My 4 star 1.20…. Clipped two bays out of each wing side, put on a saito 1.80, enlarged the tail and rudder areas, set the wing up for "crow" and flaps. I am in a re-make now going to cut the rudder size back down, removed the crow option, trying to get lighter. The gear is soft and too low, Graph tech makes a carbon fibre one I may use. This is a Sunday Flyer. The 1.80 sucks up the fuel. Fun to fly, but…. just Fun to Fly.
