can anyone help me with the c.g on a early short boomed bobcat and also control movements thanks regards jonathan

There should be two small holes at the bottom of the booms for CG. Get about an inch of up and down on the elev with 20% expo. Alireons are very strong, so get .75, .5 and .25 of an inch for tripple rates. Rudder one inch...

You don't need no stinkin' expo....
