2014 ISR Gliding events
Fred:
Hey John,
Not much :)
Main thing is to keep it simple, and above all, reliable!
I simply drill a hole as close as possible to the glider's nose. About 4mm diam. Can be anywhere, on the side, under the fuselage etc.
I then glue a plastic tube on each side of the hole. This will allow to guide the piano wire (about 2mm diameter) properly.
That gives you something like this roughly: nose <-o-----
And the piano wire, commanded by a servo. std size if you have the space. Can be glued on the side of the fuselage for exemple.
On release, the piano wire must fully release from the aperture to make sure that it will release!
Harder to explain than to actually do it! Should take you about 10 minutes to install.
I asked one of the daughter to draw a picture! (that's my excuse!) Might be way easier to understand! :oops:
Now, depending of the size of your glider, just stick Velcro underneath, and this can be used to tow your glider. The Velcro will hold when you pull, but will release if you apply down force (put the nose up, the glider will release).
Did it this way when I was flying F3I with gliders up to 4m!
Simple :D
Happy Days:
Hey John,
the easiest way to hook up a glider for towing is as Fred says with a small piece of Velcro.
How it works in flight is rather difficult to explain, but be assured it certainly does. I can vouch for that. :) So if you're going to the aerotow event, this is all you'd need to do to your glider.
I’ve taken a couple of snaps of the under side of my Phase 6. (They're not as good as Fred’s daughters drawing of a hook release system because she is very cleaver at drawing……She must get the ability from her mother) But it shows all you would need to do to tow a model up to about 4mtr wingspan.
Here they are, a Before & After shot. Couldn’t be simpler! Ignore all the other “work in progress” in the background.
I never believed such a simple thing as Velcro would work, until I saw it in operation! :D

Thanks,
I do hope to attend, like to see aerotow in action. I like Keiths method with velcro, simplistic and easy.Perhaps it requires a more skilled pilot?
John.
Alan_Perse:
I hope to make the Aerotow event.
Alan_Perse:
Any more info on the Aerotow event Fred?
