Suggested Parts List


The Grumman X-29 has always been a personal favorite of mine and has long been on my must-do list, and I finally got around to doing it. This model is sized similar to my other park jets and uses all the same construction methods. It is based on a scale outline of the X-29, but I took my usual scale liberties to make for a better-flying RC model—I increased the vertical tail area about 10% and also scaled the wing and canard up about 15% relative to the fuselage (since the real X-29 has a rather small wing). These changes paid off, since this model is smooth and solid in the air and can truly be called a park-capable flyer.
