OK guys, just finished building the e-flite mini edge 540 and I have to say that it was a disappointing project. I have built everyting that e-flite has put out, and some of them twice. The edge started off bad and went downhill. The ailerons were slotted and then covered which made it difficult to find the hinge locations especially since there are at least two thicknesses of covering at the leading edge. The landing gear bolts were only slightly off while one of the wing bolt holes had to be opened up about 1/8 of an inch to mount the wing. The elevators were twisted. I was able to get it almost flat, but it is still slightly warped. I installed the Park 400 4200kv motor and opted to go with the rudder servo in the tail. Even with the receiver and esc as far forward as it would go in the fuse, the plane was tail heavy. Had to add about 1/4 oz. of lead in the cowling. Speaking of the cowling, the stripes don't line up very well. With the stock gearbox, the lower standoff lugs had to be shaved for the cowling to go back far enough to get the prop to mount properly.I could go on about other problems, but my point is that as long as I waited for this plane to come out, I expected the quality to be better than what I received. I have built two of the mini funtanas and we are still enjoying them. Maybe I just got a dud. For $99.00 it's still a neat little plane. Maybe it will fly better than it assembles.
