 Hey guys,

We have a good plane built that did 2:00 in our regional site of 25ft for
Division C Wright Stuff. However, we are gonna be flying at a 80ft gym in
states, and I want to get an idea of what is the general prop/rubber
combination for such high sites. I was thinking low pitch and thin rubber,
but what would be a good point to start? 1.2 P/D and 1/16 rubber? Please
give me the angle for the P/D ratio too, because I confuse the ratios and
angles a lot. Any help would be appreciated.

We are also practice flying at a 20ft gym at our school, should we use
partial motors to try to get it to climb up high?
