Hi Mac,

I was using a OS.61FX. I was using a 12x8 prop when it happend. I used blind nuts to hold the wing. The bolts holded very well. You can see from the pictures, the block that supports the wing is still attached to the wing with the two nylon bolts in it. On this new build, I will not make any mods. I will keep using blind nuts though. But I will change engine. I think I will use the TH 0.75. Although I am a big fan of O.S.
