Any work around for the porpoise effect?

Try this great little free beta universal autopilot :http://fsxpilot.com…It might help

@Cozz5505 Thanks, might take a look if MSFS can’t get the default AP reliable and with all the standard features (VNAV, etc.)

You are welcome, it works great for general fun/sightseeing and making videos etc, but kinda takes a bit of fun out from controlling the aircraft from the cockpit.

I did have some success preventing the “dolphin” in the Longitude messing with the weather. I set the weather to preset clear, did start up, took off, and THEN turned on live weather. Just a couple seconds of the “dolphin” on the switch but other then that I was able to get up to FL30. Interesting thing I never had a different wind reading besides 3 when AP worked. But then messing with the flight plan in FMC while climbing it crashed. So I give up, this bird is staying in the hanger - Big INOP sticker on it.
