Not seen this spring before ,good idea but i be watching it dont crack or break those plastic clips that lock blade with undue pressure might cause prop to fly off
is this replacing the spring clip idea
Ok thanks i do notice i have to retension my spring clip more often,,i got thousands of springs gona have look and mayby try if i got some ,thanks Ian
I think it just coating thats on spring slower coming off causing this residue .the spring spinning around on round shaft will do this,not expert on rust being a panelbeater but thats my 2 cents
Hi not sure about chemical test ,if spare spring the same avalible to you you could lightly sand or scuff with fine sandpaper,bit of water and let sit for day or so and see what colour wipes off it,,being a black spring its been hardend ,inside coil of spring probly bit lighter in colour than out side ,in you first pic you can already see coating colour change at top of spring where it goes down on prop...not being a wet rag i still want to try this method as my continued bending of spring clips says they need replaceing(like every 2nd flight),,
Yeh not the best colour on white i got time off today so i be in me spring collection ,is the white thing with 3 prongs on we spring sits the original or do i need some more looking at yours it has a resess in bott for spring to sit nice in
