Yeah, they keep telling me SPADs "bounce" but I haven't been that lucky. I had similar results with my Deb MKI. I had an old K&B 65 on it that I never could get tuned right. She cut out on me, but I couldn't really hear it because I was a good ways away. When it went down, out of ALLLLLLL that grass out there, I clipped the edge of the asphalt walking track. DANG! The wing survived though and I put that on Deb MKII and she's still flying sweet 5 years later with an OS46FX on it.
