I know that, for level flight, the CG has to be in the same place as the glider's overall center of lift (both wing lift + tail lift). Not quite. You want your CG forward of the NP of the aircraft for static longitudinal stability - meaning that you will have a nose down stabilizing moment when perturbed during flight. Typical acceptable margins for ...

When you pitch the nose down to gain speed, it feels as though you are pitching down a long way This is because the change of the cockpit angle towards the horizon is the sum of both the angle of attack and the glide path angle change. This means that at low speed your speed changes should move the target point up when you go faster (the point is only ...

Pitch attitude in itself isn't the big factor, other than as a speed control tool (in gliders). It's mostly about whether or not the position of the spot on the ground you're approaching changes (moves up or down in your view) at whatever pitch attitude you're holding, when that pitch attitude is being held constant. This is key for judging glide path on ...

Others have already answered your question (the answer is attitude), but I would just like to talk about "CMD" This is an autopilot mode, it has nothing to do with attitude (well I guess it kind of does, read on!). There are two modes: CMD and CWS. CMD stands for "Command" and CWS stands for "Control Wheel Steering". I will use ...

Joe Ayoob's world record throw of the John Collins designed paper airplane is worth watching over and over again. Every time I throw the glider with my hand ... This caused me to split my free flight hobby into throwing gliders and launching from a hill. A thrown glider experiences a wide range of speeds in flight, therefor it cannot be set with a staticly ...
