Help ?

Just purchased a dg1000 from HL has anyone put a tow hook on, and if so approx. where did you place it? I'm looking to highstart launch mine, not many hills!

If the DG1000 I am thinking of from HL is the one in the picture then you will need to set it up differently since there is no retract in the plane. Search for the thread on the DG1000 in this forum and you will see some of the weaknesses in the plane. Its fine for sloping or conversion to "E" power but the wing rod may be a weak point when using a high start.
As far as location of the hook, I would suggest 1/4" in front of the cg and watch the wing flex as she's going up. If the wing is flexing too much the stock carbon wing joiner will snap (yeah I snapped a couple) and even a steel joiner will bend(been there done that too). While I did not use a high start I did winch it once which required a lot of pumping on the pedal to keep from folding the wing.

Let us know how you make out,

I should have looked myself, the link is right here

Thx guys for the help, I've read all 19 pages on the build blog saw 1 photo of hook but no hints as to were it was put. I will keep posted on the launch.

Tow hook location

I made a dual tow hook setup on my first DG1000. Each tow hook was placed about 5 mm behind LE and 15 mm or so below the wing. This setup was chosen to ease the load on the wing, at the cost of launch height. This is a scale sailplane, and NOT a competiotion thermal sailplane. I can't provide you with accurate measurements because I no longer have that fuse. With the carbon rod, yes, launches can be quite exciting, with the wing flexing upwards. Dont even think about pulling up elevator. Then, you might end up trying to control a lawn dart.

Hi,

I would not recommend fitting a Tow Hook anywhere near a retract the structure will not be strong enough.

For a Scale ship use the bridle method it's by far the best and safest.

With the bridle system the plane will not wonder on launch as a single tow hook will as it will pivot on the hook

I should have said "bridle set up", instead of "dual tow hook setup" in my previous post. If you look through the other thread, I have loaded few images of how I did it with my DG1000.
