This is the method used for the first couple of takeoffs, until we got the plane correctly trimmed. It is a very easy process: full power is applied, which extends and activates the EDF unit, and the glider is launched as horizontal as possible. On a windy day, the relative airspeed makes it climb very fast the first few meters and then it stabilizes and enter a normal ascent rate. On a calm day, it will be important to keep the plane horizontal until it gains enough speed to avoid any premature stall.
Very much like its scale counterpart, the ST Model Salto is capable of taking off on its own, as long as the friction against the runway is low enough. That means basically that it won’t take off from grass, but will have no problem to take off on a concrete runway. As long as the plane is on the ground, there is limited rudder control, and the Salto may easily be pushed around by the wind. The rudder does not have enough authority for a crosswind take off, but if the nose is directed
|straight at the wind, the Salto will have no problem taking off on its own. This is a very nice feature, and not very frequent for a plane of that size (although ST Model has an unusually large offering of self-launching gliders in the 2-meter-wingspan range.)
The stall only appears a very low speed but it is brutal, with a tendency to roll over on one wing. The plane recovers easily in less than 30 feet, thanks to a very light weight airframe. This is to be watched on landing, as it better to come with some speed, even if the plane ends up rolling over a long distance.
