been fixed for about a week but i went up and my plane was doing crazy things i wasn't telling it to do...so instead of losing it to a tree again i cut the power and let it come down...of course the tail end banged off the runway just missed the grass... snapped the back of the fuse. right where the tail mounts on..2 second ca glue fix...then i noticed my servo was searching for center a little to long..i guess you never know when a servo is gonna go bad..and tricks on testing them of ideas of knowing when there going bad ?

Read this and check it out. supercubclub.proboards.com/index.....lay&thread=1631Broken gears-easy. Doesn't work right after a crash, skips, and grinds. Bad Pot - starts to jitter while resting, assuming no binding of linkage. Gets worse with age. May start suddenly with a crash. The Cub may not be affected much with minor jitter. Sudden failure - pretty much impossible to predict. In the PZ case since the servo 'brains' are in the black brick, not the servo as in a normal 3-wire servo, if something goes wrong in the brick in can affect the servo. In the link above it's a connection problem to the brain and/or power. That RX/ESC brick in the Cub is sure a troublesome little POS. Trouble with your crash is you have what appears to be elevator issues but on landing crash badly enough to break off the tail which puts an incredible strain on the servos. That alone could easily ruin both of them. Now, figuring out what WAS wrong is close to impossible. |
