Equations for actual lift of a wing and rotational moment. Pitching moment of a semi-symmetrical wing is negative and constant over the usable angle of attack range. Aircraft moments are defined and discussed. Drag contributes to the moment if it is above or below the CG. The wing lift & horiz. stab produce moments multiplied by the moment arm (CG-AC of each) All 3 sources must balance for the aircraft to be stable in pitch A specific elevator trim balances aircraft pitching moment at one airspeed. A more rearward CG causes the model to be sensitive to trim.

Seattle Area Soaring Society lost several members because newcomers did not obey frequency control system. Foamy models are making it of no consequence to have a crash. Pre-built models reduce the sense of ownership. Members don't ask for help and don't know safety rules/issues. Flying a combat model minimizes safety considerations, we learned over decades. Solution: members ID newcomers and make sure they know the rules including AMA membership. Persons who violate rules are approached by a number of members and one member of the safety committee. Actions have improved field safety and more newcomers are joining the club.

Gred recounts how he lost a Wizard Compact molded sailplane due to battery problems. He was comparing a new version with a cruciform tail to a V-tail version. In a rush to get to the slope a new, untested battery was put into the Wizard. After a few minutes it went flat causing the model to dive into Lake Michigan at 100 mph. The moral of the story is to test every battery you are going to use in a nice model a couple times a year.

A digital servo driver is a tool that allows one to operate a servo w/o a transmitter and receiver. Set maximum servo throws. Super Digi-Set 2010 and ServoXciter also report pulse ratio from the receiver and confirm the servo will work as planned. You can save a servo or avoid damage to the model due to a servo moving in the wrong direction and being stalled. The sweep function is very useful for checking for damage on crashed models. It can also be used to check speed control hookups for direction of rotation.

A study of sheer load in the spar of a wood wing is discussed. A truss structure is very effective but has a high part count. Sheer webs are practical alternative. Vertical shear web grain, if it is stronger, may be true due to its adhesive bond to the spar cap. If the rib is split it should be securely glued to the sheer web or the wing will be weak. Avoid holes in the sheer web. Reinforce any required holes.
