With all sincerity Rick, the Ultra Sport will be a major step DOWN from the Aeromaster. I think you will be disappointed with a US after building and flying the Aeromaster.

BTW- The Ultra Sport is a very easy build and flies well, but I prefer the original Bridi airplanes. The Dirty Birdy or the XLT is far superior IMO... You should check them out: [link]http://www.bridiairplanes.com[/link]


Regarding servo install-

Sheeting between the rib bays are okay, but I would trim a stick of hardwood to match the contour of the two ribs. Then I would recess it to allow for ply sheeting between the ribs. I'd do this to mount the servo on it's side, on the ply sheet between the ribs so only the servo arm would show out the bottom. (Hopefully not too confusing. I can show you an examply if you wish...)
