I'm new to 3D, but have a gained an interest recently, as I have exhausted scale building in past 8 years with over 50 builds, many scratch builds. 3D is something new and interesting to enter into, as well as having new subjects to build and fly. I recently built a 30" Herr Pitts as my first 3D plane, which is flying, and still needs a bit of tweaking. I'd love to build a sport monoplane soon, and have been looking at the Dan Rihn One Design and RV4 and RV6 models.
