This is the plane we are talking about correct?

They are saying that it comes in at 17oz. The park 480 would be big time overkill. The Park 370 1360kv would be borderline, but might be on the low side in terms of total watts/power, it may be worth a try since you already have it though. It should at least give you some borderline mild 3D, but not the unlimited performance.

Something with similar specs. to the Park 400 or Park 450 would be more along the lines of what the plane would require. The Park 400 is right at the specs. and the 450 would provide a bit more power than the specs. call for.

A big factor is the battery you plan on using as well. Are you going to run 2cell or 3cell?
