Thank you for your assistance!

However, previous contests have ALLhad rolling take-offs, this being the first year to launch by hand. I was looking more for a range of wing loadings that have worked for RC aircraft about this size (i.e MQ-11 Raven, 6 ft span, 2-5 lb W_empty, 6 ft length (rough estimates)). All we need is a range of values to start looking at.

Thanks again!
