Riveting .... splice and doublers on LE skin. Needed to hold in proper shape for the holes to line up.

Finished riveting, weighs 3.42 lb, little heavier than I wanted, but very stiff. Next the loading to Limit....Stay tuned.

Limit load test of elevator. Per "Faa Basic Glider Criteria" 12 #/sq ft. = 92 Lb. Uniform distribution span wise. The weights sit at the centroid of the ribs. This includes the gust loads. Elevator is mounted as it would be in the aircraft, from the hinges and control horn. Result...no deformation, usable part.

Got my airspeed indicator today...Hall Wind Meter 0-80 MPH ....tested it with the car and it works pretty good.

Figured I would use it as a sure thing for initial flights.....its hard to know if a standard indicator is good because of negative or poor static pressure issues. I would be interested to know what anyone else is using considering the stall is supposed to be 19 mph.

Quick sketch of engine and revised pod structure. Very preliminary drawing. That is a really small engine.
