DualSided 0–50° Angle Range for ProLevel Setup This RC fixedwing inclinometer and aileron angle gauge provides exact readings from either side across a wide 0–50° span. It covers everything from gentle sport throws to aerobatic deflection. A legible scale and smooth pointer movement help reduce reading mistakes, so you can align deflection more precisely and keep your model tracking straight through demanding maneuvers. SpongeLined Grip Protects Control Flaps The inner jaws feature soft sponge pads that cushion ailerons and other control flaps during measurement. This reduces the risk of scratches or dents while clamped and gives you a steady hold without marking paint or film coverings. Suitable for foam, balsa, and composite wings and tailplanes used on RC fixedwing models. CNCMachined Aluminum Alloy + Plastic, Compact Size Constructed from CNCmachined aluminum alloy paired with quality plastic, this gauge feels solid yet remains lightweight and easy to handle. Its compact footprint of 20 × 16 × 2.5 mm slips into any field box, and the sleek black finish looks neat on a bench or flight line, ready for a quick check whenever you need it. Fast, Consistent Aileron Matching at the Bench or Field Clip onto the trailing edge, center your radio, set throws, and read degrees at a glance on either wing. The dualside scale helps you match up and down deflection more consistently, enabling precise finetuning of endpoints or subtrim and smoother, more predictable rolls for your fixedwing aircraft. Use scenarios During initial setup of a fixedwing model, clamp the gauge to the trailing edge to verify and match left and right aileron throws, ensuring symmetric deflection for balanced handling. Between flights or after component changes, perform a fast field check to confirm deflection remains aligned, then adjust endpoints or subtrim as needed for reliable, repeatable control response. When working with foam, balsa, or composite wings and tailplanes, use the spongelined jaws to avoid surface damage while achieving accurate, repeatable measurements.
