Keep the Skinny Birds Flying Safely
I have a 1940 CP50 that I am restoring from the ground up. I built new ailerons and transferred the lead weight from the old aileron to the leading edge spar of the new aileron. While in Osh Kosh I saw a LP65 with headknockers for balance weights. My CP50 was not equipped with headknockers. I searched for AD's but could not find any for the CP50. Does anyone know if the headknockers was an STC or some other add-on? My ailerons are quite heavy at the trailing edge. I have always been told that ailerons must be balanced to prevent flutter. Comments please?
