How many square inches of wing and / or ounces of airframe can a 0.52 cuin 4-stroke glow engine handle for sport-aerobatic performance?

I am trying to find a proper model airplane project (from plans, kit or ARF) for a new Magnum XL-52RFS.

Thanks!

Basically any .40 2-stroke size plane

Thank you, Mike.

I had made a comparison among the recommendations for 2 and 4 stroke for several of the ARF's and kits commercialized by Tower Hobbies, and the rate is about 30% more displacement for an equivalent 4-stroke.

In this case: 0.52 / 1.3 = 0.40

mine (mag 52 fs) hauls a spad that weights 5.5 lb around quite well with a 11x7 prop, it doesnt have crazy vertical but it good enough for most people that just floating around most of the time, and it has enough vertical for good loops/hammerheads/ and other basic stuff but it will top out after 150-200ish feet so dont expect a rocket (its vertical would improve w/ a 12x5 or 13x4)
a uproar/th fun-51/escapade anything below 6lb should be ok, although 4.5-5 would be a lot better

IIRC, the Phoenix Decathlon calls for a .52 four stroke. That plane is really pretty, built well, and inexpensive. Flies nice, too.
