Can not take off in the Optica

Since I’m asking about aircraft issues, here’s another. I have the “Optica”, and have never been able to use it. When trying to take off, it won’t, and eventually crashes on the runway; if I start in the air, it immediately becomes uncontrollable, spinning into fiery death. Anybody? Thanks, Mike

Do you have the Orbx or Got Friends version ?
One thing I am thinking of to check is to make sure your flight model is set to “Modern”.
