Finished reinforcing the forward ailerton torque tube supports today. After that I mounted the right aileron bellcrank, with no apparent difficulty. But when I began to do the same on the left side I ran into trouble. Using the measurements in the manual left the bellcrank about an inch low, relative to where the attached tube needs to exit the fuselage. But if I raise it up, it appears the the cross-over tube may be too high. I'll have to think about this.
