Dear all bro

Need help from expert

My F15 eagle from starmax

Why i power my throttle, one of my left wing elevator also up/down like crazy?
And after i off my throttle, the left wing evaator cannot function?only right evevator can use only?

Why?

Anyone have the same experience here?

Pls help....i new here

hmmm

i'm assuming u r not using y-cable for yr elevators. make sure yr mixing is right. seems like u r mixing throttle with yr left elevator. use channel 2 (hitec/futaba) as master for 1 servo and aux channel as slave for the other servo and mix p-mix them. hope it helps. better to use a y-cable so that u dont have to mix anything.

hmmm

if u r using y-cable, make sure its not between yr left elev and throttle. it shld be between yr left elev and yr right elev

Seems to me like the left servo is gone... Try switching the 2 elevator servo channel to determine whether is it really a servo problem.
