Hey all!! I just bought the Hangar 9 Cap 232 .40. I am looking for a good .91 size 4-Stroke engine.

Money is a little problem. If the Saito would be a better choice and have more power and less weight than the Magnum .91 FS, then I would go with the Saito.

Now, here's my question: I want this Cap 232 to be able to hover and do 3D aerobatics with plenty of power behind it.
Would you guys recommend the Magnum .91 4-Stroke, the Saito .91, or the O.S. .91 engine. I would buy these engines brand new from a dealer here in Hays, KS. Please advise. I would really appreciate any help or comments you could possibly give me.
