First twin kit???
If you don't mind ARF's then the Hobbico Twinstar is great, I fly mine on 2 .25 FX's and it is alot of fun. Well, actually I used to fly it with 2 .25's now it has three, but that's a different story. If you really want a kit then the Pica Duellist is a good one, or you could go to the Top-Flite DC-3 but that gets a bit complicated for a first twin.
