[/size]Regarding the braking, there are currently a few interesting things, but they're not enabled by default. Ziss_dm did this in wii-esc, which I borrowed: You can set "COMP_PWM" to 1 on bs-type boards (or boards with ir2101s chips, generally OK). Check with an Ammeter first that there are no dead-time issues with the FETs being driven this way, but if it works, you can get a much more linear throttle response, active braking/regen during flight, and actually improved efficiency due to reduced conduction through the body diode of the FETs. If you try this on a P/N board, it will likely blow up. Most boards I tried draw very high current at any speed if there is a dead-time issue. F-30A, F-60A, and some ir2101s boards I tried all seemed OK; TowerPro with BL8003 was not happy until I added 1µs between switches. wii-esc's "comp_pwm" directory contains wii-esc builds with this enabled as well, and he is using delta-sigma modulation instead of 18kHz PWM.[/color]
