Its not what was left out of the Venture but what was added to the 4 Star 60.
Like w8ye said Bruce Tharpe designed the 4 Star 40 and 120. The Venture
wing is more like the 4 Star 40 or Midstar wing.

Additional structure was added by the designer of the 4 Star 60 that
Bruce claims is unnecessary. I dont have any first hand knowledge
of what that structure is since Ive never built a 4 Star 60 but I have
dealt with 4 Star 40s and a Venture.

If you are trying to decide between getting a 4 Star or a Venture
without a doubt get the Venture. Bruce makes some of the nicest
kits you will ever see. And its a terrific flyer.
