Why are we not considering a rebuild? One wing half is easily repairable. The other .. Well you could build a new one.. Or buy a wing that fits the thing, build up a new tail, repair the minor fuse dings and fly it again!

As for the second plane, I would say that has got to be your call, with what little solo flight time you have I would not likely do it. I solo'ed early this summer and Im not thinking Im ready yet, if you want to use that as a barometer. Just take the advice given in the spirit it was meant, or should be meant and then make your choice.
(My "Second" plane will be a SPADStick, I dont count the Debonair I built for the kids since its just another trainer. I wont have the stick built and flying till next spring...)
