I had a Hammer a few years ago and loved it! I bought it at an auction for $40 including the engine and servos. It may have been a larger one, but had an OS 40 Fp in it and flew great. I flew the crap outta' that plane, and it was one of the most stable planes I've ever had. (It was a tail dragger.)

I was able to slow it down and fly it around the perimeter of the field at just over a walking speed. One other thing, I was doing a low inverted pass over the field and dumb thumbed it. The plane cartwheeled down the runway about eight times, the only damaged was to the wing mounting block, and I had it flying again within a couple days.

I think you'll like it, and if you don't let me know.
