Please see Post 2343 for an option. Although I sniveled about having to use the scrawny cheapo "Radio Sherk" desoldering braid it has proven itself to be light weight, easy to work with because it's fluxed, and best of all it's rather thin so there's useable clearance between the bottom of the flag and the track/rail. Something I consider to be critical.
My personal experience with foils led me to seek another/better (?) method for dealing with the Tycopro's weakest link. Just never quite right ....ya know? ...and when it was right, one good crash and the foils are all kerflunky again. By creating a re-usable "carrier" for the braid, I dispensed with the foils once and for all. I just changed the prototype set you see in the pictures last night.
Remove the weight slug, uncross the leads, release the keepers underneath and slide the carriers out. Then desolder the old braid and attach a new one. Re-assemble and clip the braid to length with sharp scissors. We're talking under 15 minutes tops.
Other than an occasional maintenance teasing, they run flawlessly and eerily silent. So much so that I hadnt given them a thought until I saw your post. Best to read Grunge Rock Jeepers tutorials as well. We havent heard from him in a while but his tutes are required reading.
