Hey people how are you!?

First, of all, I would like to thank everone in California who voted for me as their governor, I really won't disappoint you.

I bought a Hangar 9 FuntanaS 3D 40 ARF and I was wondering if you could help me choose and engine for it.

I havve about 3 years of experience in the hobby and I have had my trainer(Superstar) and my second plane which was a Sig 4star.

I am leaned towards a 4 stroke, and since it is my first time with them, I would like some help because I do not know much about their brands and quality and such. Please keep 2 strokes out of the subject.

Thank you all in advance and long live California!
