Blade 130x cyclic rotor head wobble , any ideas?
I wonder if you could help.

I'm playing round with my blade 130 and 90 % of the time it flies great. Then, randomly it appears, it simply develops a violent head wobble and lurches back, pitching.

On respooling it has a different headspeed too often.

Its completely standard set to default manual settings. It does seem worse when outside in the cold and when there is a bit of a breeze

Any help is appreciated

You cold try different o rings in the head, maybe they get hard when cold...

Or could be a bad servo for the pitch acting up once in a while if it always pitches in the same direction..

I've only had one servo go out on me, it went out of trim, I landed re adjusted the trim then it went out and rolled into the ground in a turn..

on mine..
It worked best if the blades were just loose enough in the grips to pivot without any resistance.
I do a great decending funnel!

If I remember right the main shafts is a carbon type material that splinters and is sometimes hard to tell it is cracked or splintered. Just something to check, not sure if it would give your symptoms.Blade 130x (5)
