By pinning the parts directly to the building board, you can ensure that everything stays aligned and in place while the glue dries. This is crucial for maintaining the accuracy of your build, as even a slight misalignment can affect the airplane’s flight characteristics.

A building board, like the Great Planes Pro Building Board, provides a flat, stable surface to work on and is designed to withstand repeated use of pins without warping or becoming damaged. Some builders prefer to use a cork or foamboard surface, which can be easily replaced when it becomes worn.

During the construction process, T-pins hold everything in place, allowing you to focus on aligning parts correctly and ensuring that glue joints are secure. For example, when assembling a wing, you might pin the ribs and spars in place over the plans, then check the alignment before applying glue. This prevents any movement during the drying process, ensuring a straight and true wing.

15. Servo Tester

A servo tester, such as the Hitec Servo Tester, is a valuable tool for anyone building or maintaining RC airplanes. This device allows you to test servos independently of the receiver, ensuring that they are functioning correctly before installation.

Servos are critical components in an RC airplane, controlling the movement of the control surfaces like ailerons, elevators, and rudders. Ensuring that your servos are working correctly is essential for the safe operation of your model. A servo tester lets you check the centering, endpoint, and smoothness of the servo’s movement, helping you identify any issues before they cause problems in flight.

For instance, before installing a servo in the wing to control the ailerons, you can use a servo tester to check that it centers accurately and moves smoothly across its range. This allows you to make any necessary adjustments or replacements before the servo is installed in a location that might be difficult to access later.

Servo testers are also useful during maintenance and troubleshooting. If your airplane is not responding correctly to control inputs, a servo tester can help you determine if the problem lies with the servo or the radio system. By isolating the servo and testing it independently, you can diagnose issues more quickly and effectively.
