I am thinking the ZDZ90 might be about right for this plane- would come in at about 22#
Too bad the mintor 75 twin is not in stock right now.

For me a plane at 'book' 20.5# is a bit heavy for a 55cc; the DLE60 twin is nice, but has the performance of a 55RA. I think the R90 will need a bit more displacement than 55cc.

Agreed that the color is not as striking as the R70, but the white space leaves room for some custom vinyl to dress it up.

I would like to know more about the airfoil - semisymmetrical, or fully symmetrical. Would be nice to have the build manual on line for servo placement (pull pull vs aft mount rudder, etc).
