Default RE: Cannot get wings to stop rocking!!

Hi guys,

I just got my turbine waiver, so I 've been kind of busy with my jet lately. In the mean time I've sent my DA-50 in for repair (bad ignition).

The gaps of all surfaces are sealed, and the elevator throw seems symetrical.

NOBODY here has paid attention to my question regarding prop size. You guys are getting way too deep into the little details thay are only good once the basics are estrablished. But thanks anyways. Once I set up my Harrier and get the wings to stop rocking I will pay attention to to Expo's, elevator diff throw, and all the fine tuning you guy's have mentioned. Im pretty sure that the wing rock is due to something very basic.

1. I will swittch to a larger diameter/lower pitch prop. I still think that the rcking is due to lack of prop wash underneath the wings and. anyway, that is just how it "feels".
2. I will do a lateral balance check. This model is an ARF so I don't expect one wing to be 1lb heavier than the other.
3. For the time being, ELE travel on hig rates will remain at 45 deg with 30% expo. Im comfortbale with it and the plane feels good.
4. Will re-check the CG. It may be too far aft.
5.WIll add a Sullivan Smoker, becasue it this piece of S$it will not harrier I can still fly some pretty neat figures using smoke.

I will let you guys know how the next fligght goes.

Thank you all for your input, Masters.

later,

Quique Somenzini
