RE: Warplanes
In general Warbirds don't make good second type planes. They tend to be heavy for their size and the flying speeds need to be kept up to prevent sudden stalls. For reasonable second plane warbirds look for the words "sportscale". They have larger wing areas or larger control surfaces or a different wing type making the plane easier to fly than actual warbird scale planes. The GP P51 40 kit (not the arf) makes about as good a warbird suitable as a second plane as you can find because it is relativly easy to build and fly. Other than that for a second type warbird I would check out the World Models warbird ARFs or Seagull ARFs but, there isn't much building involved. [8D]
