ASP FS400 magnet ring and sensor bracket

Magnet ring and CDI sensor bracket for doing a electronic ignition conversion (glow or gasoline) of ASP FS400-AR radial engine.

Magnet ring
Designed for 3x1.5mm magnet, and a 2mm bolt and nut to clamp it in place (or use CA). There's a notch, once timing is set and confirmed, make a scratch in the prop hub adapter to make re-timing easier if it shifts.

Sensor bracket
Requires a 8x10 mm (aluminum?) stud, drilled to accept a longer crankcase cover bolt (4x25mm I think?). This is epoxied into the bracket, flush with the bottom, so that the bolt is pushing the crankcase cover closed via the stud, without stressing the plastic bracket.
Cut the mounting arms off the sensor and align the depth with the magnet ring, then hot-glue it into the bracket with the flat side facing the magnets.
