From everything I have read, this was supposed to be a very difficult task. Twelve year old Will Clark (nephew) had smaller hands and was able to make the attachment in only a matter of minutes.
Trim tab motor and arm were also quick and easy. We had about 1/2 inch clearance between arm and rudder when trim motor was fully extended.
HS attached.
Trim motor attached. Functioned properly when attached to 12 volt drill battery
Everybody adds this shot to their web page...cool looking
