Flaps matched. Wings joined with spars, first wing completed with my desired flap angles. Second wing matched to first. I don’t measure deflection preferring to eye standing on the centre line.
Full flap has pushrods inline with servo horn at full flap to reduce load.
As always with my builds the PB, Rx’s, batteries, switch etc are all for the model-so by the time of the first flight there will be 50+ cycles through the system
