E20 Free Flight Timer - Dead Stop with Prop Brake Test

Peterborough FET Timer for Open E20 Free Flight - 8 Seconds for Coreless Motors on direct drive (Tested with Chaoli 615 Tiny Whoop motor.) This timer version uses some extra FET's and circuitry to stop the motor with no 'decay' and applies an electronic prop brake to prevent free-wheeling in the glide. (A problem with some coreless motors.)
