Title: Combat Kit ????
Post by: Clifton Gregory on February 15, 2021, 08:45:18 PM

I have 2 Dumas Diamond Combat kits I bought awhile back. Of course both kits don't have the motor mounts. Can anyone tell me what size mounts it takes. Thanks

 The plane calls for up to a .36 engine, I would use the size that Bob said. The Diamond is listed in  Combat, page one.

I remember the Dumas Diamond as a kit that was obsolete and sold at discount by AHC when I got into big (35 size) flying. 

Back in the day, it was common to use simple 1/2" x 3/8" hardwood mounts all alone.  As with Riley Woote's Voodoo, it was soon realized that the hardwood needs some help from plywood or a balsa pod.

In 1959, Fox Stunt 35's, McCoys, and such plain bearing engines were used in combat.  I think a Diamond would do better with a modern 25.
