Tiger Shark (oz302)
About this Plan
Stanzel Tiger Shark. 1939, G-line flying speed plane. The first control line model kit.
Plan includes detailed instructions.
Quote: "The G-Line Control. Fully protected by US Patent. Flying Instructions.
G LINE FLYING is a new control development permitting high speed Gas Powered Racing Models to be successfully flown under full control. This new control system, worked out by many months of experimental work, is simplicity itself in construction and operation.
Considering that the ship to be flown is fully ecuipped with a G-Line Control Arm, the only additional eouieaent required is a control pole and G-Line. The control Pole should be about 9 ft long, preferably of rigid construction. A good bamboo fishing pole or casting rod is satisfactory. The G-Line should be a good quality silk or linen line of from 18 to 45 lb test, depending upon the power to be used in the plane. If desirable, No.2 or No.3 Music Wire may be used instead. The length of the line depends upon severel conditions, such as; speed of the ship, velocity of the wind, experience with G-Line flying, etc. That is, the faster the ship the better the control, conseouently, a longer G-Line may be used. On the other hand, if a wind is blowing, the control is less effective on the windward side and a shorter line is advisable. The longer the line, the less effective is the control. Considering these factors, the average length of the G-Line should be from 35 to 50 feet.
Special care should be taken that all fittings and connections on this control system are carefully and seourely fastened before attempting to fly the ship. The G-Line may be tied directly to the tip of the control pole, but it is advisable to fit the tip of the pole with a regulation casting rod tip. The line is then passed through the guide ring of the tip, then down the pole to a secure place of at-tachment. In this manner, there is no danger of the control line fouling about the tip of the pole.
It is advisable to pick a quiet day for the first attempt to fly the ship. Windy weather may complicate matters for the beginner. Further, beginners should use only a short G--Line, say approximately 35 ft long. The rudder should be set to counteract the circle in which the ship will fly. Move the trailing edge of the rudder about 3/8 to 1/2 in to the left, looking down at the ship from the tail end. The model, when fully loaded with batteries and fuel, should balance at a point 1 in to the rear of the leading edge of the wing. It is also advisable to set the elevators so that the model will run along the ground with-out taking off on the first test run..."

* 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.
