I agree with you that a .60 size model could work, but I am spending too much time  already trying to pack an engine/fuel tank in to a too small .46 or .60 size plane.  Then, as I'm sure you have experienced, you often end up having to add weight to the tail to compensate for the added engine weight.  If I go gas with either the DLE 20cc or JBA 15 I am thinking I will go up in plane size as while.  Besides, as I get older I kind of enjoy the models with a wingspan of about 72 inches. 

I do appreciate your thinking of the options available however.  I have never owned a gasser, but I have noted the dimensions on these gas engines.  Looks like you need about another 1.5" or so for the rear mounted carburetor on the DLE 20cc.  I guess you could do a cut out in the fire wall. 

Thanks for the input.  Food for thought.
