About this Plan

Lamb Climber. 1941 National Open Stick Champion.

Quote: "How to Construct the Winner of the 1941 Nationals Open Division Event Which Flew for 1002 Seconds on Three Official Flights By ED LAMB

THE Climber was completed at 4 o'clock the morning of the 1941 Nationals at Chicago; however, it is far from being a ship that was thrown together in a hurry. About a month before the Nationals plans were drawn up for the model and before my brother and I arrived in Chicago, the wing, tail section and propeller were completed the fuselage was built the two nights previuos to the contest.

We believe that this model's outstanding feature is its tremendous climbing ability. At the Nationals it had one flight of over seven minutes and another of over eight minutes, before going out of sight of the timer's stand. On both of these flights it landed about ten miles from the field. The total for the three official flights was 1002 seconds. In evening flying, the plane has been averaging over three minutes a flight.

Construction. The fuselage is constructed of 1/8in hard balsa; the easiest method is to con- struct the two side sections first. Cut the longeron strips to right length and pin them on a board to the right shape, then cement in the crossections as shown on the plans. After both sides are completed arnd identical, cement in the top and bottom erosscetions, starting at the middle and working toward both ends. After all the crossections for top and bottom have been inserted, glue in the braces and 1/8in sheets as shown. The tail section is detachable and should be constructed separately.

The wing has an area of 200 square inches and is built in the usual manner. The three center sections are made in one piece and the two wing tips made separately. After the center section ribs have been cut and sanded to the same size, place them in position using the leading edge..."

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
