Hi Doug,
If no one else has an actual GS (J Roberts) kit, I may be able to help.
Brodak has several J Roberts Series carrier kits. The Skyraider & the Bearcat. If you look deep enough, they also had an F4U Corsair.
NO! NOT the "Coming Soon" Kit CLP-29!!! This is a stunt plane! PG#43 Cat#15A
This is Kit JR-1. The full size plans are on P#62. BP-1497-CLPJR1 $10.00
This is a profile carrier plane, NOT a stunt plane.
Eng: 19-49 Length: 29" WS: 40" WA: 315 sq"
I have this kit and would be glad to trace whatever you need if no one has your actual kit.
"Tight Lines!"
Wes
