I'm in the process of selling one that I've owned for a couple of years and powered with a Saito .91 and a 13 x 8 prop. Tried a 14 x 6 and found that it tended to slow the plane down too much at idle. The pluses are many and the model quality is very good as are most WM ARF's. It flies like it's on rails and gives the impression of being a larger ship if you're into scale aerobatics. The negatives were a somewhat flimsy landing gear and a tendency to snap with full elevator inputs at high speeds - Then again most CAPs will snap like that.
Think twice about putting servos in the tail area since the CAP comes out tail heavy to begin with and even with the .91 it took some nose weight to balance. You might consider Hitec 425s to 625s if you go with the larger engine. Although the 225s have lots of torque, their gear train is somewhat light and they lack holding power for the larger engine's loads.
I would recommend it if you are looking for a .46 sized CAP, yet also look into the GP Extra-300 in that range. Having owned and flown both with the same power plants and radio packs, I opted for the Extra.
