I decided I would put everything together (cowl, spinner, etc.) for a few "dress up" pics.

Would this launch a 4 lb Zeph flying wing do you think? I can get it off with a 25' bungee stretched out to about 75', but I need a person to release the plane. When I try to release it myself I just can't get on the sticks quick enough and the wing goes into the ground.
I am thinking of doing a short video of how to build one. There are some sketches on the web but I did not find any complete stuff.

I think you could launch anything. The I have 30 feet of 1/4" silicon tubing and I doubled it. I only stretched it 2X and it is supposed to be able to go to 6X. I don't know what the Twister and Funjet weigh. I may try launching a Zagi with it.

I figured you could stretch the cord more or less depending on the weight of the plane.
