About this Plan
Sailaway. A 15 inch span chuck glider. Plan also includes a 6 in span trainer. Aeromodeller May 1959.
Quote: "For maximum fun from a minimum-of outlay, the humble chuck glider is unbeatable. Sailaway by Vern Clements.
Try a chuck glider for sheer modelling fun. Cheap to make, robust and long-lasting, they give endless hours of pleasure and are capable of high duration flights. 'Sailaway' continues upwards from the launch as if it has no resistance, soars over the top without stalling and dipping, and settles into a smooth floating glide. It will ride a thermal just like a bird; but first you have to launch it fast.
Draw it behind you at arms length, run forward three steps and throw at a 30-degree angle with all the power you can put behind it. Release the glider in a right-banking attitude; left rudder holds the nose up until the launching speed is expended. At the top of the launch your profile Sailaway hesitates, then skids into a very flat glide path without losing any precious altitude. It glides much slower than its heavier pod version brother (both variants are detailed on the plan).
All with so little expended, and with no mechanical worries such as engines, timers and dethermalisers. The thought of losing your gliders is no worry to you since there is little money or effort invested in them. A replacement can be made easily in an evening. Before this type of performance can be enjoyed you must test your glider carefully, remembering that a small adjustment goes a long way. The laminated pod version will probably balance close to the point indicated on the plans, without adding ballast. The profile version will require some lead in the nose.
Test glide, using a slight left warp in the upper half of the rudder for turn. If necessary, a V-shaped wedge approximately in. long by in. at the thickest point may be pushed between the trailing edge of the tailplane and the boom, taking out enough incidence to prevent looping on a hard throw. Leave just enough angular difference to pull the glider out of a dive in the event of a bad launch..."

That happens sometimes. You can help us fix it.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
