Full height spars is pretty much a given, I agree. I would have expected the crack on the bottom, looks like it on the top. I have a lot of experience with probond and gorilla glue. Probond was used on a wing mfg P-38 foam wing sheeting years back, love that stuff. Gorilla glue was used to build my airplane trailer. I will probably do the spar fix early on. It doesnt sound like a big hassle. Just cut a slot, stuff it with spar, fill it with polyu glue. I learned that its much easier to wipe off the expanding glue as it happens within the first hour. The probond dried pretty hard and had to use the dremil to remove the excess.

Robert,
I already have the kit.
