Why my PicooZ Helicopter flies on right circles?

Question

i do trim it to the limit thah will turn left by its self,but still it flies on right circles.should it be like this?is it possible to fly straight?

Answer 1

It is possible.

But not likely.

I have worked on a dozen of them, and our RC group has has about 30 or more of them.  A lot of fun if you get one that works.  But we had a 50% failure rate.  Fully half of them spin in circles forever.

There are some mechanical things you can check.  The tail blades break easily.  Just the smallest crack in the base of a blade will make the tail rotor less efficient.  The kit comes with one replacement, and more can be purchased online.

Also, if a hair or thread, or even a piece of spider web gets wrapped up in the tail, it will not spin freely, and the heli will spin.

Good luck!
