whats the best size motor for a Acrobatic Extra 330 90 - 63"
I am just trying to fly gas powered planes Ive had a few electrics but i got a good deal on a Acrobatic Extra 330 90 - 63" and I was hoping someone could give me some direction

OK, we know what an Extra 330 is, we also know that it is aerobatic (the term used in some countries is acrobatic). I wonder what "90" stands for? Maybe size - 0.90cu.in. or 15cc?
Alright, now seriously - 63" WS for an Extra is usually a 60-size plane. As an Extra will benefit from some extra power, and a 90 engine is usually a bored-out 60 (same dimensions on the outside, same mounting pattern), then a 90 sounds like a good size.

By "Acrobatic Extra 330 90" do you mean to say that you have an Acrobatic Extra 330 90 MARKETED (offered) by Nitro Models? Are the pictures I post of your model? If so, the listed specifications by Nitro Models are:
Wing span: 63 in / 1600mm
Wing area: 713sq in /46 sq dm
Flying weight: 6.6 lb / 3000g
Fuselage length: 60 in / 1520mm
Engine Required: 4c 0.91 cu in
Radio Required: 4channels,5 servos
If this is your model, are you asking for recommendations/opinions of what the best manufacturer of a 0.91 4-cycle engine would be best for this model?

A friend at the field has that EXACT model, in another one of their color schemes. He's running a Saito 1.00 and a 15x6 prop. He's very happy with the setup.
Me............ I have an Edge 540 (similar to extra) with a 68 inch wing, with about the same weight, and I run a 1.20ax.

Oh and btw............. BRACE THAT MOTOR MOUNT ...............or it WILL come apart!!!!! Use triangle stock in all the corners for support. I saw it first hand. Only took three flights to cause almost irreparible damage!
