I have the Alpha .40 and I like it a lot. The engine is an Evolution .45, not a .52 but it has plenty of power. The three blade prop slows it down a lot. After I soloed, I switched to an APC 11x7 prop and the speed and climbing improved dramatically.

I had issues with the strength of the firewall and rear stabilizer joints, but they were easy fixes.

I also had some engine tuning issues, particularly when it got colder. During the summer, it was rock-solid, but when the temp got down into the 30's and 40's, it got finicky. I had to remove the limiter on the high speed needle valve in order to get enough range. It is just a roll pin stuck into the side of the knob. A quick snap and it was gone.

Good luck.


Edit - and the stock wheels are fine for a grass field.....
