      Hi Marc and all, I'm hoping that I might be able to help at least a few of you guys who are just starting to use a bungee, by describing a few of the techniques that can be employed to make "marginal" power bungee systems work better in practice Firstly, wind, any wind, seriously improves the power available to be used on any launch. If you start using a bungee on a dead calm day you'll see this immediately Secondly, you'll find that, the more ooomph you can get into the first few feet of the launch, the fewer problems will appear as you start to really get into the climb Thirdly, the glider should be launched at roughly 45 degrees nose up, no more, and certainly no less, and you MUST launch squarely into wind ALWAYS.....every time Don't stand , ready to launch the end of the line, any more time than you absolutely have to.......holding the bungee at full stretch really kills it over time You can improve any launch by weaving on the line, but only after you are settled into the launch, at about a quarter of the way up, weaving stretches the line and improves the pull, especially if you feed some up elevator at the same time, but doesn't increase the total energy of the pull........that's simple Physics for you.......this is also known as "kiting" Gauging the moment of release at the top of the launch is important too, try to get off just before the model does it for you...... Towhook position is also critical and an ordinary cup hook is often better than the releasable type because it can be "tuned" by moving it forward or back depending on the conditions.....just drill holes in front and behind the starting position and move the cup hook either way as necessary Then there's CG position, the hook position must enable the glider to "cock" on the launch settling the glider's angle of climb to maximum effect I won't go into caring for the bungee rubber or repairing line breaks just here but, if anyone is in any doubt as to look after their bungee rubber, please post here and I'll try to answer what you want to know.....oh, and hand winches and power winches either...... they're quite complicated to get working at 100%....... Smooth, high launches and long flights chaps Regards Pete BARCS1702

      Hi, I think we may have met at wormwood Scrubs last weekend.. I was flying my supra off the high start. (My favourite way to fly bar slope soaring) I got my 2 mtr class bungee from Seta tek in Germany as I have built his models and he sends a complete ready to use high start.  I purchased my 3mtr and above high start from the states, super nice quality components and you can specify exactly your requirements. see links below. http://www.seta-tech.de/ https://www.aerofoam.com/complete-3m-1.html best, Leo.
