Sharp edge KF's or rounded whats your take? preference


Well the sharp edge is to create a vacuum and disturb the airflow creating stability and lift to an extent. Smooth back edge then you are using the kf just for wing strength.

The main problem with a blunt flat LE is that it creates a sharp rapid change in airflow characteristic as the angle of attack alters .... this can lead to bad habits at low speed ... 
This is true regardless of KF or not.

There is another way to create a LE that can take a knock or so ..... run a smoothed bead of Hot Glue along ...

I have always used bamboo skewers and reinforced tape and I have never had any issues with that.

If you saok the bamboo skewers - they become bendable such that when really soaked - even make hoops.

Thinking of that ... what do they call that wood strip used to make baskets etc. - dunno bout you guys but in Junior School we all made trays etc. for home.
