Walkera WK-7.6-5

Application(s): Walkera CP RC helicopter

Comments: Terrible servo. The cheap nylon gears stripped on all three. The 7.6.9 replacement uses metal gears, but are expensive for what they are

Application(s): I use those servos for my walkera cp master helicopter.i have abuot 16 but none working.

Comments: servo are too bad .no gear replacement I had 2 cp master and spent too much money to buy a new servo, no waranty due to china. so dissapiont with walkera.

Application(s): Walkera Master CP

Comments: Trash, Basura, Lixo. This servo is absolutely worthless.

Application(s): Walkera V400D02

Comments: The V400D02 was my first Walkera purchase and my first 3D heli. The front servo stripped out before I even had a chance to fly it as the weight of the rotor blades seem to have stripped it just in moving from the box to my workbench.

I'm baffled why there is no reponse from Walkera on this. Unfortunately all the rest of the V400D02 appear to be excellent.

Will probably be my last Walkera purchase. I can understand an oversight, but continuing to simply ignore the problem is unacceptable.

WALKERA please listen:

1) I'd be HAPPY to pay for some better servos at this point. How hard could that be?

2) I'd even be pretty happy if replacement gears were available somewhere. They are easily replaced in only a few minutes.

Application(s): Walkera V400D02 Helicopter Servo

Comments: Do not buy this helicopter until Walkera replaces the gears in the servo. They strip immediately during calibration, a crash, or during flight. Worst disposable servo ever. Walkera has had one year to replace this servo. Do not purchase the V400D02 helicopter unless Walkera makes good on the servo. It is nothing more than a money pit. Walkera knows this and is intentionally stealing money from it's customer base.

Application(s): Cyclic servo of Walkera V400D02

Comments: Terrible servo.

The gears are so week. One new servo arrived with the gears broked. The other 2 servos gear set in my heli failed during the first fly.

Why these so bad servos cost almost $30?

Application(s): Servos for walkera V370D05

Comments: I lost already 8 servos in about two months. I's crazy! They are bad plastic and I'm feel loosing my money.

Application(s): Bad servos on V400D02

Comments: Demaged 5 pcs withing few meters fly ! I think that this servo needs tomake plastic gear wheels from ertacetal. It very solid smoothplastic material. Same is true for main gear. Valkera should do something on these issues.
!!!!!

Application(s): Came on my V400D02

Comments: Had to be the worst servo ever made. I have already gone through 9 sets. At any time the servo will strip which causes you to loose control of your heli. They need to make this site servo with metal gears. I'm done replacing parts on my heli and I'm hanging this one up on the shelf until the come out with a replacement that won't cause me to loose more money that I already have. Sorry, it's not a good review but look up Walkera V400D02 servo problems on the internet. People are crying out for replacments with very little MOD to their bird. I tried sending emails to Walkera, but the language barrier seems to be a problem.
