they work beautifully! thanks for sharing! it handles much smoother now it turns easier not so twitchy more predictable and still flies on rails! love this plane. just be sure the canopy is secure i lost one at high speed it ripped my plane to tiny pieces in mid air get a stronger magnet to avoid this. think it did lose a bit of speed though to the drag of the winglets. it is fine as i enjoy flying it this way better. if im on edge and its twitchy i don't have fun much my kid claims to love that part but me i want gentle predictable turns he like drilling it through the air lol. thanks again!
