Default Piggyback......

How many people have tried towing sailplanes aloft by using winches put on other planes wings? I have tried it, with poor luck on both sides. Glider and "mule"(carrier). The mule was the Hangar 9 Xtra Easy. Stock engine and winch. Surprised me when it took off with a Hobbyshack Ridge Runt. The release failed and had to land with plane still there. When it did work, glider did not haver enough airspeed and fell like a rock. Tried the same winch (slightly modified) on an Avistar. Worked better, except that the winch feel apart and glider slid forward, being munched by prop. Haven't tried since. I take a high-start anyday.

I've been towed a few times by a Sig Senior Kadet with wing sailplane harness. (I forget the brand name, but it was the type that looks like the framework of a rectangular box, with two releasable straps securing the sailplane wing)

The only problems we had was the mule had to be flown at a reduced speed. You want just enough speed to gain altitude, otherwise the sailplane can shift in the cradle. The mule needs to turn gently -- very gently, otherwise the sailplane wings will dip while on the cradle. This is especially true when towing large wings. ( 99 + inches) I found it best to turn using only rudder trim
for control until release of the sailplane.

I usually fly with power-pod, but an occasional tow is a great change of pace.

Here's one easy way to do it. I'd be interested to see others.

We do it both ways. The mother ship is a SR falcon with a rack on top. It works well but flys with rudder only when it has a glider on. I like both methods. The mother will not carry my Kamiak. Its too big. Gotta winch that one. Building new winch though. My old one is older than I am, and I am not that young. both work well though.
