Patternguy,

7 pounds is a very easy to reach....the 1st deception I did with old foam wing( by old foam- mean 1pound virgin) and watching the wood using all contest grade my plane came out at 7.0 pounds RTF - fuel... I know there is another 7 oz to take out of the plane with new foam .76 pound foam and a lighter fiberglass canopy layup and a few other tricks.. So we are hoping the electrics come out at 6.5 to 7 pounds RTF with battery.

The spine on the fuse from the canopy to tail is a trait of the Mach One..

Good luck with the project.....
