    Well, it's mostly built, weather has kept me from really having a need to finish it.

    As it sits with no electronics it's under 4 ounces, should come in under 16 ounces with 2200 3S pack and Grayson super parkjet motor

    Ok, this is the first plane I have ever had flutter with so I am not sure what needs corrected.
    I do believe the control surface may be too big for this fast a plane, also I am not sure if the wing or aileron was the culprit.
    I guess I will make the ailerons a bit smaller and add another CF strip to the wing and give her another shot.

    Autopsy revealed that the servos are fine and tend to lean towards the fact that the Hobby City 9 gram cheapies would strip with flutter, so I am leaning towards the wing fluttering.

    Man O' man that stinks! It turned out really nice looking too.Well at least you got a couple passes in.
    Maybe you need another carbon spar?
    Just a thought
