RE: ACE R/C 4-40
The 4-60 is a good flying plane too. A friend of mine had one he made the same modification I did to mine (seriously reduce the amount of dihedral) and watched him fly that plane many times. I had the chance to fly it a couple of times and the only difference I noticed was that was bigger. When I did take mine out I looked into getting another one but alas by that time ACE R/C was out of business.
The one plane of the series that I wanted some day was the 4-120.
