I can'nt give you answer to your question if this would make a good 3D plane. 50 cc could be pushing it a little. On these SU-26's No replacement for displacement. I don't intend to do 3D. If I did it would be by accident. So far I have not run into any assembly problems. Most or should say all ARFs I go over the glue joints with CA. Wings are another question? Your on your own Grass Hopper.
Wild Hire or Aroeworks planes might be the way if your going the 3D rout. Good luck on your quest. I'm cheap and just fly Big Circles . Smoke -ON! Welcome to be GS gassers.
