I agree with Rodney. I have a OS FS 120S III and (for me) it has just the right amount of power. My plane came in at 10 pounds (on one scale) and 11 pounds (on another
scale). I maiden flew the plane today and with the engine running very rich I could go verticle for about 200 feet straight up. However, it slowed down to a crawl for landing.
Here's a video of the maiden. Nothing exciting, but then again, that's what it's suppose to be like on the maiden flight
