The Force Four wouldn't win a beauty contest, but its a Chris Foss design, and his stuff always seems to "fly right". I was thinking about time available when I got down to looking at the Force Four. It looks as though it would be a really easy and fast build, and I've the bonus of enough balsa sheet and a few servos looking for a home. Years ago I bought the plan of Chris's Phase 5. I never made a start on it, but sometimes I'd lay the plan out on the floor and just look at it. In my opinion, the lines of the Phase 5 are splendid. I passed the plan on to a fellow modeller. Now I wish I hadn't, there's an enterprising chap on eBay who sells sets of ribs, not just any old ribs, he includes ribs for Phase 5. Think I'll stick with the Force Four, easy and cheap. Has to be, I'm saving up for some big batteries.
