Charlie Fox replied to Hugues's discussion Quadcopter X8 configuration in ArduCopter User Group
"I've had great results in various coax set ups using the same diameter but different pitch props, eg, 3.8 & 4.5 or 4.7.

It probably won't be as noticeable on an octocopter but a coax hex with different diameter would probably not fly very well due…"

Charlie Fox replied to Cristian Rougier's discussion Motor spin slow than others in ArduCopter User Group
"When I bench test my octocopter I have a similar issue.

Many people assume flying is easy, based on ardrone or similar experiences.…"

So I have 2.9.1 on an APM2.5+ and have been doing some bench testing without props.A striking anomaly occurs at low rpm/throttle, it may also happen at high rpm but isn't as clear.If I put the stick up just enough to start all the motors spinning.…

Well this one is really doing my head in.Have been trying to setup the gimbal, but which ever axis is connected to RC11 just twitches randomly and aggressively all over the place.Also as an aside, are RC1-8 the same as outputs 1-8? trying to work…
