Help - Mini CP

I recently purchased the Walkera MiniCP but it developed a fault, when I start it up instead of taking off normally, the helicopter vibrates violently. It eventually manages to lift off the ground but only by about 1 ft and even so it is uncontrollable.

I don't know what to do, any help?

Did you check all your swash links to ensure they are on the balls properly?

Thanks for the fast reply,
Yes I ensured to check all the swash links, they are on the ball joints properly.

Did you bend the feathering shaft?

You know there's a Mini CP thread where they discuss this model of helicopter and the stuff that goes wrong with it?

Sounds like main gear has slipped down. Just tap it back up all the way easy like.
I use piece of metal tubing big engough to go over gear hub. Turn heli upside down on firm surface and tap it down easy. Or like said crash may have bent feathering shaft.

I considered the main gear but I've never had that cause vibration, generally this just causes a lack of lift when positive pitch is applied. I admit that my experience with the Mini CP is not as great as Dan's so I'd heed his advice and check the main gear as well.

Yup, i also got this vibration on other heli when main gear slipped down during crash, just push it back and it should be fine.

Even a small gap in main gear will effect lift. Wobble is gyro is not happy as gear is moving up and down.

I'll look at the feathering shaft and the main gear. Thanks for the help
