Mark's 5 seconds is pretty close. My belly board takes about 6 seconds to extend / retract from maximum deflection of 90 degrees. https://www.youtube.com/watch?v=cgdgxVgPNAk You can time the retract at the end of the video. I'm able to go around with the board extended but climb rate and acceleration are limited, even with the 0-200 at full throttle. As for retracting on go around, the last couple of seconds are a non issue as the effects of the board decrease as the seconds count down. If the last two or three seconds of retract makes a difference in life or death you've made too many mistakes leading to that point to matter, IMHO................ Larry Flesner
