Silvaire, Yes, I actually do have one of those Competition models SST kits in the attic, and I also have a set of the B-70 plans. In fact, I'm working on a SPAD version of the B-70. It will be 6' long and use a K&B .61 pumper for power.

As for the SST I was talking about a different kit Lynn S and I have (actually, I have 7 of 'em in 4 sizes)
