Stunters often had somewhat long nose moments.

They often had somewhat large horizontal tail areas that were on somewhat shortened tail moments. Shortening was required in order to do the "5 foot radius" turns. Then the larger area was needed to make up for bringing the area closer.

The nose is easy to deal with. It's not obvious when you shorten 'em up a bit. But moving the tail back can be very obvious.

When I moved into R/C, I was drawing my own CL stunters at the time. My big drawing board was setup and ready to go so I drew a couple of RCs right off. Recomputing the suckers was a heluva chore. The board is gathering dust now, but thankfully, there is an online application that does the figuring in a heartbeat. And varying the numbers is realtime... like NOW... instantly done. Go to http://www.geistware.com/rcmodeling/cg_super_calc.htm if you feel like crunching some numbers.

Most of the CL stunt engines were very light, which is why them puppies sported the noses they did, especially the ones developed for Fox .35s.
