Altitude hold issue

[vegasjon 39]

Hello all!

 

Just picked up the 550 a day ago, and I am having an issue holding a steady altitude with the default AP- The aircraft will porpoise +- 500 FPM while trying to hold a set altitude...is this a known issue?

I am having ctds just changing interior views which is a pita. No issues with the ap YET but on the Phenom I was having all kinds of problems holding altitude. May not be your problem but mine was I had the TRIM set to a TM Warthog throttle wheel. During trouble shooting I removed it and all is well. I now use a hat switch on the stick. I no longer ask WHY it works but just that it solved it. Maybe try to remove your elevator + and - and see what happens.
