Hi Joe, I had a set of the Geizandanners (Kraft) long ago . They were a bit bulkey for 60 size planes-not a problem now. The main problem was that they were not fused or clutched and if they jam before the end points this would lead to the all important smoke being let out of the components or worse the power lines melting with the possibility of conflagaration. Solve that problem and it should be a good deal. Scott
