Crash with ICE plane

I am at my wits end - I have an internal combustion engine plane and i cant figure out why it goes into an ossilation after the takeoff phase. I can take off normally and about 150m in, there is a ossilation of the plane that sometimes can recover from and sometimes i have to switch to manual. This last time I crashed it.

Does someone have any idea what could be the culprit with this log?
