A friend of mine has an alpha 60 trainer RTF with about 12 flights and no crashes on it. He wants to sell it with the simulator for $300. I am just wondering if its a pretty good deal and if it would be worth putting a four stroke in it. I just like the sound, and what ive heard about the torque, and fuel economy of a four stroke. From what I hear the plane is a good plane to learn on. I have flown a few times with help and am trying to learn as much as possible, so any input suggestions or comments would be greatly appreciated. Thanks.
