My first one (yellow and purple, with turtle deck) was powered by a Fox .46 BB abc. Lots of power for a .46, that engine. Was best with a 11x5 three-blade carbon prop. Don't know the weight, but it was completely covered with monokote (I doped when I was young, but the guy at the RC hobby shop told me no one does that anymore--boy was he wrong) and I think it was a few ounces lighter than my latest, which is 62.5. It is powered by a Stalker .55 rear exhaust. It is covered with oz cover and painted with dupont Centari Acrylic Enamel with glossy catalyst. No clear needed with acrylic enamels. Starting to get a little hangar rash on the wingtips from carrying it, though.
