Cinestar 8 settings

[Msk383]

Hi, what kind of settings you are using in the cinestar 8 frame with mikrokopter electronics in aerial filming? I have some difficulties with wobbling and oscillations and I can't get rid of them. It's quite difficult to find some gyro values etc for C8 from the net because cinestar setup seems to be slightly different than what people are using in mk frames.

I'll appreciate any help, thanks .

Thanks, I already talked with Thiago and his video's was helpful. I got it fly better but still the C8 makes small oscillations, sideways, I think.. http://vimeo.com/39655642. It's annoying when you don't know how to adjust something! .

Tere, Siim! Your got your C8 flying pretty nicely. What PID you are using?

P 110
I 120
D 30
Acc factor 32
Acc comp 50
Dyn stability 65
Gyro stability 4
Stick P/D 6 and 8

P=120
I=110
D=27
ACC_Gyro-Factor=27
ACC_Gyro-Compensation=50
DynamicStability=70
Stability=8

And i use -60% expo (nick/roll) in Futaba Tx
But i am not satisfied yet ..

It seems that I have two engines with poor ball bearings out of the box. I noticed that the vibration has increased a lot after the balancing. Could be the reason for everything.. Well, less than 10 hours and I'll need replacement parts .

Does anyone know the part number for QC3328 bearings?

Same thing happend with my QC3328 motor.
Very bad quality-price ratio, like most of overpriced cinestar stuff...

Well, bearings are 694z EZO and they are quite cheap to buy from rcbearings.com and luckily replacing them is easy. It is cheaper to buy spare bearings than sent otherwise ok motors to States from the europe and wait one month to get the new ones..

High quality jap bearings, yeah right... Also the qc3328 seems to be made by tiger motors.
