Rules Survey

[Wladimir Kummer de Paula]

For me Balsa, Ply and FOAM are the best composite materials....Safe and 
easy to work on...

You can really achieve the weight limit with a wood plane. Careful 
engineering and building are the only skills necessary. You can 
experiment with lighter (and cheaper) paints as the latex ones, also the 
safest. They are not glow proof but will tolerate gasoline fuels. I´m 
experimenting with top coats to make it impervious to glow.

Use epoxi only where it is really necessary. PVA glue is so much lighter 
and with a good joint it can become almost as strong.

I do think rule change to acomodate a increase weight is necessary so we 
can use less expensiv and more powerful gasoline engines and could use 
eletrics withouth sacrificing structural integrity.
