The latest video in our motor minute series comes from team pilot Shane Denherder. Shane goes over the basics of speed bar use and how to properly hook up the system on a Parajet Volution. Many pilots have never tried speed bar, those guys are really missing out. Speed bar is responsible for adding an overall higher top speed which can be great if caught in a stiff head wind or if you need to make it back to the LZ before it gets dark.
On many free flight gliders, speedbar is the only way to accelerate the glider unlike motor wings that have a trimmer system as well. When it comes to motoring wings, generally trimmers and speed bar account for an equal increase in speed such as 5/5 mph. Considering we fly some of the slowest forms of aviation, these are pretty big increases! Gliders like the Gin Mirage and Paramania GTR can fly at speeds up to and over 40mph (depending on wing loading) with speed bar at full fast!
On non reflex gliders, speed bar can lead to an easier collapse as it’s bringing down the leading edge making in more prone to tucking. Reflex gliders do this as well but they load the glider so that all of the weight is on the front towards the leading edge. This creates much higher wing loading and increases stability.
If you have any questions about how to properly hook up and use your gliders speed system, please give us a call or email!
The speed system should only be used by pilots that have the training to do so. Video instruction is no substitute for proper teaching of the speed bar system. Be sure you are experienced enough before going out and trying this on your own!
