[QUOTE="Virtual1, post: 90338, member: 4084"] I suspect the pin-up procedure on the spark is a VERY carefully monitored process, to verify all four of the props are: - present - firmly locked down - balanced - identical in drag All of this can be accomplished by monitoring the amount of current the motors draw when they are spun up AND slowed down several times during startup. That's where you get the "vmmm-vmmm... vmmmmmmmmMMMMMM" startup sound from. The spark is throttling and braking the props several times to compare current draws on all four. The BRAKING is to make sure the props are LOCKED down and not just pressed down vertically on the shafts. So my guess is one of your four pops wasn't locked down. [/QUOTE]
