My buddy has the rcsuperstore extra. He had a 3W 106 with cans in it. It flew great and awesome power. The price is right! We never weighed his but it flew like it was 25-26 lbs. I would guess it would be in the 23lb range with the 80. That is just speculation. If you search this site for that plane and engine I bet someone has tried it.

Wow , that new aerotech airframe looks like it'll be exactly what I'm looking for. Bterry, do you know any of the specs on that extreme extra? primarily weight and Will it accept a can muffler? If I don't pick something up at the toledo show I'll probably wait for the aerotech to come out as I'm in no real hurry. That is unless someone comes up with a better suggestion.
