1:7.5 Scale Collimating Reflector Sight for use with headtracking FPV camera in a RC plane cockpit. Designed to fit perfectly in models with wingspan between 1400~1700mm. Useable for warbirds from 1200~2000mm wingspan. See Common RC Model Scales for your plane.
Attributes:
Parallax free - each reflector sight is meticulously calibrated by hand, keeping reticle center point aligned with the plane's nose, regardless of FPV camera movement. Reticle center dot precision is comparable to red dot sights costing several hundred dollars.
Excellent landing aid - ARMS reticle is designed to be used for precise attitude reference against the horizon, providing intuitive feel for level flight, climb and descent. As well as precise landing approach reference and flare angle reference. See landing video.
Dogfight fun - the Mark II reticle design is derived from Spitfire reflector sight in WW II. So naturally it's an excellent tool for practicing dogfights with other FPV friends. Put the bandit in the reticle for a second and it counts as a kill. Record your dogfights for bragging rights!
Self-adjusting brightness - Built-in light sensor auto adjusts reticle brightness to accommodate ambient light for FPV camera from day bright to dusk (near darkness).
Easy to install - simply drill a 10mm diameter vertical hole in the dash and slide tubular body down. Adjust sight angle by shimming tape at different spots on the tube. Alternatively, attach in front of the instrument panel with reversible adhesive. Power the sight by plugging into a spare receiver channel or servo Y-lead. See install video by RoboBiggles
