What is the weight spec for the dacron that was used on the wing tips on the
earlier Lazairs? Is the dacron sold by "Spruce" company zero porosity, or
does it matter? The lady that takes your calls at the company doesn't
know what zero porosity is.
Thanks,
Russell

Russell,

I used Medium weight Poly-Fiber from Aricraft Spruce. It does require you to "seal" the fabric and apply a UV coat prior to painting, but yeilds excellent
results.

A strobe light?

Very cool.

I've been working on that idea myself, and think its important safety to have, since we are flying low and slow.

What are you using for your system?

Ray,

I had a guy design this for my plane. He builds strobes for the RC industry. The only regret I have is that I learned about 12 volt Gel Cell batteries too late and so I'm using 4 D-Cell batteries to power the strobes that I have on both tips. The entire set-up weighs literally ounces, the batteries weigh several times what every thing else for the strobes weigh.

Pics to follow...

Thsi is the battery pack I built that sits directly on the boom tube on the CG. It has a small switch on each side to turn on each tip strobe.

Thsi is where it is mounted. You can see the plugs that I use to plug them into the wing.
