The fact that there are higher performing hand launch gliders is not a NEW piece of information. The key here is that for very little money and time, the Bug can be built and flown. Like you said, 'The Bug is a great fun machine'!!! Most of the modifications you read about in the archives, are meant to enhance the side-arm launch and performance capabilities without a major increase in cost or complexity of the design. Extending the wing span to 34 inches does increase the soaring performance and is not that complicated. The simple extension of the spar to the tip and the addition of an x-tail, makes this glider a decent side-arm launcher. This is a simple yet elegant design. It forces you to learn minimum loss flying. This means that you fly with minimum control inputs and yet coordinated to the airstream. Please don't make this a discussion about what other gliders would be a better idea to build. This group is for those who have built, or want to build, a Bug.
