Modified Legacy.
I have the new Legacy kit built up to just about ready to assemble. Everything fits where it's supposed to. Everything needed for the final put together is built. I will build a turtle deck instead of carving the big balsa block and use a Gypsy canopy instead of the one provided in the kit. I have a box of unused parts from the kit that I either didn't use or made others from lighter wood. The fin/rudder is 1/8 instead of 1/4 and shaped differently. An electric conversion kit replaced a lot of the plywood parts and 1/64 ply replaced the 1/16 doublers. I had some pre made wing skins so I used them for the wing center section and left over sheets for the leading edges. As it site now the frame weighs 28.5 ounces Ad in the motor and battery and it's up to 50 ounces. I weighed the left over wood pieces and they are 29.0 ounces. I squared off the wing tips and stab tips because of the amount of carving involved and weight. Doing that increases the area of both. I also widened the elevators 1/2 inch. The rear push rod exits the fuselage so I can adjust it easier. I also don't like to cut the fuselage at all to install the wing. With the clevis and 4-40 adapter removed from the wire the wing will slide through the opening nicely. I also made lines on the fuselage on the wing chord line so I can get the flaps set to zero on the bench. The plans call for wing mounted gear so I used aluminum fuselage mounted gear. More weight savings. I didn't use any of the cap strips from the kit. I cut them from the wing rib sheets, after removing the ribs of course. I added the turtle deck this morning. The wing is glued in and the push rods are soldered and ready for action. The bellcrank post is back to the steel rod.
I have a Legacy I built for gas power and then converted it to electric. It weighs 56.7 ounces without the battery in flying condition. Ad in 12 ounces for the battery and it's almost 70 ounces. I used everything in the kit for that one. Except the decal. And the wing mounted gear pieces.
