RE: TMPRO EXTRA 260
well this last week I had to rip off the covering just to repair the ribs. Not sure what they use for wood or where they get it from. Definately some crappy balsa wood. Every single rib need to be patched and or strengthened. Also had to add carbon fiber for the wing anti rotation pins. Did not find any type of wood dowel or and other material like the manual said was included. Had to shave off about .175 off the end of the wing tube to allow the wings to be tight against the fuse. The screw they include to join the wings together is a joke. Well the big test will be tonight. After some much need improving and upgrading of the air frame I will finally fly it tonight.
