Beginning to get this one dialed in.
CP-1 in moderate lift (5 min 43 sec)

Well, I have been bitten by the PSS bug and am going to throw my hat in the ring and try to design a PSS ship that will fly at my local coast cliffs, which is modest lift most days of the year. This will cut out the typical PSS ships that you see on RCG with their wing loadings of 25 oz/sf. and up.

The trade off between the desired high speed and the ability to float in light lift will make it less fun than the lead sleds that race around at great slope sites. My little 32” span CP-1 at 17 oz./sf. and is quite the pig. It cannot even do a loop in modest lift.

If I go with 60” span, low AR, and a 11oz/sf wing loading, I could fly all year round and simply load up with ballast when needed. But that wing loading would be hard to hit with a fiberglass scale fuse and heavy skins on a foam wing. I am thinking of a Mig 3, so it is quite the chunky wing. With my normal construction techiques, it would probably be about 20oz/sf.

Wondering just how hard I need to work to make it flyable and fun for my local site.
