if you want to use the engine you will need for the corsair than a Hangar-9 60 size ARF would be a good start there pretty forgiving not like a trainer more like a sport plane with warbird looks.
with the help of a instructor,they can be flown as a second plane, after getting the trainer dialed in,and with some help,the H-9 planes are still point and shoot with little or no self recovery,but contrary to some there good solid flyers when you get used to them,the 2 I have I could have flown them as second planes.
there both more stable than the plane I used as a second plane, I did get some help flying and trimming the first H-9 plane I have a P-40,the mustang I trimmed and maidened myself,a great flyer both I power with OS 91 4strokes,they can be powered by electric if your heading that way for power.
one thing to consider when your powering a larger plane like a 60 size warbird with batterys, is the power draw and battery requirements, the batts are not cheap theres a lot of power needed to fly them and if you expect to get a few flights per flying day than you will need more than one set unless you don't mind waiting by the charger to finish charging that one set you have.
its why I use nitro fuel to power my planes.
