Fabricated the aileron pushrods connecting the aileron torque tube to the bellcranks and test installed everything. The ailerons are working very smoothly but there is some friction on the elevator connection that needs diagnosing and rectifying. The big job today was to replace the contol column mount tube which I'd made from 5/8" square tube rather than the 3/4" called for. This mean't there was too much play in the control column so couldn't be left.
