Total: 1650.1 hours
Control System: 26.7 hours
Control system interference: 0.3 hours
While fitting the cabin top I noticed there was interference in the control system from nuts holding it together. The fix was obvious (just reverse the bolts) and I suspect when it’s all put together the elevator stops would have prevented the situation. However given such an easy fix, I just reversed the bolts.
The plans show the bolts inserted from the rear. In this configuration if you roll full left and then pull back all the way on the stick these nuts will interfere with the control column.
