F1N HLG

Introduction

F1N indoor hand launched glider (HLG) is a very popular class for indoor flying. Both javelin launch and discus launch are allowed, but catapult launch is not.

Follow this link to watch a video of an Indoor HLG (cat.2) flight.

Here is the winner for F1N at the IIF 2009, Jurgen Maassen (best flight 34 s). The model looks like the Indoor Low Ceiling Chuckglider (Jrgen Korsgaard, 1986, free plan).

 

Here you can see a launch in Kent, USA:

Plans

A good start is the Indoor Low Ceiling Chuckglider by Jrgen Korsgaard, download the free plan.

Another good plan and very well documented is the SuperSweep article and plan by Ron Wittman.

Other plans and articles can be found at AMA glider. Some of the plans on this site are for catapult launched gliders, but these can easily be used as hand launched gliders.
