Test 2 looks better but not best - a bit out of scale. I will look for smaller screw and will see if manage to get better air duct.
