Someone built a SPAD jet years ago but as I recall, it never flew.
You might be thinking of the 2 times "Sig Wonder" spad I had built in 2009, and indeed could not get to leave the ground. I think the high thrust line of the turbine wouldnt let it rotate. That one never did get airborne and I ended up giving it to a kid after stripping the airframe of the electronics and engine.
