Krick has been my Go To supplier for several years now; rapid delivery, good service, reasonable prices for quality 'stuff' and if it says 'In Stock' on their website IT IS and is delivered in 2 or 3 days😀
I use them for materials, including the Deluxe Materials range (EzeKote and adhesives), Quikrun ESCs, Switchers amongst other odds and ends. Very happy with them.😊
Before BREXIT I used to use Component Shop for Action Electronics modules.
But now Customs delays and duty make that an expensive pain in the U know where!😠 I've since found a few specialist German companies that do similar modules and excellent smokers.
Peter; as requested I'll dig out some names and links for you - hope you're not in a hurry though! Are you looking for anything particular?
Cheers, Doug 😎
