Bought a used E-FLITE S 15E Apprentice and Spektrum DX5E radio. Preflight revealed both aileron servos travel together. Either Flaps or Air-Brakes but no turning. Right servo (from behind) appears to be the Gray Original servo, but the left one has been replaced with one that has white+red+black wires (Futaba?) Both are hooked up to a single channel with a "Y" harness. One servo is mounted on its Left-Side, the other mounted on its Right-Side. Looks like this should work causing ailerons to work normally. Are Futaba servos wired to run "Left Handed"? Anyway I cannot find replacement servos anywhere. Does anyone understand ***, or where I can buy servos for the Apprentice? HELP. . . .

The Futaba servo probably operates in the opposite direction of the original servo. Not all servo brands operate in the same direction.

If you can't find another original equipment servo, purchase a duplicate of the Futaba, and replace the remaining OE servo.

Or reposition servo arm 180 degrees and move the horn on the aileron.

Also you can buy a servo reverser for 6.99 $ Servo Reverser Y-Harness

THANKX Tom, Thatz what I suspected but needed confirmation. I'm going to replace both since this thing is used. I don't want to lose a plane to a cheap servo.

Are both servos the same brand and model number? They need to be. Are the servos hooked up to a reversing Y? as far as mounting the servos need to face either both facing in or both facing out
