RE: semi semitrical wing chariteristics
Pretty plane - good colors.
Did you cut the wheels down or did you find some like that?
I'm still voting for CG. I had a Das Liddle Stick .20-size that snapped at the top of loops and whenever it decided it wasn't going fast enough. Takeoffs were a sometime thing but landings were always on the mains and as fast as I dared. Once in a while she would stay down on the third bounce (some of youse all have seen my landing skills).
I eventually moved the weight forward in little steps until it was closer to 18 - 20 % I think. As soon as I could show my clubmates that she flew OK I sold or traded it (I don't recall which) - it just wasn't fun anymore. Too many bad memories I guess.
But stick with it and you'll be able to walk tall, hold your head up high, and stride boldly into the sunset whistling the theme song from "12 o'clock High". Or at least have something to tell your grandson about one day.
